What Is Phagocytes ?

Phagocytes are that part of the white blood cells which is related to the important process of phagocytosis. White blood cells or leucocytes, with all its members, are solely responsible for providing immunity to the body of the human beings.

What Is Phagocytes

Thus, phagocytes are no exception. Its main role is to clear away the dead cells from the body in a systematic manner that is without causing any harm to the body in the process.

There are about 6 billion phagocytes in the human body. These members are not found particularly in any organ but flow around all the parts through bloodstream. There are two types of phagocytes based on whether they help in the process of phagocytosis or not. These two types are professional and non-professional phagocytes. The professional phagocytes are consisted of neutrophils, macrophages, monocytes, mast cells and dendritic cells. The fact that only professional ones assist in phagocytosis is because only they are provided with a molecule name receptors which help in detection of harm causing and usually foreign objects in the body.

Function Of Mononuclear Phagocytes

Function Of Mononuclear Phagocytes

Mononuclear phagocytes form an integral part of leukemia or the white blood cells of the human body which deals with providing immunity to the body. To find out the cure of a particular disease or to improve the already existing methods, it is important to understand the functions and working mechanisms of the human immunity system and its various members.

In this article however, we will just stick to the functions of mononuclear phagocytes.

Mononuclear phagocytes or the monocytes and the phagocytes perform the essential function of phagocytosis and helping in killing of the various microorganisms harmful for the body. Now let us first understand what monocytes and phagocytes are. Monocytes are that part of the immune system which helps in replenishing dendritic cells and macrophages in normal conditions and in tackling inflammation of any kind. Phagocytes are those members of the immunity system which help the body by devouring all the toxic foreign particles and also the dead cells apart from the bacteria. This process of devouring the toxic substances by phagocytes is called phagocytosis.More...

 

Role Of Phagocytes

Role Of Phagocytes

Phagocytes are the type of leucocytes or white blood cells which destroying and ingesting of harm causing bacteria and dead cells. This act is called phagocytosis which is the main contribution of phagocytes in human immunity. There are two types of cells responsible for this process of phagocytosis. They are neutrophils and macrophages.

The phagocytes use a very highly concentrated enzyme contained in them during the process of phagocytosis. Phagocytes also help during a process called apoptosis which can be said as a planned cell death. In a human body, the cells are dying all the time. Also new cells are forming in their place. However, a balance is necessary to maintain between the two. The role of phagocytes comes to play when the need for the body to free itself of the millions of dead cells arises. It is important to mention here that the phagocytes of not only human body, but bodies of other jawed vertebrates can be divided into two types -- the professional and the non-professional phagocytes based on their participation in the process of phagocytosis. It is the professional ones which carry out this task in an orderly fashion, without causing any sort of inflammation in the body.More...
