Answer to Question 1

ANS: C
The primary cardiovascular control center is in the brainstem in the medulla. The cerebral cortex, the thalamus, and hypothalamus are secondary control sites.

Answer to Question 2

ANS: B
The Frank-Starling law of the heart describes the length-tension relationship of ventricular end-diastolic volume (VEDV) (preload) to myocardial contractility (as measured by stroke vol-ume). It does not refer to duration, pressure, or viscosity.
