Question

Quizplus · Accepted Answer

The primary method by which materials are exchanged between blood and the surrounding tissues is passive diffusion across the capillary wall down their concentration gradients. This process allows for the movement of gases, nutrients, and waste products between the capillaries and the tissues they supply. Active transport, osmotic pressure, ultrafiltration, and reabsorption also play a role in this process, but passive diffusion is the main method.
