White blood cells engage in defence-related functions by consuming foreign objects and cell debris, eliminating pathogens and cancer cells, or by creating antibodies.
The immune system of the body includes white blood cells. They support the body's defences against illness and infection. Granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes are different types of white blood cells (T cells and B cells).
You run a higher risk of getting sick if your white blood cell count is low, especially if your neutrophil count is low. Additionally, your body is unable to defend itself if you contract an illness when your white blood cell count is low. In some situations, the infection might be fatal.
