Coronary arteries (where do they supply blood to?)

[Eirene, ASN, RN]

hey guys! i really know the general answer to this question; but...

we were given a "little" homework assignment to have completed for our first alterations in cardiac functioning on thursday. this is what the paper says:

coronary arteries (where to they supply blood to?)

right coronary artery (rca) serves ______ (1) node

right atrium and ventricle; post. wall left ventricle

left coronary (lca)- serves

left anterior descending

intraventricular suptum and anterior _______ (2) ventricle

circumflex artery

left _______ (3) and lateral portion of _____ (4) ventricle

coronary veins

drain the myocardium

empty into the _____ (5) atrium

i feel all kinds of silly that i don't remember this and can't seem to find the information. i'm trying to remember from a & p and so far i have:

1. sa (sino-atrial)

4. left ventricle

5. right atrium

if anyone could help me on this, i'd really appreciate it.

thanks,

dani
