Overview. Arteries distribute oxygen-rich blood to your body. Arteries, part of your circulatory (cardiovascular) system, are the blood vessels that bring oxygen-rich blood from your heart to all of your body’s cells. They play a crucial role in distributing oxygen, nutrients and hormones throughout your body.
An artery (from Greek ἀρτηρία (artēríā)) [1] is a blood vessel in humans and most other animals that takes oxygenated blood away from the heart in the systemic circulation to one or more parts of the body.
artery, in human physiology, any of the vessels that, with one exception, carry oxygenated blood and nourishment from the heart to the tissues of the body. The exception, the pulmonary artery, carries oxygen-depleted blood to the lungs for oxygenation and removal of excess carbon dioxide (see pulmonary circulation).

May 9, 2019 · The aorta is the main systemic artery and the largest artery of the body. It originates from the heart and branches out into smaller arteries which supply blood to the head region ( brachiocephalic artery ), the heart itself ( coronary arteries ), and the lower regions of the body.
The aorta and its principal branches. The aorta is the largest vessel in the systemic circuit, arising from the left ventricle. It is commonly said to have three regions: the ascending aorta, the arch of the aorta, and the descending aorta; the latter may be further subdivided into the thoracic and the abdominal aorta.
Arteries are deep under the skin. They do not have valves to prevent blood from flowing backwards. Instead, every time the heart beats, the arteries stretch out so the blood has room to go through. Once the walls have completely stretched out, the muscles in the arteries make them shrink back to their normal size.
