Clotting of blood refers to the process of forming a clot or thrombus in order to prevent excessive blood loss from the body.
Platelets and fibrin in the blood combine to form a gel-like substance. Platelets are critical components of blood clotting.
Blood clotting usually occurs when a blood vessel is damaged. Platelets begin to accumulate at the vessel's cut edges and release chemicals that attract more platelets.
When a blood vessel is injured, blood clotting/coagulation is an important process that prevents excessive bleeding.
The following are some key events in blood clotting:
Prothrombin is released by wounds to blood vessels and platelets.
After that, prothrombin is converted to thrombin
The conversion of fibrinogen to fibrin by thrombin.
A trap forms around the wound, which is controlled by RBC and platelets via fibrin fibers.
