During blood clotting, in extrinsic pathway, thromboplastin activates:
Show Hint
Knowing the specific factors involved in each pathway of coagulation can aid in understanding clotting disorders and the effects of various anticoagulant medications.
Updated On: Mar 13, 2025
- Proconvertin
- Proaccelerin
- Hageman’s factor
- Prower factor
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
In the extrinsic pathway of blood coagulation, thromboplastin (tissue factor) is released by damaged tissues and combines with factor VII (proconvertin) to form a complex. This complex then activates factor X leading into the common pathway of coagulation. This step is crucial for the rapid response to vascular injury, initiating clot formation.
