Coronary
Circulation:

As opposed to the systemic circulatory system
(which provides blood to all organs other than the heart), the coronary system provides
blood to the heart itself.  The right and left coronary arteries arise as openings at
the base of the right and left cusp of the aortic valve in the form of ostia…the right
and left coronary ostia.  The left main coronary artery gives off the left anterior
descending (LAD) coronary artery with passes down along the anterior aspect of the left
ventricle.  It also gives rise to the left circumflex coronary artery that passes
posteriorly.  The right main coronary artery passes around the right upper portion of
the heart and gives rise to the posterior descending branch that passes down the
posterior aspect of the right ventricle.

The
commonest sites of coronary artery occlusion (obstruction) leading to heart attacks are
the proximal right coronary artery (usually s few centimeters from the right coronary
ostium), and the proximal LAD (usually about one or two centimeters below or distal to
the LAD’s origin from the left main coronary artery).  Coronary occlusions occur at the
sites where there has been a build-up of arteriosclerotic plaque.  They can be from
coronary thrombosis (clotting at the plaque site) or spasm of the
vessel.

Systemic Circulation:  As opposed to the
coronary circulation the systemic circulation constitutes the circulation to the entire
body other than the heart.  It begins after the aortic valve where blood has left the
heart, and ends in the superior and inferior vena cavae that bring deoxygenated blood
from the organs back to the
heart.

Summary:

The
heart pumps blood through the coronary circulation to supply oxygen to the heart itself,
and through the systemic circulation to supply the entire body other than the
heart.
