What, physically, is lung capacity?

Question

Is it thicker/thinner lungs?

Stronger diaphram?

More air pockets? (I forgot what those are called, you could answer that, too)

Stretchier lungs?

Answer 1

The average total lung capacity is approximately 5.8 to 6 liters, however it varies from person to person, and is dependent on weight, s*x, age, and activity

Answer 2

The total lung capacity varies from 4000 to 6000 cc and depends on the persons age, weight , height, s*x and other factors like the altitude in which one lives and the physical ffitness.

Females have a lung capacity which is 20% to 25% lower than males. Tall people have a higher lung capacity. Those who live in higher altitudes have a higher lung capacity.

In certain lung diseases the lung capacity is low. Smokers have a lower lung capacity.

The lung capacity is the maximum amount of air that can be held in the lungs after a full inspiration.

The range 4000 to 6000 cc. takes into consideration of the

variation of the normal adult healthy people of different

stature living throughout the world.

The lungs contain about the same no. of alveoli about 300, 000, 000 per person.

The difference in the lung capacity depends on the stretchiness of the alveoli.

For example in an athlete the capacity of air held is more than in a non athlete.
