Quizplus · Accepted Answer

In response to hemorrhage, the body initiates compensatory mechanisms to maintain blood pressure and blood flow to vital organs. Peripheral vasoconstriction (A) occurs to increase vascular resistance and maintain blood pressure. Mobilization of the venous reserve (C) helps increase venous return to the heart, supporting cardiac output. Increased parasympathetic stimulation (B) would decrease heart rate, which is not a typical response to hemorrhage.
