Correct answer: D
Solution
(d) Basophils of white blood cells are connected with the release of histamine and the natural anticoagulant heparin. Basophils appear in many specific kinds of inflammatory reactions, particularly those that cause allergic symptoms. Basophils contain anticoagulant heparin, which prevents blood from clotting too quickly. They also contain the vasodilator histamine, which promotes blood flow to tissues. They can be found in unusually high numbers at sites of ectoparasite infection.More Body Fluids & Circulation PYQs
