LV receives the oxygen-rich blood from the left atrium and flows out of the LV into the aortic semilunar valve and into the aorta which carries it to all tissues in the body except the lungs 5. It is returned as oxygen poor blood and the cycle begins again Arteries Carry blood away from the heart to all regions of the body The aorta is the largest blood vessel in the body Carotid arteries carry blood away from the heart and towards the head The external carotid artery brings blood to the face Arterioles are smaller, thinner branches of arteries that deliver blood to the capillaries Capillaries are the smallest blood vessels in the body that play a role in delivering oxygen and nutrients to cells of the tissues Veins Form a collecting system to return oxygen-poor blood back to the heart Venules are the smallest veins that join to form larger veins Venae cavae are the two largest veins in the body Pulse and blood pressure The pulse is the pressure against the walls of the arteries caused by a contraction of the heart Blood pressure is the measurement of the amount of systolic and diastolic pressure exerted against the wall of the arteries Systolic pressure – caused when ventricles contract; highest pressure against the walls in the arteries
