HEREDITY


Heredity is the transmission of characters from one generation to another. In sexually reproducing organism there is the need of two parents to undergo reproduction, of which one is male and other is female. The gametes produced by the male are called the sperms and the gametes produced by the female are called the egg. These gametes have in them the DNA which is the genetic material. Fusion of the two gametes ie. egg and sperm leads to the formation of a zygote. So the zygote has in them the characters coming from two parents, which ultimately leads to the formation of an organism. As the organism is produced with the help of two parents, so there is the occurrence of variation. Therefore in heredity we find two things one is transmission of characters and other is the variation.
In Asexually reproducing organism, only one parent is sufficient to give rise to an organism , so genetics constituents of a parent and of the next generation is exactly same and therefore we are not finding variation in Asexually reproducing organism. Here we are finding a terminology called DNA copying, which means DNA of the parent is doubled and transmitted to the next generation.
DNA is the genetic material, it is the information source for making proteins in the cell. A section of DNA that provides information for a protein is called Gene. Proteins here are enzymes. If the enzymes that are produced work efficiently than lot of hormones are produced which play a role in shaping a character and its transmission.
Gregor Johan Mendel is known as the father of Genetics. Mendel did experiments on garden pea /Pea plant (Pisum sativum) as the plant was easy to grow, large number of breeding verities was found. Mendel became successful  as the pea plant had a very short life cycle and he was able to do both cross fertilization and self fertilization. He took seven pairs of contrasting characters to perform  Monohybrid , Dihybrid  etc. experiments.
We have 23 pairs of Chromosomes, out of which 22 pairs are called autosomes and 1 pair is called Sex chromosome. Autosome pairs are same for both male and female but they differ in Sex chromosomes. Male has XY sex chromosomes and Female has XX Chromosomes.

UNIVERSAL BROTHERHOOD DAY

 

In the year 1886 Swami Vivekananda became Sanyashi. He had a great quest to know India and people of India , its culture , heritage and geography, so he started Bharat Parikrama  in the month of July 1890 on foot  and travelled all throughout India and finally reached Kanyakumari on 24th December 1892. After reaching Kanykumari he lost his peace of mind and was completely depressed on finding the present scenario of the country. People were not getting enough food to eat, they were fighting in the name of caste, religion, language, rich- poor etc. People had forgotten their past glory and were lacking in self confidence. Indians started considering themselves as slaves under the British rule. Tears started rolling down from his eyes and he was trying to get the answers, how to rejuvenate India and how to put India in the throne of JAGAT GURU then, at that moment he saw from the shore of Kanya kumari, a big rock in the mid of Indian Ocean and  decided to meditate there. But as he was a sanyashi , so he had no money and no boat man was  interested to take him there. Without wasting any moment he swum and reached the mid sea rock and mediated there for three nights and three days, that was on 25th to 27th December 1892. He mediated on past, present and future of India. After 3day he sprang up and shouted, “I hit upon an idea……..’. That idea was to reunite all the Indians and to make them understand their past glory. The vision of one India was laid. From here a feelings of brotherhood spread length and breadth of India and tied everybody together. So it can be concluded here that the seeds of National Brotherhood was sowed for the first time in the fertile soil of India.


Before the advent of swami Vivekananda and his teachings, Indians localized themselves in small groups. They had revolted against British but those were to free themselves from the British imposed rules and for their own existence. Those revolts were not at all to free India from British. For example Farmers, Businessmen, sepoys, Kings and Kangs etc. all these sections had a revolt against British that is true but for their own and small cause, it was not for India as a whole. Farmers revolted to reduce their taxes and for owning the cultivable land, Businessmen also revolted as the finished products that time were coming from England. Sepoys had mutiny that was for religious ethics and kings fought against British only to safe guard their kingdom and to remained as rulers, for example Mysore , Jhanshi etc. But the thread for unifying India was not existing during that period of time otherwise British would had been thrown out from the country long time back. After the teachings and philosophy of Swami Vivekananda, feelings of oneness ignited every Indian mind and it would be difficult to find a single freedom fighters that time who was not influenced by the teachings and works of Swami Vivekananda, may it be Gandhiji, S.C. Bose, Bal Ganga Dhar Tilak, Sardar Vallab bhai Patel, Nehru, Chittaranjan Das, A.P.J Abdul Kalam, Indira Gandhi, Serojini Nidu, Rabiendra Nath Tagore,  Jamshedji Tata and host of others who were highly inspired and motivated by Swamiji’s words and work. So Swamiji was successful in raising the morale, confidence and infusing patriotic feelings among Indians. Thus the Seeds of Brotherhood sown in India.

Now coming to the World’s Parliament of religions, that took place for 17 days in Chicago, America from September 11th to September 27th 1893. Charles Carroll Bonney, Lawyer from Chicago and John Henry then the president of the organizing committee of World's Parliament of religions made it clear that the parliament was to show the richness and development of America to the rest of the world, Supremacy of Christianity over other religions and along with that to commemorate the completion of 400 years of  America Discovery by Columbus. On the first day that was on 11th September 1893, Swami Vivekananda was given a chance to speak for a small duration in the afternoon session, where he spoke for only three and half minutes but was able to catch every body’s attention there. His first sentence, “Sisters and Brothers Of America” electrified the whole Auditorium and all the people at once stood up and kept clapping for more than two minutes, that was a wonderful gesture given by Americans to welcome the Hindu Monk. Next morning all the Newspapers from America published regarding him, they referred him as cyclonic man, a man of wisdom, a man who overshadowed everybody in the parliament of religions and some newspaper even went further to publish his speech.

         A Busy road in Chicago-.

Swami Vivekananda’s first day speech to me is like a preface of a book where he gave a introductory regarding his motherland, the religion which he belonged, Regarding tolerance and universal acceptance, all religions to be true and sanatana dharma the mother of all religions, about the nation which sheltered refugees from other nations, all these were introduction  but nothing was in description. Those introductory sentences might had created curiosity and interest among the masses to know about India, Vedas, Puranas, culture etc. Here we find the adventurous and curious Americans left no stone unturned to get the nectar of Spirituality from the great saint Swami Vivekananda. After the first day speech, Swami Vivekananda became famous not only in America but also around the globe through Newspapers and Radio broadcasting.

The world Parliament of Religions which continued in Chicago for 17 days and if somebody dominated completely the duration with religious thoughts, religious belief, religious scripts, culture, logic and wisdom then it was only one man, the saint from India-Swami Vivekananda. After the first day(11/09/1893), Swami Vivekananda was invited again and again to give speech on different topics.

 Let me give a little idea related to the topics that Swamiji delivered during the Parliament of Religions.

1st speech 11/09/1893: Swamiji electrified everybody with his salutation “Sisters and Brothers of America”. He made the world clear that he was from a Nation and a religion which taught the world both tolerance and universal acceptance and thus in the first day itself he laid the stone of Brotherhood. Within his short duration of speech, four times swamiji pronounced that he was proud of the Nation and of Religion that he belonged, that showed his love for the country and its values.

2nd Speech 15/09/1893: Topic – “Why we disagree”- To explain the topic, Swami Vivekananda told a story of a frog. The story goes like this-

Once upon a time there lived a frog in a well and it had been living there for a long time. One day another frog that lived in the sea came and fell into the well.

” Where are you from ?” asked the frog from the well. “I am from sea” replied the frog that entered.

 “The Sea! How big is that ?…..is it as big my well?”, enquired the frog of the well after taking a leap from one side of the well to the other.

“ My friend “ said the frog from the sea, ”how do you compare the sea with your little well.”

Then the frog took another leap and asked” Is your sea so big?”. “What nonsense", replied the frog from the sea,” how you compare a well with the sea.”

Then the frog of the well  proclaimed that nothing can be bigger than his well and that frog was a liar and they threw him out from the well.

So swamiji through this story showed the difficulty that arise, the variation that develops and that leads to disagree. Hindu seats in his well and thinks whole world is his little well, Christians seats in their well and thinks that to be the world and same way Mohomodian seats in their well and believes that the world is like that.

Swamiji in his speech thanked America for taking steps in breaking the wall of each world and for giving an opportunity for every religion to understand another.

Thus in the second day of his speech, he gave another steps in developing brotherhood among all the people of the globe.

3rd speech 19/09/1893Topic-  Paper on Hinduism – In his third speech he spoke about Vedas. Swamiji explained about Accommodation and Spirituality that one would find in Hinduism. Swamiji made everybody understood  the concept of God, soul and body in Hinduism

4th speech 20/09/1893:  Topic – Religion is not a crying need for India – In that speech he placed in front of the world that Religion was not the important need of Indians. Instead of sending missionaries to India for spreading religion, it would had been better if AID were provided that would impoverished the masses in India.

     
     Art institute of Chicago where swami Vivekananda gave his speech,

   The stairs of the institute has the writings of Swamiji’s first day speech

Swamiji also stressed for Universal religion, where all the religion would remain but there would be ample scope for every religion to grow, in Swamiji’s words there would be infinite space for the development of every religion.

5TH speech 26/09/1893Topic – Buddhism in fulfillment of Hinduism- Swami Vivekananda in his speech explained about Buddhism and its origin. He also made it clear in front of everybody that Hinduism could not live without Buddhism and nor Buddhism could live without Hinduism.

6th speech 27/09/1893Topic – Concluding Speech- That was Swamiji’s concluding speech in the concluding day of the parliament of religions. Swamiji was invited to address the final session. Swamiji in his bold voice made it clear that the parliament of religions was not for the victory of one religion and destruction of other and each religion should assimilate the spirit of other religion and should preserve its individuality and grow. He stressed that Religions should help and not to fight.

Swamiji wanted that the science of the west and spirituality of India should combine together for the progress of the world.

Swamiji thus gave to the west, the nectar of spirituality of India and values from our Vedas and in return Americans  also did not fail to play their role. Within a short period of time Swami Vivekananda had thousands of Disciple in America and England. People of America showered him with so much love and respect that none before him might have reached that pinnacle. Roads were named after him, Art institute of Chicago where swami Vivekananda gave his speech, the stairs of the institute has the writings of Swamiji’s first day speech.

Later on, to commemorate Swami Vivekananda’s iconic speech that propagated religious tolerance and harmony, Universal brotherhood day was coined. It is observed on  11th September around the world to honour the historic speech delivered by Swami Vivekananda on this day in 1893.

SEX DETERMINATION

 SEX DETERMINATION: Sex determination deals with the occurrence of sex in the next generation, or it can also be spoken as- occurrence of  sexes of organisms. Earlier it was believed that women plays a great role in determining the sexuality of an organism but later on scientifically it has been found that it is not the female but Male who are the determiner of sex for the next generation. 

Higher Organisms  are 2n, means they are diploid. We have 23 pairs of chromosomes ie. 46 number of chromosomes. Out of 23 pairs or 46 number of chromosomes, 22 pairs or 44 number of chromosomes are called autosomes and one pair or 2 chromosomes are only sex chromosomes.

23 pairs of chromosomes an organism has 50% come from the mother side and other 50% come from the Father side.

Sexually reproducing organism produces gametes and the gametes are produced after Meiosis division or reduction division. Male gametes are called Sperms and female are called egg or ova.

Due to sexual reproduction both the both the gametes  ie. Sperm and an egg unite together to form Zygote. Zygote leads to the formation of an embryo or the future organism.

Dihybrid Cross

 Dihybrid Cross: For conducting Dihybrid cross, Mendel selected 2 pairs of contrasting characters. Earlier Mendel took one pair of contrasting character for conducting his monohybrid experiment. For the dihybrid experiment, Mendel completed his experiment in the following way -

1st pair - Height             contrasting characters          Tall( TT )         and      Dwarf( tt )

2nd pair Seed shape        contrasting characters         Round( RR )    and      Wrinkle( rr )

For dihybrid experiment Mendel took dominant characters in one side and crossed it with the recessive characters in the following way-

                                       Tall Round     x    Dwarf Wrinkle

                                             TT RR                  tt rr

Ratio that he obtained from the dihybrid cross is 9:3:3:1

While doing this experiment Mendel formulated his another most important Law, "which is Law of  Independent Assortment".

Mendel found that the parental characters of Dihybrid experiment assort out independently in F2 generation.

That means -Tall Round(TT RR )  when crossed with Dwarf Wrinkle ( tt rr ) the F1 generation became Tall Round with the genotype (Tt Rr ), but in the F2 generation parental characters ie. TTRR and ttrr reappear.

Some Important Terminology:

Phenotype: Visible expression means can be seen, like tall or dwarf.

Genotype: Genetic constitution of individual, which cannot be seen. Like tall may be TT OR Tt. These  TT or Tt which are found through genetic study, known as Genotype.

Homozygous :      The organism carrying similar alleles for a trait, eg TT or tt.

Heterozygous :     The organism carrying different  alleles for a trait eg Tt

F1 Generation  :    The first Filial generation

Gametes         :    Reproductive unit, ( Sperm and Egg in case of human beings)

Dominant allele :   The parental character that occurs in the next generation.

Recessive allele:   The character which is unable to be expressed and remain suppressed is called Recessive allele

MONOHYBRID EXPERIMENT AND LAWS

For doing monohybrid experiment Mendel took one pair of contrasting characters from his selected seven pairs of contrasting characters.As Maendel took one pair so it is known as Mono and crossing as hybrid.From the crossing the ratio that is obtained, he named it as monohybrid ratio and it is 3:1


   7 pairs of characters that Mendel took

First experiment in monohybrid cross he took the pair Height. Height has two contrasting characters one is tall and other is dwarf. For tall he gave the symbol TT which is dominant and dwarf is recessive so he used the small letters of dominant ie. tt.
From the monohybrid cross Mendel formulated two laws ie. Law of Dominance  and Law of segregation.

Law of Dominance- Mendel stated the law in this way- One factor in a pair may express itself and prevent the expression of other. The factor that  expressed itself was described by Mendel as dominant factor and unexpressed one is the recessive factor.


That means that character from father and mother come through gametes. Gametes unit to form zygote and later on leads to the formation of an organism. Sometimes character of father is dominant and sometimes mother's character. The dominant character is expressed in the F1 generation. F1 means first filial generation ie son or daughter.

Law of Segregation:  Segregate means  to separate. In the F1 generation we found that the character is tall and it comes from Tt . But these two allele never get mixed up or are contaminated, they simply remain together and has a tendency to get separated. And this separation occur in the F2 generation, where we find the parental characters to  reappear ie. TT and  tt. This is segregation.

HEREDITY

 

Higher Organisms  are 2n, means they are diploid. We have 23 pairs of chromosomes ie. 46 number of chromosomes. Out of 23 pairs or 46 number of chromosomes, 22 pairs or 44 number of chromosomes are called autosomes and one pair or 2 chromosomes are only sex chromosomes.

23 pairs of chromosomes an organism has 50% come from the mother side and other 50% come from the Father side.

Sexually reproducing organism produces gametes and the gametes are produced after Meiosis division or reduction division. Male gametes are called Sperms and female are called egg or ova.

Due to sexual reproduction both the both the gametes  ie. Sperm and an egg unite together to form Zygote. Zygote leads to the formation of an embryo or the future organism.

As the chromosomes come from two organisms to form zygote, therefore the organism that is formed shows variation .

Variation is a change due to which the species have equal chances of surviving in the environment they remain.

Chromosomes are the hereditary vehicles. It is long, slender thread like structure. Genes are present in the chromosome and it contains genetic materials. Chemical nature of gene is called DNA. Characters of father or mother that occurs in gametes are the DNA that is present there. Characters are also known by another name called Traits.

Gregor Johan Mendel is known as Father of Genetics .He did experiment on garden peas and blended his knowledge of science and mathematics to get the result of his experiment. He was the first person to give the information that the characters are transmitted from father to son. For doing his experiment  Mendel took 7 Pairs of contrasting characters. For example Height is a character which have two contrasting characters like Tall and Dwarf( Dwarf means short). When we say the person has height means he may be tall or short but it doesn’t mean that the height is tall.

With the garden peas Mendel conducted many experiment, which are known as  Monohybrid , Dihybrid  and Poly hybrid experiment. 

Monohybrid Experiment or Mono hybrid cross: For conducting the monohybrid experiment Mendel took one pair of contrasting character. One pair means mono and crossing them is the hybridization (or hybrid), the ratio of mono hybrid experiment is 3:1 .

Dihybrid Experiment or Dihybrid cross: For conducting the dihybrid Mendel took two pairs of contrasting characters. The ratio of Dihybrid cross is 9:3:3:1 .

From these above crosses Mendel formulated his famous laws, which are known as –

Law of Dominance, Law of segregation and Law of Independent assortment

Some Important Terminology:

Phenotype: Visible expression means can be seen, like tall or dwarf.

Genotype: Genetic constitution of individual, which cannot be seen. Like tall may be TT OR Tt. These  TT or Tt which are found through genetic study, known as Genotype.

Homozygous : The organism carrying similar alleles for a trait, eg TT or tt.

Heterozygous :  The organism carrying different  alleles for a trait eg Tt

CONTROL AND COORDINATION:

Nervous system is a system of highly specialized nerve cells , nerve fibres and organs that continue and control the activities of different parts of the body. This is done by converting external and internal stimuli of environmental changes into the form of electrical impulse( a process called transduction) and transmit them into a specialized called effectors(muscles, glands etc.) to react accordingly.


Between the receptors and effectors are the conducting cells of nervous system, called neurons. Neurons are the structural and functional unit of the nervous system that forms a complex network of communications by spreading throughout the organism.




Reflex action:(Marshal Hull, 1833) is an immediate involuntary action of any organ or part of the body in response to the particular stimulus. The function or action occurs immediately, without the involvement of will or consciousness.

Reflex arc: The nervous pathway taken by nerve impulse in a reflex action is called reflex arc.


Examples of reflex action:

1) Blinking of an eyelid when a moving object approaches the face.

2) Sneezing is a reflex action to the stimuli in nose.

3) Salivation occurs at the sight of food.

4) An  immediate removal of hand when it touch hot bodies.


Importance of reflex action:

1) It enables the animal to respond immediately to a harmful stimuli so that the no harm is caused to it.

2) It relieves the brain of too much work as the responses of routine nature take the form of reflex actions. If the animal is to exercise its will every time a wave of peristalsis occurs in the intestine, then the brain would soon become exhausted.

POST FERTILIZATION CHANGES (In Humans):

 

POST FERTILIZATION CHANGES: Fusion of male and female gamete leads to the formation of zygote. Zygote divides rapidly by mitotic division as it moves through the isthmus of oviduct towards the uterus. This is called cleavage and the cells that are formed are called blastomeres. From single cell zygote there is the formation of 2 cells, 2 to 4 cells, and then 8 cells. 8 cells then leads to the formation of 16 cells. This condition of 16 to 32 solid ball of cells is called Morula.

Morula – It is the solid mass of cell comprising of 16 – 32 cells formed from the zygote by mitotic divisions (after 5th cleavage). It takes approximately 3 days. A morula can be differentiated from blastula in the absence of cavity. It looks like a mulberry shaped ball of cells. The morula reaches the uterus about 4-6 days after fertilization.


In mammals due to the presence of insignificant amount of yolk, cleavage division cut the ovum into complete daughter cells. This type of cleavage in mammalian egg is termed as holoblastic.  Cleavage in the mammalian egg takes place during its passage through the fallopian tube to the uterus.

The outer layer of cells become flattened and is termed as Trophoblast, which absorbs fluids from the uterus. These fluid absorbed by the trophoblast gets collected in a cavity called blastocoels, or blastocyst cavity. As the quantity of fluid increases , the morula increases rapidly and assumes the shape of a cyst, which passes further into the uterus.


The blastocytes has over 100 cells. The portion of the blastocytes where the embryonal knob located lies against endometrium.

Implementation is the attachment of the blastocysts in the uterine wall. It takes place about seven days after fertilization.

Role of Zona Pellucida : The function of zona pellucida is to prevent the implementation of the blastocyst at an abnormal site.

The trophoblast of the invading blastocyst develops the rudiment of chorion, an extra embryonic membrane, which later forms placenta. The chorionic cells secretes a hormone named human chorionic gonadotrophin ( hCG), which resembles and takes over the job of pituitary LH during pregnancy.

Finally transformation of the blastula into gastrula takes place. Gastrula has three primary germ layers. In this stage morphogenetic movements takes place.

FERTILIZATION IN HUMANS:

FERTILIZATION IN HUMANS: The sperms present in the semen travel a long distance, from the uterus to the Fallopian tube. The sperms swim in the fluid medium of  the female genital track which is also partly helped by uterus.

Sperms swims at the rate of 1.5 to 3 mm per minute. A single ejaculation of sperms contains about 200 to 400 million of sperms in some 3ml. of fluid secretion. The sperms remains active for 24 to 48 hours after that it exhausts its energy and dies. 

Increased levels of GnRH stimulates the anterior pitiitary gland which then secretes the FSH and LH .FSH stimulates sertoli cells to secretes some factors which helps in spermatogenesis.

The motile sperms swim rapidly the cervix, enter the uterus and reaches the ampullary - isthamic junction of the oviduct, where the fertilization takes place.




A sperm comes in contact with the zona pellucida layer of the ovum and induces changes in the membrane to block the entry of the additional sperms.

The enzyme of the acrosome of sperm help to dissolve zonna pellucida and plasma membrane of the ovum and sperm head is allowed to enter into the cytoplasm of the ovum. This includes completion of Meiosis II to form secondary oocytes and II polar body.




The activated spermatozoa undergo acrosomal reaction and release various chemicals, like hyaluronidase that acts on the ground substance of follicle cells, corona penetrating enzyme that dissolves corona radiate, and zona lysine or acrosin that help to digest the  zona pellucida.All these chemicals are contained in the acrosome, located at the tip of sperm head and are collectively termed  sperm lysins. Fertilization of egg with only one spermatozoan is known as monospermy.

Numerous physical and chemical changes occur in response to egg- sperm binding. First egg become activated and undergoes depolarization of its membrane. Second the egg exhibits cortical reaction and shows zona reaction, which makes egg impervious to any other sperm.

As the fertilizing sperm enters the ovum it usually looses its flagellum. The sperm entry stimulates the egg to complete its second meiotic division.

Ultimately diploid zygote is formed by the fusion of a sperm with an ovum.

LUNG CAPACITY


Comparative study on capacity of lungs of normal people and smokers under different age: 

Lungs are the vital organ of the body. Lungs occurs in pair and are spongy and it is located on the either side of the chest. The lungs are covered by a thin tissue layer called pleura. A thin layer of fluid is also present which acts as a lubricant allowing the lungs to slip smoothly as they expand and contract with each breath. Air enters our lungs through nostrils, then trachea and bronchi and helps in the exchange of gases. Lungs are also important organ for the purification of blood. Lung volume  and the lung capacity refer to the volume of air in the lungs at different phases of the respiratory cycle. The average lung capacity of an adult human male is about 6 litres of air. The average human respiratory rate is 30 -60 breaths per minute at birth, then decreasing to 12 -20 breaths per minute in adults.


This is a survey based project which was undertaken to know the lung capacity of people in different age groups. Along with the different age groups, another division was made in each group that is of addiction like smoking, alcoholic etc  to find if there is any variation in lung capacity.


OBJECTIVE:

1)      To find the lung capacity of people under different age groups.

2)      To compare the lung capacity of normal and healthy people with that of smokers and addicted.


RESEARCH QUESTIONS:

1)      Lung capacity of smoker is less or more?

2)      Why the smokers have less stamina?

3)      Why smokers and addicted people become tired very quickly ?

4)      How lung capacity can be increased?

5)      Is the physical work efficiency of a normal and healthy person related to lung capacity?






METHODOLOGY

Ø  For doing this Project we have taken long polythene tube/bag of 100 cm

Ø  Then we conducted survey with the polythene tube

Ø  We asked people to blow air  at a single instance

Ø  Next we took the measurement of the inflated portion of the polythene tube

Ø  Then finally we took out the volume from the measurement that we obtain

Ø  In this way we took the measurement of number of people under  different age group.




1)      First of all we took out the circumference

Then the radius taken out by using formula 2Ï€r

Then the volume formula was used = 2 πr2h

Suppose a person blown air of 65 cm then

Circumference of polythene = 22 cm

Then the radius will be = 3.5 or 7/2

Now putting the value

The volume formula 2Ï€r2h

=2 x 3.14 x3.5 x 3.5 x 65

=38.5 x 65

=2502.5 cm3

 Average lung capacity of different age groups that we have surveyed

(group A to C are normal people and from group D to F are smoker of drug addicted)

GROUP A (age group  16 to 30 years age) ─2568.05cm3

GROUP B (age group  31 to 45 years age) ─2259.9cm3

GROUP C  (age group 46 to 60 years age─ 1661.2cm3

GROUP D  (age group  15 to 30 years age)─2013.6cm3

GROUP E  (age group  31 to 45 years age )─1701.7cm3

GROUP F  (age group 46 to 60 years age)─1362.9cm3


So it can be concluded that the lung capacity of smokers, addicted etc. is much less than the lung capacity of the people in their age group.

Lung capacity can be increased through Pranayam and Yoga
