Arterler, commonly known as arteries, are blood vessels that carry oxygen-rich blood away from the heart to various parts of the body. They are an essential component of the circulatory system, which also includes veins and capillaries. The walls of arteries are thick and elastic, allowing them to withstand the high pressure of blood 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. Maintaining healthy arteries is crucial for overall health, as conditions like atherosclerosis can lead to serious cardiovascular issues. Regular exercise and a balanced diet can help keep arteries functioning properly.
