Question

Quizplus · Accepted Answer

Significant loss of blood volume triggers the body's compensatory mechanisms to maintain blood pressure and perfusion to vital organs. This includes an increase in vascular tone (vasoconstriction) to elevate blood pressure, an increase in the secretion of antidiuretic hormone (ADH) to promote water reabsorption and increase blood volume, and an increase in heart rate to maintain cardiac output.
