Question

question 24 1.67 pts oxygen and carbon dioxide are transported between the blood and interstitial fluid by way of active transport (using atp) by protein carriers of endothelial cells. diffusion from areas of higher concentration to lower concentration. exocytosis and endocytosis by endothelial cells. pinocytosis using fluid - filled vesicles.

Explanation:

Oxygen and carbon - dioxide move across the capillary walls between blood and interstitial fluid via simple diffusion. This is because they move down their concentration gradients without the need for energy (ATP) or vesicle - mediated processes.

Answer:

B. diffusion from areas of higher concentration to lower concentration.
