Blood supply and venous drainage of the heart wall Flashcards
by what veins is the blood drained from the coronary arteries in the heart?
The cardiac veins which drain into the coronary sinus which in turn drains into the right atrium.
where is the coronary sinus located?
posterior surface of the heart.
where do the coronary arteries and the cardiac veins lie together?
both the atrioventricular (coronary) sulcus and the inter ventricular sulci (grooves) of the heart wall.
Name the 6 coronary arteries.
right coronary artery
left coronary artery
anterior interventricular branch from left coronary artery
posterior inter ventricular branch of right coronary artery
circumflex branch of left coronary artery
Name the 6 cardiac veins.
great cardiac vein middle cardiac vein small cardiac vein anterior cardiac vein oblique vein of left atrium coronary sinus
which pair of coronary arteries anastamose in the coronary sulcus?
circumflex and right coronary artery
where does the right coronary artery distribute?
right atrium
right ventricle
atrioventricular node and bundle
sinoatrial node
where does the left coronary artery distribute?
both ventricles and the inter ventricular septum
left atrium
sinoatrial node
whats the name for the small veins which drain the heart wall directly into each chamber of the heart?
venae cordis minimae.
the great cardiac vein lies alongside what artery?
the anterior interventricular artery in the interventricular groove
the small cardiac vein lies along side what artery?
the marginal artery near the right inferior margin of the heart
the middle cardiac vein lies alongside what artery?
the posterior inter ventricular in the posterior inter ventricular groove
