Answer:
Air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere equal to the pressure in the atmosphere less than the pressure in the atmosphere greater than the pressure in the atmosphere greater than the intra-alveolar pressure
Explanation:
The Air we breath moves from a a region of high pressure to a lower one. As you breath in air into the body system, the air goes from your body outside to the lungs inside your body , so that the air in your lungs has a lower pressure.
That is to say, the pressure in the lungs decreases just as the rib-cage goes out and up, while the Air coming from outside gets in by other air particles due to constant pressure where the air moves from a high level pressure to a lower one.
Air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere.
The mechanism of breathing:
The movement of air out and into the lungs takes place due to a pressure gradient between the atmosphere and the lungs. Inspiration can take place if the pressure within the lungs, that is, intrapulmonary pressure is less in comparison to the atmospheric pressure.
During inspiration there is a negative pressure in the lungs with respect to atmospheric pressure. Similarly, during expiration, that is, when the air moves out, the intrapulmonary pressure is greater than the atmospheric pressure.
Thus, air moves out of the lungs when the pressure inside the lungs is greater than the pressure in the atmosphere.
