Rbc are highly specialized for this transport function each cell cont. To maintain these quantities of rbc, body has to produce new mature. Characterized mainly on the shape of the nucleus: 2-6 lobes (usually 3) each lobe connected by thin strands or filaments of the nuclear material. In addition, nuclear appendages taking on a variety of shapes may be present. condensed chromatin. Barr body (drumstick) in females only with significant represents sex chromatin. Small small pinkish staining granules contains lysosomal enzymes and bactericidal compounds abundant granules phagocytic outside of the blood first line of defense against bacterial invasion eosinophils: form small fraction of w. b. c. 2-4% of all w. b. c. life span is from 3-8 hours up to 8-12 days size: 12-15 um in diameter (same as neutrophil) nucleus: cytoplasm: bilobed dense chromatin.
