The isolated heart and coronary circulation Flashcards
where do the coronary arteries arise
aortic sinus
when do coronary arteries have blood in them
diastole when the valves are shut
where does the left coronary artery pass
asses forward between the auricle of the left atrium and the pulmonary trunk and around to the left in the atrioventricular sulcus (groove)
describe the where the anterior inter-ventricular branch runs
runs in the anterior interventricular sulcus towards the apex of the heart.
It continues into the posterior interventricular sulcus on the diaphragmatic surface.
what does the LAD supply
supplies the anterior wall of the left ventricle and anterior two thirds of the interventricular septim
describe where the circumflex runs
which continues to the left in the atrioventricular sulcus to the posterior surface of the heart
what does the circumflex branch supply
left ventricle
describe where the right coronary artery runs
The right coronary artery leaves the right side of the ascending aorta and runs to the right in the atrioventricular sulcus
- On the posterior surface of the heart it turns down the posterior interventricular sulcus to become the posterior interventricular branch
what does the right marginal branch supply
right ventricle
the right marginal is smaller than the left as …
the wall of the right ventricle is thinner than that of the left ventricle.
what does the right coronary artery supply
the right coronary artery supplies the right atrium, the SA and the AV nodes and the posterior interventricular septum.
what does the PDA supply
posterior part of the ventricles
what is the main vein of the heart
coronary sinus
where does the great cardiac vein run
anterior interventricular sulcus
where does the small cardiac vein run
parallel to the right marginal artery
