Blood carriers are essential for the circulatory system, as they transport blood throughout the body. Veins, vessels, aortae, ARTERIES, and aortas are all terms used to describe these blood carriers. Veins are five-letter words that refer to the vessels that carry blood from the body back to the heart. Vessels are seven-letter words that refer to the tubes that carry blood throughout the body. Aortae are six-letter words that refer to the main artery that carries oxygenated blood away from the heart. ARTERIES are eight-letter words that refer to the vessels that carry oxygenated blood away from the heart. Aortas are six-letter words that refer to the largest artery in the body, which carries oxygenated blood away from the heart.
