10 Cards in this Set

  • Front
  • Back
valve
any of the valves that control blood flow to and from the heart and that include the atrioventricular valves, the aortic valve, and the pulmonary valve—called also cardiac valve.
artery


any of the muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body.


vein
any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
aorta
the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone.
capillary
any of the fine branching blood vessels that form a network between the arterioles and venules.
ventricle
each of the two main chambers of the heart, left and right.
vena cava
a large vein carrying deoxygenated blood into the heart
atria
is one of the two blood collection chambers of the heart
left ventricle
The left ventricle is one of four chambers of the heart. It is located in the bottom left portion of the heart below the left atrium, separated by the mitral valve. As the heart contracts, blood eventually flows back into the left atrium, and then through the mitral valve, whereupon it next enters the left ventricle.
deoxygenated blood


Deoxygenated blood is then pumped by the right ventricle to the lungs via the pulmonary artery which is divided in two branches, left and right to the left and right lungs respectively.
