Question

Quizplus · Accepted Answer

Alveoli are small sacs in the lungs where gas exchange between the air and blood takes place. The more alveoli present, the greater the surface area available for the exchange of gases between the air and blood. This is important for efficient oxygen/carbon dioxide exchange in the lungs. Coronary arteries, parenchyma, and capillaries are not directly involved in gas exchange in the lungs.
