A capillary artery is a small, thin-walled blood vessel that branches from larger arteries and plays a crucial role in the circulatory system. It serves as a transition between arteries and capillaries, delivering oxygenated blood and nutrients to the tissues. Capillary arteries have a narrow diameter and numerous branches, allowing for efficient diffusion of substances between the blood and surrounding cells. Through their intricate network of capillaries, capillary arteries facilitate vital processes such as gas exchange, nutrient delivery, and waste removal in the human body.
