- Leucocytes (white blood cells)
- Lymphocytes
- T lymphocytes
- Some become T-killer cells. These just kill any cell that shows signs of infection. They kill using a chemical like hydrogen peroxide.
- Some become T-helper cells. These secrete cytokines which stimulate B lymphocytes to produce memory cells.
- B lymphocytes
- These undergo clonal selection and expansion. This is when the lymphocyte with the right antibody on it is chosen to fight the pathogen and multiplied via mitosis.
- Some then are converted into plasma cells which produce antibodies,
- These undergo clonal selection and expansion. This is when the lymphocyte with the right antibody on it is chosen to fight the pathogen and multiplied via mitosis.
- T lymphocytes
- Phagocytes
- Neutrophills
- These are the most common types of white blood cells. They engluf any pathogen that they come accross via phagocytosis.
- Macrophages
- These engulf a pathogen and incorporate its' antigen onto its cell surface membrane. This is then used to recognise the antigen causing other lymphocytes or neutrophills to get rid of it.
