In the given flowchart, identify the A, B and C with respect to the blood clotting process.
A | B | C |
Thromboplastin | Prothrombin | Fibrinogen |
A | B | C |
Thrombin | Fibrinogen | Thrombokinase |
A | B | C |
Thromboplastin | Thrombin | Fibrinogen |
A | B | C |
Prothrombin | Thrombin | Fibrinogen |
In the process of blood clotting, thromboplastin is converted to thrombin, which is then converted to fibrinogen. Calcium also plays a crucial role in this process.
When there is an injury, thromboplastin is released with the help of calcium, it converts inactive prothrombin into active thrombin. Thrombin, in turn, converts fibrinogen into fibrin. Fibrin forms a mesh-like structure, which helps clot formation and stops bleeding at the injury site.
So, in summary, thromboplastin is converted to thrombin, which is further converted to fibrinogen, and calcium is essential for these conversions to occur.
Hence, the correct answer is option 3.
