Hemostasis
The stoppage of bleeding or hemorrhage.
Also, the stoppage of blood flow through a blood vessel or organ of the body.
Hemostasis is the arrest of bleeding, whether it be by normal vasoconstriction (the vessel walls closing temporarily), by an abnormal obstruction (such as a plaque) or by coagulation or surgical means (such as ligation).
The term comes from the Greek roots <I>heme</I>, blood + <I>stasis</I>, halt = halt of the blood.
