Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) Correct Answers A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known...

BSNC 6000 Module 1 Midterm Review Questions What are the effects of hypertension on macrocirculation? - Answer--Hypertension causes injury to the endothelial layer of the arteries which leads to plaque formation. Plaque restricts blood flow and can lead to ischemia. Plaque also weakens artery walls thereby increasing the risk of an aneurysm -Hypertension increases resistance to blood flow to the tissues. As a result, the heart pumps harder to overcome the resistance. A chronic increase in the...
