Otherwise, the bilirubin is excreted into the bowel and ends up in the feces. Moving along to WBC, unlike RBC, they have nuclei, but have NO Hb. The ratio of RBC to WBC is approximately 700 to 1. Granular WBC come from red bone marrow and contain cytoplasmic granules. They have lobed nuclei and include neutrophils , eosinophils and basophils.
Neutrophils have the greatest activity following bacterially destroyed tissue.
