what are the coronary arteries?
a network of progressively smaller vessels that carry oxygenated blood to the myocardium
what do the coronary arteries arise from?
the ascending aorta just beyond where the aorta leaves the left ventricle
what are the coronary arteries and their main branches responsible for supplying blood to?
the myocardium
the myocardium receives blood from the __ __ and their __ __
coronary arteries and their main branches
what are the two main coronary arteries?
right and left coronary arteries
right coronary artery main branches (3)
sinus node artery
right marginal artery
posterior descending artery
sinus node artery
main branch of right coronary artery that supplies the right atrium
what main branch of the right coronary artery supplies the right atrium?
sinus node artery
right marginal artery
main branch of the right coronary artery that supplies the right ventricle
what main branch of the right coronary artery supplies the right ventricle?
right marginal artery
posterior descending artery
main branch of the right coronary artery that supplies the inferior walls of both ventricles and the interior portion of the interventricular septum
what main branch of the right coronary artery supplies the inferior walls of both ventricles and the inferior interventricular septum?
posterior descending artery
left coronary artery main branches (2)?
circumflex artery
left anterior descending artery
circumflex artery
main branch of the left coronary artery that supplies the left atrium, posterior, lateral, anterior and inferior walls of the left ventricle
what main branch of the left coronary artery supplies the left atrium as well as the anterior, posterior, lateral and inferior walls of the left ventricle?
circumflex artery
left anterior descending artery
main branch of the left coronary artery that supplies the anterior portion of the interventricular septum
what main branch of the left coronary artery supplies the anterior portion of the interventricular septum?
left anterior descending artery
what does the coronary venous circulation include?
coronary sinus
cardiac veins (great cardiac vein, small cardiac vein, middle cardiac vein)
thesbian veins
what do the cardiac veins of the coronary venous circulation include?
great cardiac vein
small cardiac vein
middle cardiac vein
what do the cardiac veins of the coronary venous circulation drain into into?
coronary sinus, emptying into the right atrium
where do the thesbian veins of the coronary venous circulation arise from?
the myocardium
where do the thesbian veins drain into?
all parts of the heart, but primarily into the right atrium and right ventricle
