A. Superior VenaCava – A large vein that carries oxygen poor blood into the
heartfrom the upper body and into the right atrium.
B. Right Atrium – Blood from the vena cava enters into the right atrium and is
thensent to the right ventricle.
C. Inferior Vena Cava – A large vein that carries oxygen poor blood into the
heartfrom the lower body and into the right atrium.
D. TricuspidValve – The valve separating the right atrium and right ventricle,
preventingblood from flowing in the wrong direction.
E. Right Ventricle – Collects blood from the right atrium and then pumps it
throughthe pulmonary valve.
F. Pulmonary Valve – A valve that is between the right ventricle and
pulmonaryartery.
G. Pulmonary Artery – Carries blood from the heart directly to the lungs. It is also
theonly artery that carries oxygen-poor blood.
H. Left Atrium – Oxygen-rich blood from the lungs travel through the body and
intoheart through the left atrium.
I. MitralValve – The valve separating the left atrium and left ventricle,
preventingblood from flowing in the wrong direction.
J. LeftVentricle – Collects blood from the left atrium and then pumps it through
theentire body except the lungs. The left ventricle is stronger than the right
ventriclesince its pumps the blood through the entire body as opposed to just
thelungs.
K. Aortic Valve – The valve that lies between the left ventricle and aorta,
preventingthe blood from flowing in the wrong direction.
L. Aorta – Carries the oxygen-rich blood from the left ventricle to the entire
body,except the lungs. The aorta is also the largest artery in the body.
