Solution
- The injured tissue cells and platelets disintegrate at the site of injury and release a substance known as thrombokinase or thromboplastin.
- The thrombokinase acts as an enzyme which converts prothrombin (inactive) of the plasma into thrombin (active), with the help of calcium ions present in the plasma.
- In the presence of calcium ions, the soluble fibrinogen of the plasma is converted to insoluble fibrin by thrombin.
- This fibrin forms a network of threads at the injury site.
- Along with RBCs, these threads make a trap to form a clot at the site of injury which prevents further bleeding.
