Following hemorrhage,reflexes are triggered that attempt to compensate for the blood loss.As a result of the blood loss and the reflex mechanisms,which of the following will be TRUE,compared to pre-hemorrhage values?

Question

Quizplus · Accepted Answer

Hemorrhage will lead to a decrease in blood volume, resulting in a decrease in venous return and subsequent decrease in cardiac output. To compensate for the decrease in cardiac output, reflex mechanisms are triggered that cause an increase in total peripheral resistance (vasoconstriction) to maintain blood pressure. Therefore, compared to pre-hemorrhage values, cardiac output will be decreased and total peripheral resistance will be increased. Increase in hematocrit is not a direct consequence of hemorrhage and is not always observed.
