A type of white blood cell or leukocyte which stains a red color with eosin stain; normally about 2 to 3 percent of white cells in the blood but tending to decrease during stressful situations and thus usable as an index for stress
1-3% of leukocytes - Phagocytes that destroy parasites either by engulfing them or by attaching to them and releasing enzymes that destroy the parasites Such chemicals are implicated in allergic reactions, especially bronchorestriction in asthma
White blood cells that make up 0-5% of all white blood cells Eosinophils are involved in allergic responses Normal range = up to 0 5
are a type of granulocytes They destroy parasitic organisms and play a major role in allergic reactions (hypersensitivity) They also secrete chemical mediators that can cause bronchoconstriction in asthma
a type of white blood cell that can increase with allergies, asthmas, and infections
Granular leukocytes with a nucleus that usually has two lobes connected by a slender thread of chromatin, and cytoplasm containing coarse, round granules that are uniform in size and stainable by eosin
