During an injury, the blood platelets release thromboplastin which converts plasma protein prothrombin into thrombin in the presence of calcium ions. Thrombin then converts soluble plasma protein fibrinogen into fibrin which forms a meshwork by trapping red blood cells, thus forming a clot.

The process of blood clotting is known as coagulation and it is a complex series of events that involves various blood components. When body tissues are injured resulting in the loss of blood, the process of blood clot begins. In this process, the damaged tissue releases a substance called thromboplastin that initiates the clotting cascade.
The blood platelets play a crucial role in the blood clotting process. They release several factors that help in clot formation. One of these factors is thromboplastin.
Explanation of Options:
- Prothrombin: It is a protein that is produced in the liver and is converted to thrombin during the clotting cascade. It is not released by blood platelets.
- Thromboplastin: It is a substance that is released by damaged tissue and initiates the clotting cascade. It activates prothrombin to thrombin.
- Thrombin: It is an enzyme that converts fibrinogen to fibrin, which forms the basis of the blood clot.
- Fibrinogen: It is a protein that is converted to fibrin during the clotting cascade. It is not released by blood platelets.
Therefore, the correct answer is option B, thromboplastin, as it is released by damaged tissue and initiates the clotting cascade.
