Correct Answer is A
Explanation
Choice A rationale:
Diffusion is the primary mechanism for capillary exchange. It allows small molecules, such as gases, lipids, and lipid-soluble molecules, to move directly through the membranes of the endothelial cells of the capillary wall.
Choice B rationale:
Filtration is a pressure-driven mechanism that moves volumes of fluid from an area of higher pressure in a capillary bed to an area of lower pressure in the tissues. However, it is not the primary mechanism for capillary exchange.
Choice C rationale:
Gravity does not play a direct role in capillary exchange.
Choice D rationale:
Colloid osmotic pressure is a type of pressure that interacts with hydrostatic pressure to drive fluid movement in capillaries. However, it is not the primary mechanism for capillary exchange.
