Final answer:
The term for an excessive flow of blood is Hemorrhage, which is beyond the control of the body's hemostasis mechanisms and may require medical intervention to restore blood volume.
Step-by-step explanation:
The word that means an excessive flow of blood is d. Hemorrhage. Hemorrhage refers to the loss of blood that cannot be controlled by the body's natural hemostatic mechanisms. When a person experiences a hemorrhage, the body first tries to manage the situation by increasing blood pressure and maintaining blood flow to compensate for the lost volume. If the loss of blood is too great, medical intervention may be necessary to restore blood volume and prevent hypovolemic shock, which is a type of circulatory shock caused by excessive loss of blood volume.
