Question

Why doesn't the lungs collapse after the force full?

Answer 1

Hey Mate

Here is your answer

Because of Residual Volume-
 RV is the volume of air that stays in the lung after maximal exhalation i.e. if you force all the air out of your lungs, with maximal effort, there would still be some air remaining in the lungs — about 1–1.2 liters — that no matter what, you cannot get rid of. Residual Volume has two functions:
1.It prevents lungs from collapsing between breaths. It’s a blessing because the effort to open a collapsed lung after each breath would be tremendous compared to inhaling against a partially deflated lung (so to say).
2.It keeps blood oxygenated between breaths.

Hope it helps

The lungs do not collapse even after forceful expiration as the lungs never become empty.There is always some amount of air left in the lungs which is known as residual volume.
