Document Summary

Terms: cardiac output; preload, afterload, atheromas, hdl, ldl. Cardiac output blood ejected by a ventricle in 1 minute. Preload amount of blood delivered to heart by venous return. Afterload force required to eject blood from ventricles. Atheroma - the fatty material that forms plaques in the arteries. Fatty deposits building up, restricting the blood flow through the artery. Low-density lipoprotein (ldl) (cid:862)(cid:271)ad(cid:863) (cid:272)holesterol: transports cholesterol from liver to cells, major factor contributing to atheroma formation. High-density lipoprotein (hdl) (cid:862)good(cid:863) (cid:272)holesterol: transports cholesterol away from the peripheral cells to liver (cid:862)good(cid:863) lipoprotei(cid:374, catabolism in liver and excretion. Insufficient oxygen/blood supply to the myocardial (heart muscle).
