Answers
Answer:

heparin is a natural anticoagulant present in blood cells which automatically prevent the loss of blood.
Blood Clotting-
The conversion of liquid blood into a jelly form when blood vessels are damaged is called clotting of blood.
It involves the conversion of a soluble protein,i.e., fibrinogen into an insoluble fibrous protein called fibrin.
Blood clotting not only prevents the loss of blood but also the entry of any disease-causing germs at the site of injury.
Prevention-
Blood clotting can be prevented by adding anticoagulants such as citric acid and oxalic acid in blood.
These substances precipitate the calcium salts present in plasma. Because of the property, blood can be preserved for a long time in blood donation centres and can be later used for transfusion in case of an emergency.
