Coagulation Factors and Pathways

This video tutorial covers the 13 clotting factors, explaining each factor's role and source. It highlights that factor six is missing and provides detailed information on factors one through thirteen, including fibrinogen, prothrombin, thromboplastin, calcium, and others. The video concludes by encouraging viewers to watch the next part, which focuses on coagulation pathways.

How many clotting factors are there, excluding the missing one?

• 11

• 12

• 13

• 14

What is the source of fibrinogen?

• Kidneys

• Liver

• Spleen

• Bone marrow

Which factor is known as the prothrombin?

• Factor 1

• Factor 2

• Factor 3

• Factor 4

What is the role of calcium in the coagulation pathways?

• Involved in most reactions of both pathways

• Stabilizes fibrin

• Converts fibrinogen to fibrin

• Initiates the extrinsic pathway

Why is Factor 6 unassigned?

• It was previously known as activated Factor 5

• It was never discovered

• It is a duplicate of another factor

• It is not involved in coagulation

Which factor is known as the Christmas Factor?

• Factor 7

• Factor 10

• Factor 8

• Factor 9

What is the source of Factor 10?

• Kidneys

• Bone marrow

• Spleen

• Liver

Which factors are involved exclusively in the intrinsic pathway?

• Factors 1, 2, 3

• Factors 4, 5, 6

• Factors 9, 11, 12

• Factors 7, 8, 10

What is the role of Factor 13 in coagulation?

• Initiates the intrinsic pathway

• Converts fibrinogen to fibrin

• Stabilizes fibrin monomers

• Activates prothrombin

What happens to fibrin monomers without Factor 13?

• They dissolve in plasma

• They convert back to fibrinogen

• They initiate the extrinsic pathway

• They remain weakly bound
