Arteries: Function and Exception of the Pulmonary Artery

Do arteries carry deoxygenated or oxygenated blood?


Arteries are blood vessels that carry blood from the heart to different parts of the body. Most of the time, arteries carry oxygenated blood from the heart, except for one specific artery – the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, where it is oxygenated by the process of respiration. The oxygenated blood then returns to the heart through the pulmonary veins and is pumped into the systemic circulation by the left ventricle via the aorta. In summary, arteries carry oxygenated blood, except for the pulmonary artery, which carries deoxygenated blood.
