Question

Quizplus · Accepted Answer

The body responds to hemorrhage by trying to maintain blood pressure and perfusion to vital organs. This is achieved through increasing the sympathetic nervous system activity, which causes vasoconstriction and an increase in heart rate and contractility. The aim is to keep mean arterial pressure to levels approaching but below normal. A decrease in heart rate and total peripheral resistance, as well as an increase in cardiac output, would not be able to compensate for the loss of blood volume and maintain blood pressure, therefore are not correct options.
