Pericardium 2 of 26 two smaller, upper, receiving chambers in the human heart Atria 3 of 26 two larger,lower pumping chambers in the human heart ventricles 4 of 26 name the 4 chambers right atrium , left atrium , left ventricle, right ventricle 5 of 26 name of the strong muscle wall septum 6 of 26 what does the aorta do ? carries oxygenated blood to all parts of the body. 7 of 26 superior vena-cava ? carries deoxygenated blood from the upper part of the body (head & arms) to heart 8 of 26 right atrium receives deoxygenated blood from the superior vena cavae 9 of 26 coronary artery supplies oxygenated blood to muscles of the heart 10 of 26 inferior vena cava carries deoxygenated blood from lower part of body to heart 11 of 26 pulmonary artery carries deoxygenated blood to lungs 12 of 26 pulmonary veins returns oxygenated blood from lungs to heart 13 of 26 left atrium receives blood from the lungs 14 of 26 coronary vein carries deoxygenated blood from the heart muscle 15 of 26 name the 4 valves tri-cuspid , bicuspid, pulmonary and aortic 16 of 26 tri-cuspid between right atrium and ventricle. three cusps 17 of 26 bicuspid valve between left atrium and ventricle. two cusps 18 of 26 pulmonary valve at entrance to pulmonary artery. two cusps shaped like a half moon(semi-lunar valve) prevents back flow into the heart. 19 of 26 aortic valve at entrance to aorta. (also a semi-lunar valve) prevents back flow from the aorta after contraction of the heart. 20 of 26 systole when the heart contracts 21 of 26 diastole relaxation the heart (die) 22 of 26 name the 3 blood vessels arteries , capillaries and veins 23 of 26 arteries transport blood Away from the heart. thick outer wall and thick layer of muscle. 24 of 26 capillaries found at end of arterioles. smallest vessels. 25 of 26 veins transport blood to the heart. have semi-lunar valves to prevent back flow into the heart. 26 of 26
