Haemostasis  is the normal spontaneous arrest of bleeding from ruptured blood vessels. Normal haemostasis depends on a combination of events: the vascular response, which occurs mainly at capillary and small vessel level, the platelet (or thrombocyte) response, which also occurs in capillaries and small vessels, and the blood coagulation response which takes place in the arteries and veins.

* The blood coagulation process is beneficial, as it is designed to minimise blood loss.
