White blood cells
White blood cells are one of the main blood cells in addition to platelets and red blood cells, which is one of the main lines of immunity in the human body. White blood cells are about 4,401,000 cells in one microliter of blood, Blood in healthy adults; these cells are produced in a stem cell located in the bone marrow, and in this article we will introduce you to the function of white blood cells.
Function of white blood cells
- Protecting the body, defending it against the attacks of various microbes, by devouring it, and analyzing it. This function may lead to the death of some white balls, leading to the formation of so-called urethral cells.
- Acid cells or azinovil cells produce a substance called histamine that causes blood vessels to expand, and increases the sensitivity of the body, in addition to playing a minor role in the process of thrombosis.
- The basophil cells or cells of the pesophyll present a substance called heparin, which works to prevent blood clotting.
- The lymphocytes produce antibodies equivalent to microbes, or the deposition of these toxins.
- Monocyte cells help to heal tissues by devouring bacteria, single-celled parasites such as amoeba, and others.
White blood cells
- Favorite categories: They are enzymes associated with the membrane, which are characterized by the presence of granules in the Hyali, and these molecules are in the red bone marrow, and these molecules to digest the particles ingested, and there are three types of them: acid cells, and basic, and neutral.
- Favorite categories: These pellets are characterized by the absence of granules in the Hyali. They contain non-specific granules resembling the particulate matter. These pellets consist of lymph nodes, liver, and spleen, and there are three types: monocytes, plaques, and lymphocytes.
Life span of white blood cells
White blood cells are short-lived cells compared to other blood cells. They live for a few hours in lymphocytes and one to two days in other white cells.
Change in the number of white blood cells
- Increase in number: The number of pregnant women, children, and patients with acute pneumonia.
- Decrease in number: The number of people suffering from starvation and malnutrition is lower in people suffering from red blood cell damage and from chronic diseases such as typhoid fever.
