what are the two grooves of the heart
atrioventricular groove (coronary sulcus)
interventricular groove
what two arteries arise from the ascending aorta just distal to the aortic valve
R coronary artery (RCA)
L coronary artery (LCA)
is the LCA or RCA SHORTER
the LCA is shorter
the RCA and LCA travel in which groove
atrioventricular groove (coronary sulcus)
which artery is the proximal branch of the RCA and travels to the SVC deep to the right auricle
sinoatrial nodal artery
which artery travels towards the apex of the heart
right marginal artery
on the posterior aspect of the heart, where is the RCA
still in the AV groove
which artery is located in the IV groove and anastomoses with the anterior interventricular artery
posterior interventricular artery
why is the LCA so short
it bifurcates early, near the pulmonary trunk
the LCA bifurcates into
circumflex branch of the LCA
anterior interventricular artery
in which groove does the circumflex branch of the LCA travel
AV groove
in which groove does the anterior interventricular artery travel and what does it anastomose with
IV groove, posterior interventricular artery
which artery is a branch of the circumflex branch of the LCA
left marginal artery
the circumflex branch of the LCA travels with _____ ______ in AV groove on posterior aspect of heart
coronary sinus
the coronary sinus is located within the ___ groove on the _____ aspect of the heart and received venous blood from
AV, posterior, most veins of the heart
which vein is the main tributary of the coronary sinus and conveys venous blood to the left side of the coronary sinus
great cardiac vein
which vein travels with the posterior IV artery
middle cardiac vein
which vein travels with the RCA and right marginal artery
small cardiac vein
travel buddies of the heart (5)
coronary sinus + circumflex branch of LCA
middle cardiac vein + posterior IV artery
small cardiac vein + RCA on posterior
small cardiac vein + right marginal artery on anterior
great cardiac vein + anterior IV artery
