Peripheral arteries are blood vessels that carry oxygen-rich blood away from the heart to the limbs and other parts of the body. They are part of the circulatory system and include arteries in the arms, legs, and other peripheral areas. These arteries branch off from larger arteries, such as the aorta, and help supply essential nutrients and oxygen to tissues. When peripheral arteries become narrowed or blocked, it can lead to conditions like peripheral artery disease (PAD), which may cause pain, numbness, or other symptoms in the affected areas. Maintaining healthy peripheral arteries is crucial for overall circulation and can be supported by a balanced diet, regular exercise, and avoiding smoking.
