An artery is a major blood vessel responsible for carrying blood away from the heart to the peripheral tissues of the body. Characterized by thick, elastic, and muscular walls, arteries are designed to withstand the high pressure generated by the pumping action of the cardiovascular pump. Because of their structural composition, they can maintain continuous blood flow despite changes in systemic resistance, allowing the distribution of nutrients and oxygenated blood throughout the circulatory network. The structure and function of arteries are integral components of the closed circulatory system, regulating blood pressure and ensuring that blood reaches all necessary capillary beds.
