Neutrophils

In blood for 6-10 hours. They migrate out of circulation to infection site and phagocytose foreign material. (multi-lobed nucleus)

1

Eosinophils

Phagocytose antigen-antibody complexes. Also produce cytotoxic enzymes to damage larger particle. Numbers increase with allergic reactions. (bi-lobed nucleus)

2

Basophils

Immune response to parasites. Also accumulate at site of infection and release histamine/heparin as part of inflammatory response. (Bi-lobed nucleus)

3

Monocytes

Migrate to tissues to become macrophages that are phagocytic. Also antigen-presenting = inflammatory response (kidney-shaped nucleus)

4

Lymphocytes

B-cells develop into plasma cells which make antibodies (immunoglobulins). Helper-t-cells recognise antigens and activate cytotoxic T-cells to kill virally infected cells. (Big, deep staining nucleus)

5

Mast cells

Contain granules of heparin and histamine. Protect mucosal surfaces as are found in the mucosal tissues and not the blood.
