Eosinophils

Eosinophils

a type of polymorphonuclear leukocyte containing eosin-staining granules. Although the activity of eosinophils is not entirely clear, they are known to destroy parasitic organisms and play a major role in allergic reactions. They also secrete chemical mediators that can cause bronchoconstriction in asthma. Eosinophils make up one to three percent of the total white blood cell count.
