Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel forming a blood clot. The process involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin. The coagulation cascade involves the activation of a series of clotting factors, the proteins involved in blood clotting.
Understanding the Context
Each clotting factor is a serine protease, an enzyme that speeds up the breakdown of another protein. Coagulation, in physiology, the process by which a blood clot is formed. The formation of a clot is often referred to as secondary hemostasis, because it forms the second stage in the process of arresting the loss of blood from a ruptured vessel. The coagulation proteins are the core components of the coagulation system that lead to a complex interplay of reactions resulting in the conversion of soluble fibrinogen to insoluble fibrin strands.

Key Insights
Coagulation is the formation of a blood clot, and is essential to haemostasis. Haemostasis is the body’s physiological response to damaged blood vessels, to slow down, minimise and eventually cease the bleeding. The meaning of COAGULATION is the process of becoming viscous or thickened into a coherent mass : the forming of clots (as in blood or cream) : the process of coagulating. Coagulation is considered as a cascade of proteolytic reactions, ultimately resulting in fibrin clot and thrombus formation. Its triggering occurs either by surface mediated reactions (intrinsic pathway) or through expression of tissue factor (TF) by cells (extrinsic pathway).

Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
