What is a capillory?

Answer 1

A capillary is a tiny blood vessel that connects arterioles and venules, facilitating the exchange of oxygen, nutrients, and waste products between blood and tissues. They have thin walls, typically just one cell layer thick, allowing for efficient diffusion. Capillaries form extensive networks throughout the body, ensuring that all cells are reached by blood. Their primary function is to enable the transfer of essential substances to and from the body's cells.
