Eosinophil granulocyte
Eosinophils make up 1-6% of white blood cells circulating in the body. They are similar in size to neutrophils but have reddish-orange granules (when stained with eosin) and a bilobed nucleus. Eosinophil granulocytes are important defenders against large, multi-cellular parasites, such as worms and flukes. Their numbers increase during a parasitic infection.
