B
capillaries.

C
veins.

D
venules.

Answer 1

Exchange of gases and other substances occurs in the capillaries between the blood and the surrounding cells and their tissue fluid

Hope this helps!

Answer 2

B. capillaries.

Step-by-step explanation:

The gas exchange mechanism that occurs in the pulmonary alveoli. This process is essential to ensure the transport of oxygen through tissues and blood and the removal of carbon dioxide. Oxygen gas is used by our cells to perform cellular respiration, a process in which the cell is able to produce energy

Each alveolus has a thin epithelial wall and a large number of blood capillaries are present around it. This arrangement of the alveolus is essential to ensure that the diffusion of gases occurs at the time of gas exchange.

Accordingly, we can conclude that gas exchange occurs between the tissue cells and the blood in the capillaries.
