Heart and Blood Flow

largest artery in the body carrying oxygen-rich blood away from the the heart

blood vessel that transports blood away from the heart

upper heart chamber

smallest type of blood vessel and the site of gas and nutrient exchange between the blood and interstitial fluid

volume of blood ejected from each ventricle per minute

strength of a muscle contraction when correcting for the muscle length

phase of the cardiac cycle when the heart muscle relaxes and the heart fills with blood

diagnostic tool used to measure electrical activity in the heart

vein that carries oxygen-poor blood from the lower half of the body to the right atrium of the heart

contractile cell found in heart muscle tissue

cluster of noncontractile cells in the right atrium of the heart that regulates the depolarization of the heart muscle

blood flow from the right side of the heart, through the lungs, and back to the left side of the heart

artery that delivers oxygen-poor blood from the right ventricle to the lungs and branches to the left and right pulmonary arteries

vein that delivers oxygen-rich blood from the lungs to the left atrium of the heart

vein that delivers oxygen-poor blood from the upper body to the right atrium of the heart

blood flow from the left side of the heart, through the body, and back to the right side of the heart

phase of the cardiac cycle when the heart muscle contracts and blood is ejected from the ventricles

blood vessel that carries blood toward the heart
