right coronary artery branches

marginal branch that travels along right ventricule
terminal posterior interventricular branch

32

posterior interventricular branch of right coronary artery
-has a...

capillary bed that overlaps the circumflex branch of the LCA

33

LAD
-termed the...
-also known as

widow maker
also known as L interventricular artery

34

venous drainage relation to arterial supply in heart

parallels it

35

veins of the heart

great cardiac vein
middle cardiac vein
small cardiac vein

36

where do the great cardiac vein and the middle cardiac vein lie

interventricular groove anterior and posterior, respectively

37

small cardiac vein parallels...

marginal branch of RCA

38

veins of the heart drain into...

cardiac sinus that lies in the right atrioventricular sulcus posteriorly
this drains into the right atrium

39

when are the coronary arteries covered

during systolic time frame of cardiac cycle

40

what happens to the coronary arteries at the beginning of diastole

ventricles begin to relax
elasticity of the aorta pushes blood back toward aortic valve

41

what occurs when the elasticity of the aorta pushes blood back toward the aortic valve

it mechanically closes the cusps of the valve
blood pools in the aortic sinuses of the left and right aortic cusps

42

function of elastic pressure of aorta during diastole

perfuses arterial blood into the coronary vessels
