neutrophil granulocyte
nucleus is divided into 3-5 lobes connected by thin strands of chromatin.
lobe number increases with cell age (old cells up to 7 lobes).
contain two types of granules.
- primary granules (A granules) contain lysosomal enzymes and are probably primary lysosomes, though they are larger (0.4 µm) than the typical primary lysosome.
- secondary granules (B granules), the specific granules of the neutrophils, contain enzymes with strong bactericidal actions. These granules stain only weakly if they are at all visible ("neutral").

eosinophil granulocyte
nucleus usually has only two lobes.
cytoplasm appears filled with the specific granules of the eosinophils.
granules are not neutral but stain red or pink when eosin dye.
contain some large rounded vesicles (up to 1 µm in diameter) in their cytoplasm.
granules (lysosomes) contain an electron-dense, proteinaceous crystal of major basic protein (MBP).

Blood Cells
Adult human blood cell numbers shown in the table below is for reference purposes. Blood Cell Numbers The adult ranges of cells / 1 litre (l), total blood volume is about 4.7 to 5 litres. Blood Development \| Blood Histology Red Blood Cells Male: 4.32 - 5.66 x 10¹²/l Female: 3.88 - 4.99 x 10¹²/l Leukocytes (white blood cells) Male: 3.7 - 9.5 x 10⁹/l Female: 3.9 - 11.1 x 10⁹/l Granulocytes 1.8 - 8.9 x 10⁹/l Neutrophils: 1.5 - 7.4 x 10⁹/l Eosinophils: 0.02 - 0.67 x 10⁹/l Basophils: 0 - 0.13 x 10⁹/l Non-Granulocytes Monocytes 0.21 - 0.92 x 10⁹/l Lymphocytes 1.1 - 3.5 x 10⁹/l B-cells: 0.06 - 0.66 x 10⁹/l T-cells: 0.77 - 2.68 x 10⁹/l CD4+: 0.53 - 1.76 x 10⁹/l CD8+: 0.30 - 1.03 x 10⁹/l NK cells: 0.20 - 0.40 x 10⁹/l Platelets 140 - 440 x 10⁹/l not a cell, a cell fragment.
