E

Expert

Verified

Anticoagulants are substances that block the clotting reactions and thus stop the coagulation process. Ordinarily there are anticoagulants circulating in plasma because under normal conditions the blood should be kept fluid.

In Medicine anticoagulants like heparin are employed in surgeries in which tissue injuries made by the surgical act could trigger unwanted systemic blood clotting. They are also employed to circumvent the formation of thrombus in blood vessels of patients facing raised thrombotic risk.
