Platelets help in clotting of blood. There are 13 different factors which affect the clotting mechanism. A clot is a reddish brown scum made up of fibre like structures known as fibrins. The important steps in clotting mechanism can be explained below:-
Step-1:- release of thromboplastin from injured tissues & platelets
Step-2:- This thromboplastin helps in the formation of a complex enzyme thrombokinase.
Step-3:- this thrombokinase converts prothrombin into active thrombin
Step-4:- This thrombin converts soluble fibrinogen into insoluble fibrin.
Step-5:- This fibrin forms a network at the site of injury which traps the blood & form clot.
