White blood cells
White blood cells or white blood cells are one of the main and primary blood cells in the body, in addition to red blood cells and platelets. Cells or white blood cells are an important part of the immune system as cells of the immune system. The primary function of white blood cells or cells is Defend the body against infectious diseases and immune system stimuli, although different forms of white blood cells are all made up and formed from a multi-cell stem cell in bone marrow known as the hematopoietic stem cell.
White blood cells are called this name because, after excitation, ie, centrifugation of a sample of blood, the white blood cell form is a thin white layer of cells that are innate between the red blood cell and red blood cells.
Types of white blood cells
White blood cells are divided into two main types, depending on where they are located:
- These white blood cells include lymphocytes, plaques and nuclei. These white blood cells are formed in lymphatic tissues such as lymph nodes, spleen and lymphatic tissues.
- These granules are enzymes linked to the membrane and work to digest the ingested particles. The granular white blood cells are divided into three types: a basal cell, an inert cell and an acidic cell, called by color. These cells are formed in the red bone marrow.
The number of white blood cells in a natural person
The lack or increase in the number of white blood cells often leads to a disease. The number of normal blood cells in a microliter of blood is about 4000-11000, which is about 1 percent of the healthy adult without disease. When the body is attacked by antigens, White blood cells and leukemia or leukemia are higher than normal and reduce the number of white blood cells and fall below normal in many cases.
The white blood cells live only a few hours in lymphocytes and from one to two days in the rest of the white cells. This rate is very short with other blood cells and the white blood cells leave the circulatory system to function in the tissues.
