The Renin-Angiotensin-Aldosterone System Compensates for Hypovolemic Shock by Stimulating

The renin-angiotensin-aldosterone system compensates for hypovolemic shock by stimulating:

A) antidiuretic hormone from the posterior pituitary to retain potassium and excrete sodium to improve myocardial contractility.
B) ß1-adrenergic receptors to increase myocardial contractility, heart rate, and conduction through the atrioventricular node.
C) aldosterone release, which retains sodium and hence water to increase the blood volume.
D) movement of calcium into vascular smooth muscle, causing vasoconstriction and increasing systemic vascular resistance.
