Module 12 Cardiovascular System Overview

Diuretics are good medications for the management of hypertension and heart failure because of which of the following mechanisms?

• 
  Promote sodium depletion, decreasing intravascular volume

• Inhibit angiotensin converting enzyme, preventing vasoconstriction

• Block alpha receptors in the blood vessels, lessening vascular tone

• Dilate blood vessels, decreasing vascular pressure
