what are the only arteries in the body that carry deoxygenated blood
Artery An artery (plural arteries) (from Greek ἀρτηρία (artēria), meaning 'windpipe, artery')[1] is a blood vessel that takes blood from the heart to all parts of the body. Most arteries carry oxygenated blood; the two exceptions are the pulmonary and the umbilical arteries, which carry deoxygenated blood to the organs that oxygenate it. The effective arterial blood volume is that extracellular fluid which fills the arterial system.
Blood vessel The blood vessels are the part of the circulatory system, and microcirculation, that transports blood throughout the human body.[1] There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart. The word vascular, meaning relating to the blood vessels, is derived from the Latin vas, meaning vessel. A few structures (such as cartilage and the lens of the eye) do not contain blood vessels and are labeled.
