The tiniest vessels in the body are capillaries, which are small, thin-walled blood vessels that connect arterioles and venules. Their primary function is to facilitate the exchange of oxygen, carbon dioxide, nutrients, and waste products between the blood and surrounding tissues. Capillaries are so small that red blood cells often pass through them in single file, maximizing their surface area for efficient exchange.
