What do the arteries do?
transfers blood away from the heart
Arteries are muscular blood vessels that carry oxygen-rich blood away from the heart to various parts of the body. They have thick, elastic walls that help maintain blood pressure and deliver oxygen and nutrients to tissues and organs throughout the body. The pumping action of the heart generates pressure that pushes the blood through the arteries, and the walls of the arteries can constrict or dilate to regulate blood flow and pressure. Arteries branch into smaller vessels called arterioles, which lead to even smaller capillaries where oxygen and nutrients are exchanged with the body’s tissues. From the capillaries, blood flows into veins that carry it back to the heart. Overall, arteries play a vital role in maintaining proper blood flow, blood pressure, and delivering oxygen and nutrients to the body’s organs and tissues.
