Question:
Match the following lists regarding blood coagulation inhibitors and factors:
A) Heparin, B) Tissue thromboplastin, C) Warfarin, D) EDTA
(I) Antagonistic to Vit-K, (II) Binds to calcium ions, (III) Inactivates thrombin, (IV) Activates Proconvertin
Match the following lists regarding blood coagulation inhibitors and factors:
A) Heparin, B) Tissue thromboplastin, C) Warfarin, D) EDTA
(I) Antagonistic to Vit-K, (II) Binds to calcium ions, (III) Inactivates thrombin, (IV) Activates Proconvertin
Show Hint
Calcium is essential for clotting; remove it (EDTA) or block its effects to stop the cascade.

- A-III, B-IV, C-II, D-I
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Blood clotting factors and anticoagulant mechanisms.
Step 2: Analysis
* Heparin inactivates thrombin. * Tissue thromboplastin activates Proconvertin (Factor VII). * Warfarin is an antagonist to Vitamin K. * EDTA binds to calcium ions, preventing clotting.
Step 3: Conclusion
The correct matching is A-III, B-IV, C-I, D-II.
Final Answer: (C)
