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 does not clot because of the presence of fibrinolysins. These enzymes are responsible for breaking down fibrin, which is essential for clot formation. As a result:

• The blood remains in a fluid state.
• This prevents clot formation within the uterine lining during menstruation.

This mechanism ensures that the menstrual blood flows smoothly without forming clots under normal physiological conditions.
