Detailed explanation-1: -Hemostasis refers to normal blood clotting in response to an injury. However, your body can also have too much clotting, known as hypercoagulability. That can cause many blood clots to form spontaneously and block normal blood flow. When blood clots form inside your blood vessels, this is known as thrombosis.
Detailed explanation-2: -Hemostasis is the cessation of bleeding from a cut or severed vessel, whereas thrombosis occurs when the endothelium lining blood vessels is damaged or removed (eg, upon rupture of an atherosclerotic plaque).
Detailed explanation-3: -Definition. 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-4: -While hemostasis represents a physiological response to prevent bleeding, the term thrombosis typically refers to the pathologic formation of a thrombus (clot).
Detailed explanation-5: -Vasoconstriction. Intact blood vessels are central to moderating blood’s clotting tendency. The endothelial cells of intact vessels prevent clotting by expressing a fibrinolytic heparin molecule and thrombomodulin, which prevents platelet aggregation and stops the coagulation cascade with nitric oxide and prostacyclin.
