arterial expansion; can be felt in arteries near the surface of the body

A

pulse

36
Q

amount of pressure exerted by blood on vessel walls as the left ventricle of the heart contacts and relaxes

A

blood pressure

37
Q

ventricles contract and eject blood and pressure within arteries increases

A

postural or orthostatic hypotension

44
Q

replenishes the blood’s oxygen supply and eliminates gaseous wastes

A

pulmonary circuit

45
Q

transport oxygen, nutrients, hormones, and oxygen to body cells and transports waste away for their elimination by various mechanisms, including respiration, urination, and perspiration
