The best place to start is by defining what white blood cells are. White bloods cells are otherwise known as leukocytes and they are part of the body's immune system.

These white blood cells are formed in the bone marrow and after this they circulate in the bloodstream and go to where the infections are. On average, an average adult will have around 4,000 to 10,000 white blood cells per microliter of blood. There are six different types of white blood cells.

They are as follows in order of most common to least common. Neutrophils, Eosinophils, Basophils, Bands, Monocytes, and Lymphocytes. An increase of white blood cells is an indication that there is an infection in the body.

The main function of white blood cells is to fight infectious diseases and anything foreign in the body. We can say that white blood cells are what keeps the body healthy.

white blood cells are the building blocks of our immune system.they help in the defence of body.

as soon as they recognize the entry of any foreign particle within the blood,they produce antibodies and kill the foreign particles before they cause any harm to the body.

white blood cells mainly destroy bacteria,viruses,toxins and other harmful substances.
