WebbHemostasis 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. Anticoagulants are substances that oppose coagulation.

WebbPlatelets contain a number of compounds involved in blood clotting. These are the so-called platelet (platelet) factors. The most important among them are: factor 3 (platelet thromboplastin). This is a phospholipid, which is released during the destruction of platelets and is used as a matrix for reactions in the I phase of coagulation.

WebbClot retraction is caused by normal or hyperactive platelet function and measured in vitro by measuring the volume of serum extruded from the clot or a decrease in size of the clot mass [67].

The mechanism of hemostasis can divide into four stages. 1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug." 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.
