Question

multiple cholce question when the intra - alveolar pressure decreases below the atmospheric pressure (760 mm hg), air will move ______ the lungs. out of into

Explanation:

Air moves from areas of higher pressure to areas of lower pressure. When intra - alveolar pressure (pressure inside the alveoli) is less than atmospheric pressure (pressure outside the body, in the environment), the higher - pressure atmospheric air will flow into the lower - pressure alveoli (lungs) to equalize the pressure difference.

Answer:

B. into
