Where does blood enter the myocardium?
Oxygenated blood is brought to the myocardium by coronary arteries. These arteries are located all around he surface of the heart.
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.
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.
The left side of the heart is much bigger and stronger because it must pump blood through out to the entire body. The right side of the heart must only pump blood through the lungs (and then to the left side). So, since the blood is pumped in through and out of the left side with more pressure, the myocardium must be thicker.
Which surgical procedure is done toprovide the myocardium with a new source of blood supply when a coronary artery is occluded?

Vena Cava returns blood to the right atrium. That is true. There are at least two more vessels in addition to the Superior and Inferior vena cavae: The coronary sinus: Returns venous blood from most of the myocardium The anterior cardiac veins: Return venous blood from the right anterior portion of the myocardium
The myocardium is part of the most superficial layer of the heart. It is the middle of these three. The myocardium forms the bulk of the heart, and it consists mainly of cardiac muscle. This is the layer that sactually contracts. The myocardium's elongated, circularly and spirally arranged networks of cardiac mucle cells squeeze blood through the heart in the proper directions.
The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the myocardium (Cardiac muscle). The myocardium contracts after stimulation. It is the ordered stimulation of the myocardium that allows efficient contraction of the heart, thereby allowing blood to be pumped throughout the body.
