Intrinsic Pathway: The intrinsic pathway, also called the contact activation pathway, is one of the two main pathways of the blood coagulation cascade. It is initiated by the activation of factor XII upon contact with damaged or foreign surfaces.
Hemostasis: Hemostasis is the process by which the body stops bleeding, either at the site of an injury or through a break in a vessel. It involves a complex series of events, including platelet activation, the coagulation cascade, and the formation of a stable fibrin clot.
Coagulation Cascade: The coagulation cascade is a series of enzymatic reactions that lead to the formation of a fibrin clot, which helps to stop bleeding. It consists of the intrinsic and extrinsic pathways, both of which converge on the common pathway.
