Question

17 what is included in the process of external respiration? multiple choice transport of gases via the blood pathway where oxygen is used by cells to produce energy gas exchange between blood and tissue cells gas exchange between the capillaries in the lungs and the air in the alveoli

Explanation:

External respiration is the process of gas exchange between the lungs and the blood. The gas exchange between the capillaries in the lungs and the air in the alveoli is a key part of external respiration. Transport of gases via the blood is part of the overall respiratory process but not specifically external respiration. The pathway where oxygen is used by cells to produce energy is internal respiration (cellular respiration). Gas exchange between blood and tissue cells is also internal respiration.

Answer:

Gas exchange between the capillaries in the lungs and the air in the alveoli.
