MEDICAL PHYSIOLOGY

Detailed explanation-1: -Hemostasis is the mechanism that leads to cessation of bleeding from a blood vessel. It is a process that involves multiple interlinked steps. This cascade culminates into the formation of a “plug” that closes up the damaged site of the blood vessel controlling the bleeding.

Detailed explanation-2: -Hemostasis is the arrest of bleeding, whether it be by normal vasoconstriction (the vessel walls closing temporarily), by an abnormal obstruction (such as a plaque) or by coagulation or surgical means (such as ligation). The term comes from the Greek roots heme, blood + stasis, halt = halt of the blood.

Detailed explanation-3: -The main job of platelets, or thrombocytes, is blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding.

Detailed explanation-4: -Haemostasis is the physiological process by which bleeding ceases. Haemostasis involves three basic steps: vascular spasm, the formation of a platelet plug, and coagulation, by which clotting factors promote the formation of a fibrin clot.
