Paper 1
Revise: Cardiovascular System Structure and FunctionThere is a semilunar valve at each ventricular exit: one leading into the pulmonary artery and one leading into the aorta.
Define arteries and veins by the direction of blood flow, not oxygen content: arteries carry blood away from the heart; veins carry it towards the heart.
Remember the pulmonary exceptions: the pulmonary artery carries deoxygenated blood and the pulmonary vein carries oxygenated blood.
