The process of Blood Coagulation has three main stages, namely, Hemostasis or the formation of a gel-like substance at the site of injury to prevent further loss of Blood from taking place, thrombus formation as a result of platelets aggregation and the conversion of fibrinogen to fibrin, and clot retraction which is the contraction of the wound by smooth muscles to draw the edges closer together. Blood Coagulation is a process in which blood changes from a liquid to a semi-solid or solid state, which stops the bleeding from a wound.
