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 2πr

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 2πr²h

=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
