Question

where does external respiration take place?
o inside the body cells to produce atp
o between capillary blood and cells of the body
o between the alveoli of the lungs and capillary blood
need help? review these concept resources.

Explanation:

External respiration is the exchange of gases between the alveoli of the lungs and the capillary blood. It involves the diffusion of oxygen from the alveoli into the blood and carbon dioxide from the blood into the alveoli. The option "inside the body cells to produce ATP" refers to internal respiration (cellular respiration). The option "between capillary blood and cells of the body" is also related to internal respiration (gas exchange at the tissue level).

Answer:

between the alveoli of the lungs and capillary blood
