Capillaries: Capillaries are the smallest blood vessels in the body, where the actual exchange of oxygen, nutrients, and waste products occurs. They have thin walls that allow for easy diffusion of substances between the blood and surrounding tissues. Capillaries connect arterioles to venules, forming an extensive network throughout the body.
