Hematology and Blood Disorders(CPD Accredited)

Hemostasis is the mechanism that indicates to cessation of bleeding from a blood vessel. It is a process that contains multiple interlinked steps. This cascade culminates into the development of a “plug” that closes up the damaged site of the blood vessel controlling the bleeding. It is the procedure of stopping or arresting bleeding or keeping the blood within the damaged blood vessel, particularly by physiological means such as vasoconstriction and coagulation or by surgical means.

The thrombosis is a formation or occurrence of a blood clot in a blood vessel. The vessel may be any vein or artery as, for instance, in a deep vein thrombosis or a coronary (artery) thrombosis. The clot itself is characterized a thrombus. If the clot breaks unattached and travels through the bloodstream, it is a thromboembolism. Thrombosis, thrombus, and the prefix thrombo- all arise from the Greek thrombo meaning a lump or clump, or a curd or clot of milk.
