Leukocyte, White Blood Cell

White blood cells are blood cells that play an important role in protecting the body from infections and other diseases. They can be of different types and shapes, but they all have a nucleus and amoeboid motility.

In a healthy body, there are three main types of white blood cells: granulocytes, lymphocytes and monocytes. Granulocytes are the most common type of white blood cell and can be divided into neutrophils, eosinophils and basophils. Lymphocytes, in turn, are the main immunocompetent cells and can be classified into T lymphocytes (T cells) and B lymphocytes (B cells). Monocytes are also an important type of white blood cell because they are able to capture and digest foreign substances.

When you are sick, other types of white blood cells may be found in your blood, including immature forms, which may indicate infection or other health problems. For example, with viral infections the level of lymphocytes may increase, and with bacterial infections - granulocytes.

White blood cells play an important role in the immune system, helping the body fight infections and other diseases. They are also involved in the regulation of inflammation and other processes associated with the body's response to foreign agents.

In addition, white blood cells can be used as markers in the diagnosis of various diseases and conditions. For example, the level of white blood cells in the blood can change due to various infections, autoimmune diseases, cancer and other conditions.

Thus, white blood cells are important components of the immune system and play a key role in protecting the body from various threats. Understanding their functions and changes in various conditions helps doctors and clinicians better understand the causes and symptoms of diseases and develop more effective treatments.



Leukocytes are nucleated blood cells that play an important role in protecting the body from infections and other diseases. They have amoeboid motility and can travel through blood vessels to reach sites of inflammation or infection.

In a healthy human body, there are three main types of white blood cells: granulocytes, lymphocytes and monocytes. Granulocytes are cells that contain granules with various chemicals such as histamine, serotonin and others. Lymphocytes are the main type of immunocompetent cells that are responsible for the production of antibodies to various infections and foreign substances. Monocytes are larger cells that can migrate into tissues and participate in inflammatory processes.

In diseases, the number of different types of white blood cells may increase in the blood. For example, during infections and inflammatory processes the number of granulocytes and lymphocytes increases, and in autoimmune diseases - monocytes. Immature forms of white blood cells can also appear in various diseases such as leukemia and lymphoma.

In addition, leukocytes are involved in regulating the body's immune response. They interact with other cells of the immune system, such as T lymphocytes and B lymphocytes, and help them produce antibodies to various antigens. Leukocytes can also destroy foreign cells and protect the body from infections.

Thus, white blood cells are important blood cells that are involved in protecting the body and regulating the immune response. Their number and shape can change in different diseases and conditions, allowing doctors to diagnose and treat various diseases.



Leukocytes and the leukocyte profile of a healthy person Leukocytes are an important part of the body's immune system. Therefore, any deviations in the blood formula serve as a reflection of the state of immunity, i.e. the body's defense system associated with the formation of antibodies to protect all its components from attack by surrounding viruses, bacteria and other foreign agents.

As the body heals or changes occur in the immune system, white blood cells also respond. Normal values ​​vary for different types of white blood cells. Typically, the total white blood cell count ranges from 4 to 5.5 per liter. These numbers are based primarily on normal blood counts for women of reproductive age. In men, results may be slightly better due to higher testosterone levels, which sometimes boost white blood cell counts. For children and pregnant women, these indicators vary widely. Thus, in newborns or premature infants, as well as during



Leukocytes, cells or white blood cells, make up two-thirds of the total number of human blood cells. These cells help protect the human body from harmful substances, viruses and other foreign bodies. Leukocytes are also known as white blood cells, or WBC (white blood count). Blood cells constantly circulate throughout the body, and the blood itself flows through small holes and channels called capillaries, through which nutrients move between the circulatory system and tissues
