Solution
Solution: True.
Blood fails to clot readily in the case of deficiency of calcium because in one of the main reactions of blood clotting, calcium ions are required for the conversion of prothrombin to thrombin.
Without calcium ions this reaction will not occur and the blood clotting process will stop.
