Vedclass · Answer

(A) Leeches belong to the phylum $Annelida$ and the class $Hirudinea$.They secrete a potent anticoagulant substance known as $Hirudin$ from their salivary glands.$Hirudin$ prevents blood coagulation by inhibiting the enzyme $Thrombin$,which is essential for the conversion of fibrinogen to fibrin during the blood clotting process.This allows the leech to feed on the host's blood continuously without the blood clotting at the site of the bite.
