For the implementation of blood clotting, the following substances are required.

Blood clotting is a very important process for the survival of many animals. When injured, protective blood cells must be triggered to block blood loss. These cells are called platelets. When blood comes into contact with air, platelets are destroyed. They cause red blood cells to clump together. This is how blood clots are formed, which clog the blood vessels at the wound site and block the flow of blood. These properties of platelets are provided by the presence of fibrinogen, fibrinoplastic substance and thrombin in their composition.
