The myocardium receives its blood supply from the?
The myocardium receives blood from the coronary arteries.
The myocardium is the muscle of the heart. This muscle is supplied by arteries that branch off the aorta. So everytime the heart beats it pushes blood into the aorta and thus into systemic circulation and thus into the heart wall, as well. These arteries that supply the myocardium are called coronary arteries.
Deficient blood supply to the myocardium is: ischemia Ischemia is the medical terms for deficient blood supply to the myocardium. The suffix -emia denotes a blood condition; ischem/o means to hold back. With occlusion from atherosclerosis, the blood flow is restricted, resulting in deficient blood supply.
