Hemostázisra

Hemostázisra, which translates to hemostasis in English, refers to the process by which bleeding is stopped. This intricate physiological mechanism involves a complex interplay of blood vessels, platelets, and coagulation factors. When a blood vessel is injured, the body initiates a rapid response to prevent excessive blood loss. Initially, the damaged vessel constricts, reducing blood flow to the injured site. Concurrently, platelets circulating in the blood adhere to the damaged area, forming a temporary plug. This platelet plug is then reinforced by a fibrin clot, which is formed through a cascade of enzymatic reactions involving specific proteins known as coagulation factors. This fibrin mesh traps blood cells and further solidifies the plug, effectively sealing the injured vessel and initiating the healing process. Hemostasis is a vital process for survival, preventing significant blood loss from even minor injuries. Disruptions to this delicate balance can lead to either excessive bleeding (hemorrhage) or unwanted clot formation (thrombosis), both of which can have serious health consequences.
