Which type of white blood cells are concerned with the release of histamine and the natural anti-coagulant heparin?
A
Eosinophils
B
Monocytes
C
Neutrophils
D
Basophils
Detailed Solution
Basophils are the least abundant white blood cells, forming only about 0.5 to 1 percent of the total leucocytes.
They are granulocytes whose granules stain with basic dyes.
Basophils secrete histamine, serotonin and heparin, and are involved in inflammatory reactions.
Histamine dilates the blood vessels during inflammation and allergic reactions, and heparin is a natural anti-coagulant that prevents the clotting of blood inside the vessels.
Eosinophils resist infections and are associated with allergic reactions, while neutrophils and monocytes are phagocytic cells.
So the cells concerned with the release of histamine and heparin are the basophils.
