Document Summary

Systemic circuit: long pathway with 5x resistance(left ventricle) Coronary circulation is the circulation of blood in the blood vessels of the heart. Coronary arteries: the vessels that deliver oxygen-rich blood to the myocardium. Cardiac veins: the vessels that remove the deoxygenated blood from the heart muscle. The blood supply to the heart is greater than that of other body tissues since the heart has a constant metabolic demand that must be satis ed to keep the heart pumping at all times. Epicardial coronary arteries: run along the surface of the heart and are capable of auto regulating vasodilation and vasoconstriction to maintain coronary blood ow at appropriate levels to t the metabolic demands of the heart muscle. Subendocardial coronary arteries: run deep within the myocardium to provide oxygen through the muscle tissue of the cardiac wall. ***systole is the contraction of the heart(pumping out) and diastole is the relaxation of the heart( lling).
