An artery is a type of blood vessel that carries oxygen-rich blood away from the heart to various parts of the body. Arteries have thick, elastic walls that help withstand the high pressure of blood being pumped from the heart. The largest artery in the body is the aorta, which branches out into smaller arteries that supply blood to different organs and tissues. Arteries play a crucial role in the circulatory system, ensuring that all body cells receive the oxygen and nutrients they need to function properly. When arteries become narrowed or blocked, it can lead to serious health issues, such as heart disease or stroke. Maintaining healthy arteries is essential for overall well-being.
