Answer:
Blood Clot
The process of forming a clot or thrombus in order to prevent excess loss of blood from the body is called the clotting of blood. A jelly mass like substance is formed by the platelets and fibrin in the blood. Platelets play a vital role in the clotting of blood.
Given below is the flow chart representing the major steps involved in the process of clotting of blood:
Injury to blood vessel and platelets release prothrombin
⇓
Activation of prothrombin to thrombin
⇓
Splitting up of fibrinogen to fibrins by thrombin
⇓
A mesh is formed around the wound controlling RBC and platelets by fibers present in fibrins
⇓
Bleeding is stopped
⇓
The clot hardens and becomes smaller in size
⇓
New cells are grown to rebuild the wounded site
⇓
Plasmin enzymes are released and the clot is dissolved
