Wikipedia
The sudden loss of blood that occurs during hemorrhage causes the cardiovascular system to change in several ways. The perfusion to various organs becomes compromised, leading to different compensatory mechanisms by the body to restore appropriate perfusion. The most immediate change is that the heart rate will increase as the body tries to get more blood to the vital organs. The blood pressure will also decrease, leading to hypoperfusion of the tissues, which means that insufficient oxygen and nutrients are getting delivered to the cells. Hemorrhage can cause organ damage and even death due to hypovolemic shock.
