pulmonary artery. Carries blood from right side
Aortic valve/ semilunar - Answers -The valve between left ventricle and the aorta.
Left AV (atrioventricular valve) / Bicuspid - Answers -The valve between the left atria
and the left ventricle. Carries blood from the pulmonary veins
Right AV (atrioventricular) valve/ Tricuspid - Answers -The valve between the right atria
and the right ventricle. Carries blood from the systemic veins
Aorta - Answers -Carries blood from the left side of the heart to the rest of the body's
organs
Pulmonary vein - Answers -Carries blood from the lungs to the left atria of heart
Systemic veins - Answers -Carries deoxygenated blood from body to the right atria of
heart
Pulmonary artery - Answers -Carries deoxygenated blood from the right ventricle to the
lungs
Inferior and Superior vena cava veins - Answers -Two largest veins in body that bring
O2 poor blood to the right atrium
Inferior Vena cava vein - Answers -Carries O2 poor blood back from legs and lower half
of body
Superior vena cava vein - Answers -Carries O2 poor blood back from upper body and
head
Chordae tendineae - Answers -Internal fibers connected to the semilunar valve walls
and to the ventricles by papillary muscles
Endocardium - Answers -Layer of endothelial tissue that lines the interior of each
chamber
Myocardium - Answers -Middle of the heart. Cardiac muscle tissue separated by
connective tissues and including blood capillaries, lymph capillaries, and nerve fibers
Contracts to pump blood from the heart chambers
