Neutrophils• percentage ranging between 50

and 70%,• distinguishable due to the number

ofLob es present in the nucleus, which can be up to a maximum of 5 granuls are small and spread samely in the cytoplasm

Eosinophil• Presentage :for the 1-5% in human blood• have predominantly rounded shape • dimensions around 10-12 microns, • have a nucleus with more lobes, but not greater than 2. • Nucluse bigger than neutrophil • Maimly thenucleus is in one side of the cell • Color of coffe bean granuls :from red to orang • They differ from other white blood cells for the presence

of granules,which include paracrystalline structures in the form of ”coffeebean”

lymphocyte• percentage of 20-45%• size of 7-15 microns,(smaller

than monocyte)• characterized by a rounded

nucleus and a cytoplasmPoor• Nucleus in dark

Monocytes• Larger member of W.B.C family • with a diameter of 12-18 microns• representing 3-9% of circulating

leukocytes.• Has one nucleus • Somethimes look brighter spot in

nucleus• Some sole in the nucleus

platelet• Size: larger than color particle • unregulary margin • Has some granules: serotonin, troboxan
