Air leaving your lungs is higher in carbon dioxide than the air coming into your lungs.
Blood leaving the lungs is oxygenated
The diaphragm moves down to make the lungs expand (inhalation)
Inspiration, as called inhalation, moves air into the lungs. Expiration, as called exhalation, moves air out of the lungs.
The blood leaving the lungs is loaded with oxygen, while blood entering the lungs is about to get oxygen from the respiratory system.
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).
do you mean fills with air? if so then its the lungs
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.
