A blood clot forms when blood cells and fibrin strands clump together. A clot that blocks blood flow is called a thrombus.
flow chart :
injured tissues and platelets release the clotting factor prothrombin activator and calcium ions.
↓
prothrombin activator converts the blood protein prothrombin to thrombin.
↓
Thrombin splits fibrinogen to form fibrin.
↓
Fibrin fibers form a mesh over wound, trapping red blood cells and platelets.
↓
Bleeding stop
↓
Clot hardens and becomes smaller.
↓
New cells grow to repair wound site.
↓
Enzymes plasmin is released to dissolve clot.
