Document Summary

T or f: cardiac output is blood volume ejected in 1 second. Left ventricular end-diastolic volume: amt of ventricular stretch at end diastole. Systemic vascular resistance (svr): amt of resistance the heart must overcome to open aortic valve and push blood out to systemic. Determined by: resistance of arteries to blood flow.

T or f: progression of atherosclerosis is a long and slow process. T or f: atherosclerosis only happens in coronary arteries. Root of aorta right coronary artery & left coronary artery. Connections b/w small branches of r & l coronaries to provide collateral circulation if a main branch was blocked. Arterio = wall thickening narrowing lumen obstruction decr. blood flow. Athero = most common form of arteriosclerosis: accumulation of fatty plaques (athromas) in the artery.
