HISTOLOGY OF THE IMMUNE ORGANS Cells at Work Cells at Work Image Cell Type Function First responders to inflammation, engulf and destroy Polymorphonuclear Neutrophils (7) bacteria Polymorphonuclear Eosinophils (10) Fight parasitic infections, regulate allergic reactions Polymorphonuclear Basophils (12) Release histamine and other inflammatory substances Develop into macrophages, engulf and destroy debris and Monocytes (15) pathogens B-cells Produce antibodies to fight infections T-cells Coordinate immune response, directly attack infected cells Natural Killer Cells (NK cells) Destroy virus-infected and tumor cells NORMAL BLOOD CELL COUNTS Cell Type Mean Number per (mm³) Normal Range White Blood Cells (Leukocytes) 7400 4500-11,000/mm³ Neutrophils 4400 40-60% Eosinophils 200 1-4% Basophils 40
