Detailed explanation-1: -Clotting requires calcium ions (Ca2+), which is why blood banks use a chelating agent to bind the calcium in donated blood, so the blood will not clot in the bag.
Detailed explanation-2: -The network of fibrin covers the wound in which blood corpuscles get endulge and form clot. If ‘Ca^(2+)‘ is removed, it will prevent clotting.
Detailed explanation-3: -Explanation : Because clotting requires calcium ions (Ca2+), blood banks utilise a chelating chemical to bind the calcium in given blood, preventing it from clotting in the bag.
Detailed explanation-4: -How would removal of calcium ions from a blood sample affect coagulation? There would be no effect because calcium is not a necessary cofactor in coagulation.
Detailed explanation-5: -Hypocalcemia most commonly results when too much calcium is lost in urine or when not enough calcium is moved from bones into the blood. Causes of hypocalcemia include the following: A low level of parathyroid hormone (hypoparathyroidism.
