Besides, what does coagulation cascade mean?
1. The first is the physiological coagulation cascade, which is used to describe a very complex step-by-step process that occurs in the body (in vivo) when a blood vessel is injured. Several special proteins known as coagulation factors are activated one after the other in a "cascade" effect.
Also, what are the steps of coagulation? There are three steps to the process: vascular spasm, the formation of a platelet plug, and coagulation (blood clotting). Failure of any of these steps will result in hemorrhage—excessive bleeding.
Moreover, what are the 3 stages of blood clotting?
Hemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, in which clotting factors promote the formation of a fibrin clot. Fibrinolysis is the process in which a clot is degraded in a healing vessel.
What triggers coagulation?
The extrinsic pathway is activated by external trauma that causes blood to escape from the vascular system. This pathway is quicker than the intrinsic pathway. The intrinsic pathway is activated by trauma inside the vascular system, and is activated by platelets, exposed endothelium, chemicals, or collagen.
