TYPES OF WHITE BLOOD CELLS --
The three major types of white blood cells are:
- Granulocytes
- Monocytes
- Lymphocytes
There are three different forms of granulocytes:
- Neutrophils
- Eosinophils
- Basophils
Monocytes can develop into two types of cell:
- Dendritic cells are antigen-presenting cells which are able to mark out cells that are antigens (foreign bodies) that need to be destroyed by lymphocytes.
- Macrophages are phagocyte cells which are larger and live longer than neutrophils. Macrophages are also able to act as antigen-presenting cells.
Lymphocytes are cells which help to regulate the body's immune system.
The main types of lymphocytes are:
- B lymphocytes (B cells)
- T lymphocytes (T cells)
Granulocytes are phagocytes, that is they are able to ingest foreign cells such as bacteria, viruses and other parasites.
Granulocytes are so called because these cells have granules of enzymes which help to digest the invading microbes. Granulocytes account for about 60% of our white blood cells.
Neutrophils are by far the most prevalent of these cells. Each neutrophil cell can ingest up to between around 5 and 20 bacteria in its lifetime.
Eosinophils are involved in allergic reactions and can attack multicellular parasites such as worms.
Basophils are also involved in allergic reactions and are able to release histamine, which helps to trigger inflammation, and heparin, which prevents blood from clotting.
