The term 'Artery Major A' refers to four major arteries in the human body: the Aortal (6 letters), Carotid (7 letters), AORTA (5 letters), and Aortic (6 letters). The Aortal is the main artery that carries oxygenated blood from the heart to the rest of the body. The Carotid is a pair of arteries located on either side of the neck that supply oxygenated blood to the head and neck. The AORTA is the largest artery in the body and runs from the heart to the abdomen. Finally, the Aortic is an artery that branches off from the AORTA and supplies oxygenated blood to the lower body.
