Quizplus · Accepted Answer

A) In the normal heart, during exercise, coronary blood flow increases to meet the increased demand for oxygen and nutrients by the heart.
B) In a diseased heart, the blood vessels supplying the heart may become narrowed or blocked, which can reduce the blood flow to the heart muscle, causing ischemia and angina. Thus, in some cases, the coronary blood flow may be maximal at rest.
C) Due to the insufficient blood flow to the heart muscles during exertion, the heart may not receive enough oxygen and nutrients, leading to ischemia and angina. 
Therefore, all the above choices are true regarding cardiac blood flow.
