Thrombus
A thrombus, or blood clot stops bleeding. It keeps blood inside a damaged blood vessel, and stops the hemorrhage.

A blood clot is the final product of the coagulation. There are aggregated platelets and red blood cells. Together with fibrin they form a plug, and stop the bleeding.
The substance making up a thrombus is sometimes called cruor.
A thrombus is a healthy response to injury to prevent bleeding, but can be harmful in thrombosis, when clots block blood flow through otherwise normal blood vessels.[1][2]

Animation of the formation of an occlusive thrombus in a vein. A few platelets attach themselves to the valve lips, constricting the opening and causing more platelets and red blood cells to aggregate and coagulate. Coagulation of unmoving blood on both sides of the blockage may propagate a clot in both directions.
