Question

Which of the following factors are used in the blood coagulation/blood clotting process?

• A. Fibrin, Fibrinogen, Thrombin, Prothrombin, Thromboplastin
• B. Prothrombin, Thromboplastin, Thrombin, Fibrin, Fibrinogen
• C. Thromboplastin, Thrombin, Prothrombin, Fibrin, Fibrinogen
• D. Thromboplastin, Prothrombin, Thrombin, Fibrinogen, Fibrin

Answer 1

Answer: (A), (B)

The correct options are
A

Fibrin, Fibrinogen, Thrombin, Prothrombin, Thromboplastin

B

Prothrombin, Thromboplastin, Thrombin, Fibrin, Fibrinogen

When the blood vessels are damaged they attract platelets. The damaged endothelial cells express tissue factor. The tissue factor initiates a coagulation cascade.The main factors that are used in the process of blood coagulation are fibrin (inactive form is fibrinogen) and another factor is thrombin (inactive form is Prothrombin).
