|
Neutrophils
|
From Myeloblasts
(Granular Leukocytes) 55-60% |
- 6 hour in circulation
- 1-4 days in connective tissue - Multilobed nucleus (3-4) - Very active in phagocytosis - Produces chemotactic stimuli for other cells to cross endothelium - 8-12 microns |
|
|
Basophil
|
From Myeloblasts
(Granular Leukocytes) 0-1% |
- A few hours to a few days
- Contain heparin (anticoagulant), histamin (dilation), SRS (dilation) - Related to mast cells - Associated with vascular disturbances, hypersensitivity reactions, and anaphylaxis. |
|
|
Eosinophil
|
From Myeloblasts
(Granular Leukocytes) 2-5% |
- 8 hours in circulation
- A few days in the CT - Bilobed Nucleus - Migrate into the CT - Antigen-Antibody complexes influence migration from the bloodstream. - Involved in parasitic infections, hypersensitive allergic reactions - 9-11 microns |
|
|
Monocyte
|
From Monoblast
(Agranular Leukocytes) 3-7% - CT: Macrophages - Liver: Kupfer Cells - Lung: Alveolar Marcophages - Bone: Osteoclast - CNS: Microglia - Epidermis: Langerhans Cell |
- 20 hours in the circulation
- Weeks to months outside (macrophages) - Effective phagocytes - Stimulates to divide, undergo further maturation outside circulation - Programmed to produce a variety of enzymes. |
|
|
Lymphocyte
|
From Lymphoblasts
(Agranular Leukocytes) 30-35% |
- Long-lived
- Cells that function in the Immune System - T-Cells: (Helper, Suppresor, Cytoxic, Memory) - B-Cells: (Develop into plasma that produce immunogloblins, Memory Cells - secondary immune response remembers invader) |
