yes
when you contract your diaphram, or the lung muscle, your lungs become somewhat empty. this is called a partial vacuum. this is something that air, water, anything that can go in try to fill. the lungs, now a vacuum, pull stuff, supposed to be air!,into the lungs.
when you breath in your diaphragm muscle expands your lungs to take in air. when you breath out your diaphragm muscle pushes on your lungs to let out the air.
Healthy lungs should have a soft and spongy texture. Some squishiness can be normal due to the presence of air in the lungs. If the lungs feel very firm or hard, it could indicate a health issue such as pneumonia or fibrosis.
The scuba regulator is supposed to keep the lungs at normal size; but you only have to move half as much "air" to move the same number of molecules.
Air leaving your lungs is higher in carbon dioxide than the air coming into your lungs.
when air moves out of the lungs, the air pressure decreases
The movement of air on and out the lungs is called respiration. The movement of air into the lungs is called inhalation (inspiration). The movement of air out of the lungs is called exhalation (expiration).
Loss of air in the Lungs.
No. They breath using their lungs or with their lungs, but not "through" their lungs. They do however breath "through" their blowholes (to get the air in and out of their lungs).
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
air sacs are in the lungs and when you breathe in blood carries it to the lungs.
Yes, snakes breathe air and they have lungs.
