Heart

circumflex a.

Supplies blood to the left atrium and posterior walls of the left ventricle

right atrium* and ventricle*

The tricuspid valve is located between what two structures? pumps blood into the pulmonary arteries This heart structure carries deoxygenated blood.

anterior interventricular a.

Anterior branch of the left coronary artery; lies in anterior interventricular sulcus.

pulmonary veins*

Deliver oxygen rich blood from the lungs to the left atrium

aorta*

Largest artery in the body The large arterial trunk that carries blood from the heart to be distributed by branch arteries through the body.

right coronary a.

Origniates above the R cusp of the arotic valve. Supplies blood to R ventricle and 25-23% of L ventricle. Gives off Posterior Descending Artery. Often supplies the SA nodal artery.

interventricular septum*

Partition that separates the right and left ventricles.

chordae tendineae*

What attaches the cusps of the valves to the papillary muscles in the heart?

pulmonary arteries

carry deoxygenated blood out of the right ventricle and into the lungs

bicuspid (mitral valve) *

located between the left atrium and left ventricle

left coronary a.

one of two arteries from the aorta that nourish the heart; (runs from left side of heart then divides into the circumflex and left anterior descending branches)

left atrium* and ventricle*

receives blood from pulmonary veins chambers that pump blood to body The systemic circuit includes the ____ mitral valve separates chambers that hold oxygenated blood

posterior interventricular a.

runs to the apex of the heart

marginal artery

supplies the right border of heart

pulmonary semilunar valve*

valve positioned between the right ventricle and the pulmonary artery; prevent back flow into the ventricles.

aortic semilunar valve*

where blood leaving the left ventricle passes through and into the systemic circuit via the ascending aorta; prevents back flow in the ventricle. (5)

tricuspid valve*

A valve that is situated at the opening of the right atrium of the heart into the right ventricle and that resembles the mitral valve in structure but consists of three triangular membranous flaps.

inferior vena cava*

A vein that is the largest vein in the human body and returns blood to the right atrium of the heart from bodily parts below the diaphragm.

superior vena cava*

A vein that is the second largest vein in the human body and returns blood to the right atrium of the heart from the upper half of the body.

pulmonary trunk*

Blood leaving the right ventricle enters this after passing through the pulmonary semilunar valve. gives rise to left and right pulmonary arteries
