Question

Menstrual blood does not clot due to the presence of ?

• A. Prothrombin
• B. Fibrinogen
• C. Fibrinolysins
• D. Thromboplastin

Hint:

Fibrinolysins are enzymes that dissolve fibrin, preventing blood clot formation. Their role is crucial in maintaining proper flow in specific biological processes like menstruation.

Answer 1

The Correct Option is C

Menstrual blood typically remains liquid due to fibrinolysins, enzymes that degrade fibrin, a key component of clot formation. Consequently:

• The blood maintains a fluid consistency.
• This action inhibits clot development within the uterine lining during menstruation.

This physiological process facilitates unimpeded menstrual blood flow, preventing clot formation under normal circumstances.
