substance in blood and tissues which, in the presence of ionized calcium, aids in the conversion of prothrombin to thrombin. Extrinsic and intrinsic thromboplastin are formed as the result of the interaction of different clotting factors; the factors that combine to form extrinsic thromboplastin are not all derived from intravascular sources, whereas those that form intrinsic thromboplastin are.
why there may be large quantities of thromboplastin in blood after surgery.

Thromboplastin -> Prothrombin -> Thrombin -> Fibrinogen -> Fibrin
Thromboplastin, also known as tissue factor, is produced by subendothelial cells in blood vessel walls and by blood cells called monocytes and macrophages. Upon injury to a blood vessel, thromboplastin is exposed and initiates the extrinsic pathway of blood coagulation.

A test to check your blood clotting.
In the final step of blood clotting cascade, Thromboplastin activates the prothrombin to Thrombin. Then the activated thrombin helps in the conversion of Fibrionogen into Fibrin (Mesh like fibrils which forms the clot).
Thromboplastin and PF3 interact to form a complex that activates the enzyme thrombin. This activation cascade is a crucial step in the blood clotting process, leading to the formation of a stable fibrin clot.
Thromboplastin, also known as tissue factor, is released from damaged tissues and activated endothelial cells in response to injury. When blood vessels are damaged, the exposure of collagen and other underlying structures triggers the release of thromboplastin into the bloodstream. This protein then interacts with factor VII to initiate the extrinsic pathway of coagulation, ultimately leading to the formation of a blood clot.
