Capillaries are the smallest blood vessels in the body, with a diameter typically just wide enough to allow red blood cells to pass through in single file. Their small size facilitates efficient exchange of gases, nutrients, and waste products between the blood and surrounding tissues. The thin walls of capillaries, composed of a single layer of endothelial cells, further enhance this exchange by minimizing diffusion distance. This structural adaptation ensures that oxygen and nutrients can quickly reach cells while allowing for the removal of carbon dioxide and other metabolic wastes.

What is the function of the capillaries in the human circulatory system?
The function of the capillaries in the circulatory system is to allow diffusion of wastes, oxygen, and nutrients to the tissues. The rest of the circulatory system is designed to move the blood to the capillaries so they can perform this function.

What is function of the blood vessels and capillaries?
The blood vessels, which include the capillaries, function to distribute nutrients such as glucose and oxygen to the body tissues and to carry wastes such as carbon dioxide and urea away from the tissues to be excreted.
