What is the function of coronary circulation (also known as the coronary circuit)?
Functions Of Coronary Circulation :
Coronary Arteries :
It supplies the oxygenated blood to the heart.
It arises from the ascending aorta and divided in to left and right
coronary branches.
i)The left coronary artery:
The left coronary artery pass inferior to left aurcle an divided in
to the anterior interventricular and circumflex branches.
The anterior interventricular branch or left anterior
descending(LAD)
arteries enter in to the anterior interventricular sulcus and
supplies oxygenated blood to the walls of both ventricles and the
interventricular septum.
The circumflex branch lies in the coronary sulcus and distributes
oxygenated blood to the walls of the left ventricle and left
atrium.
ii)The right coronary artery:
The right coronary arters branches supply blood to the right
atrium.
It continues inferior to the right auricle and divided in to the
posterior interventricular marginal branches.
The posterior Interventricular branches enter in to the posterior
interventricular sulcus and supply the oxygenated blood in to
two
ventricles and the interventricular septum.
The marginal branch in the coronary sulcus transports oxygenated
blood to the myocardium of the right ventricle.
