ECF volume _____ produces a(n) decrease in capillary hydrostatic pressure (Pc)

A negative inotropic agent causes the cardiac output to _____ and right atrial pressure to increase

AV shunts _____ preload and decrease afterload

The _____ valve closes slightly before the tricuspid valve, thus heart sound S1 may be split

During the early stages of exercise, cardiac output is maintained by increased _____ and stroke volume

Phase _____ of the myocardial action potential is characterized by initial repolarization

_____, or diastasis, is the longest phase of the cardiac cycle

The most important local metabolic factors for coronary circulation are _____ and adenosine (vasodilatory)

An increase in mean systemic pressure is reflected in a shift of the _____ function curve to the right

Resistance is _____ proportional to the length of the blood vessel
