The most common type of white blood cell is called neutrophils. The function of this type of white blood cell is to ingest and kill organisms that are causing an infection.
A second kind of white blood cell is the eosinophils. Its role is to reduce the intensity of allergic reactions as well as to fight against parasitic worms.
Neutrophils fight against fungal and bacterial infections.
Eosinophils primarily fight against parasitic infections.The main causes of E are allergies such as asthma, hay fever, and hives.
Basophils are responsible for allergic response by releasing the chemical histamine and causing inflammation.
Lymphocytes are the coordinators of the immune system, helping it to fight against intracellular bacteria and tumour cells.
Monocytes make immune cells to kill the pathogens and they remove dead microorganisms.
