Question

the mechanism of gaseous exchange in human during inhale and exhale air​

Answer 1

Answer:

These are called alveoli. They inflatewhen a person inhales and deflate whena person exhales. During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Answer 2

Answer:

Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli
