This Blood Clotting Process Diagram depicts an important process that prevents excessive clotting if a blood vessel is injured. It is essential in the repair of blood vessels. Clotting factors are components of plasma that are involved in the clotting process. These factors are named and numbered in the order in which they were discovered. Platelet formations are also depicted in this Blood Clotting Process Diagram. Blood clotting usually occurs when a blood vessel is damaged. Platelets immediately adhere to the vessel's cut edges and release chemicals that attract additional platelets. The formation of a platelet plug stops the external bleeding.
