Explanation:
Detailed explanation-1: -Oxygen diffuses through the capillary wall, into the tissue fluid and the cells. Carbon dioxide diffuses from the cells into the tissue fluid, then across the capillary walls into the blood plasma . Glucose diffuses from the blood plasma, across the capillary walls to the tissue fluid, and then to the cells.
Detailed explanation-2: -The three types of methods for capillary exchange are diffusion, bulk flow, and transcytosis. Diffusion is the primary mechanism by which small molecules flow across capillaries and into the interstitial fluid, and vice versa, from the interstitial fluid into the capillaries.
