Answer:
Removal of calcium from freshly collected blood wound prevents clotting of blood.
Explanation:
Along with proteolytic enzymes thrombin and fibrin blood also requires calcium ions for clotting.
If one one removes calcium from the freshly collected blood the blood looses the ability to clot as the clotting reactions doesn't occur in absence of calcium ions.
Thus clotting is prevented.
This method is usually implied in blood banks.
