Answer

Brief Explanations:

Gas exchange in the respiratory system occurs in two key locations: at the alveoli (lungs) where oxygen moves from the air into the bloodstream, and at body tissues where carbon dioxide (a waste product) moves from the tissues into the bloodstream to be transported back to the lungs for exhalation. The other options incorrectly identify the sites or direction of gas diffusion.

Answer:

Oxygen diffuses into the blood at the site of the alveoli, and carbon dioxide diffuses into the blood at the site of the tissue.
