Verenhyytymistekijät
Verenhyytymistekijät, also known as coagulation factors, are a group of proteins circulating in the blood plasma that are essential for hemostasis, the process by which bleeding is stopped. When a blood vessel is injured, these factors are activated in a cascade, a series of enzymatic reactions where each factor activates the next. This cascade culminates in the formation of a fibrin clot, a mesh-like structure that seals the injured vessel and prevents further blood loss.
There are numerous coagulation factors, each designated by a Roman numeral, from I to XIII, although some
The coagulation system is tightly regulated to prevent excessive clotting (thrombosis) or insufficient clotting (bleeding disorders).
