Hemorrhage with a Large Loss of Blood Causes ___________

Question

Hemorrhage with a large loss of blood causes ___________.
A) no change in blood pressure but a change in respiration
B) a rise in blood pressure due to change in cardiac output
C) a lowering of blood pressure due to change in cardiac output
D) no change in blood pressure but a slower heart rate

Accepted Answer

Hemorrhage leads to a significant loss of blood volume, which in turn reduces the cardiac output—the amount of blood the heart pumps through the circulatory system. This reduction in cardiac output causes a decrease in blood pressure, as there is less blood being circulated.
