coronary artery

Function: - the coronary arteries supply blood to the heart - blood flow is maximal during diastole. Origin: - their origins are at the base of the aorta, within the right & left aortic sinuses just above the aortic valve Anastomoses: - anastomoses between branches of the major coronary arteries under normal circumstances is small, but may increase substantially in number & size in patients with severe stenosis of a major coronary vessel. Pathology: - occlusion of the coronary arteries occurs in coronary artery disease Special lahoratory: - patency of the coronary arteries is assessed by cardiac catheterization & coronary angiography.
