A cut on your finger by a sharpener blade or a knife would have definitely caused a lot of pain but just some time later you� would have realised that the bleeding has stopped and some reddish substance is covering the wound that's called a clot But how is it made ?

�

As the blood flows out of the Wound, platelets ; one of the few residents of the bloods besides red blood cells, white blood cells, plasma ,Etc.� release a chemical thromboplastin. The calcium present in your blood combines with this chemical to form "protothrombin" Later form "thrombin" . Thrombin is basically a catalyst or� a substance that Eases the conversion of fibrinogen(present in your blood)� to fibrin.

�

Fibrin is a thread like substance which somewhat ties itself across the wound to form a net like structure to prevent for the further bloodloss. The red blood cells get trapped in this net made of a Fibrin which gives the red colour to the structure. This is a Clot.

�

Had This process not happened,� then a small injury would have led to fatal blood loss.

�

Another chemical "heparin" is somewhat an enemy of thrombus and inhibits it's action , but heparin is very important and life saving for people suffering from from the "THROMBIOSIS" - a condition in which unnecessary blood clotS, begin to form, hampering the blood flow in the blood vessels.
