Leukocytes: definition and function
So, leukocytes. These are white (or rather, transparent) blood cells or cells. They are of different types and sizes, but they are united by one common function, namely, the protection of our body from infections. The main types of white blood cells are neutrophils, eosinophils, monocytes and lymphocytes.
Some white blood cells are able to absorb, actually swallow and digest microorganisms and other foreign bodies. They easily penetrate into any foci of infection. With a large number of foreign bodies, these heroic leukocytes (or phagocytes, as they are also called) swell to an enormous size and collapse. They are replaced by new ones, in even greater numbers.The well-known pus is just the graveyard of dead leukocytes.
Other white blood cells can produce antibodies that can destroy foreign protein molecules that have entered the body.
