What are white blood cells and what is their function in the human body?

White blood cells are almost 900 times less than the red blood cells, there are several types of it, whose primary task is to fight infection.
Small red cells are much more numerous in the blood and give it its color. But white blood cells also play an important role. White blood cells are also called leukocytes.
The most numerous white blood cells are granulocytes.
These cells go in and out in the blood at the point where germs are collected or where is injured tissue. Some of them, which we call Neutrophils, take the bacteria within and destroy them. Leukocytes produce substances that soften and digest dead tissue and produce pus.
Other white blood cells are called lymphocytes.
Their number is often increased when the body for a longer time is exposed to an infection. They are an integral part of the mechanized body, and as we can see, their role is very important.
The third type of white blood cells are Monocytes.
These cells, together with other cells in tissues, have the ability to accept parts of dead matter.  They can also surround some substance such as dust, and prevent it to come into contact with healthy tissue cells.
Although the white blood cells are needed by the body, it is not so good when there are too many.
