White blood cells are blood components that protect the body from agents that affect the body. White blood cells play an important role in the immune system by identifying, destroying and removing and spoiling cells, cancer cells and foreign matter from the body. Leukocytes are produced from bone marrow stem cells and circulate in the blood and lymph fluid.

Lipocytes are able to release blood vessels to move to the body’s vessel. Also, White cells are classified by the absence of granules or granules appearing in their cytoplasm (digestive enzymes or other chemical substances containing it) this cell is considered a granulocyte or Arron lite.

There are three types of granulocytes:

  1. Neutrophils.
  2. Eosinophils.
  3. Basophils.

By looking through a microscope these show granules in it.

  1. Neutrophils

These cells are single nuclei that are more than one long. Neutrophils play the most important role in blood circulation. They are chemically prepared for bacteria and are transmitted by tissue at the site of infection. These bacteria enter the body by spreading them into disease or dead cell etc. When neutrophile granules act as levos to digest the cellular macromolecules given. Neutrophils are also destroyed due to this.

The nucleus in these cells is also, double lobed and often appear in u size in blood smears.

2. Eosinophils

The nucleus in these cells is double lobed and often appear in u size in blood smears. Eosinophils are often found in connection with stomach and intestines. Eosinophils are phagocytic and mainly target antigen-antibody. These become complex when antibody is prevented from their diseases the substance is destroyed as their identity. Eosinophils become increasingly active during parasitic infections and allergic reactions.

3. Basophils

These are at least white blood cells they have multicellular nucleus and their necks contain substances such as histamine and heroin Haparin throws into the blood and prevents the formation of blood clots.

  • Histamine dilates blood vessels, increases capillarity of capillarity and increases blood flow which also helps to transmit leukocyte to affected areas. Basophils are responsible for the body’s allergic reaction.
  • Agronolytes

These are of two types are known as nonanoyl leukocytes. Lymphocytes and monocytes. These cells do not have clear ruptured granules. Agranulocytes is a large nucleus usually characterized by a lack of prominent cytoplasmic in granules.

  • Lymphocytes

After neutrophils, lymphocytes are the most common type of white blood cell. Also, These cells are spherical in shape with large nuclei and very small cytoplasm. There are three types of leaf cells, b cells and natural cells, t cells and b cells are important for specific immune responses, natural killer cells provide exceptional immunity.

  • Monocyte

These cells are the largest type of white blood cells. They may have different sizes. Nucleus often appears in renal size. Also, Monocytes move from blood to tissue and macrophages are present in large cells on all sides. Dendritic cells are usually found in tissue located in areas that come into contact with the external environment. Their skin, internally, nose, lungs and also, gas are found in the lower parts. Dendritic cells mainly work to present antigenic information to lymphocytes in ligaments and lymph organs.

White blood cell production:

These are produced inside the bone marrow bone. Some 0f these are mature in lymph nodes, thin, or Thomas gland. Blood cell production is often organized by body structures such as lymph nodes, spleen, liver, and kidneys. During an infection or injury, more blood cells are produced they are present in the blood. To measure the number of white blood cells in the blood is known as WBB or white blood cell count.

In blood test the number of these is 10,800-4,300 The reduction can be caused by a lack of disease, radiation exposure yahedi marrow. Also, An advanced WBB count can indicate the presence of a fatal or inflammatory disease, anemia, leukemia, stress, or tissue damage.

Types and function:

These cells (WBCS) are part of the immune system that help fight infection and protect the body against other foreign materials. To recognize the internal interference of various white blood cells, to kill the harmful bacteria and to protect the anti-bones and our body, also, bacteria and voice protect against future exposure.

Types:

There are many types of white blood cells:

  • Neutrophils

Neutrophils are about half of these cells neutrophils are usually the first cells in the immune system to respond to an invading bacteria or virus. As first responders, they are also sent to send signals to warn other cells in the immune system. These are the basic cells in the money. Once released from the bone marrow, these cells live for about 8 hours, but about 100 billion of these cells are produced from our body.

  • Eosinophils

They also play an important role in fighting bacteria. If there is an infection with insects, they play a very important role in response. However, they have allergy symptoms to play their role when they have an immune response to some of the growing things (such as vomiting). They account for only one percent of these cells in the blood of the cells, but there are high levels of digestive muscle.

  • Basophils

Basophils are about one percent of white blood cells. Also, These cells are probably known for asthma disease.

  • Lymphocytes (B and T)

These cells play a very important role in the immune system, Tt Cells responsible for directly killing many foreign invaders. These cells are responsible for mental immunity compared to other white blood cells. In contrast to the unspecified disturbance of cells, they produce antibodies that if any infection comes to our body, these cells are protective factors for it.

  • Monotitis

These are the trash of the immune system. It’s about 5% in the body. Their job is also, to clean up dead cells.

  • Formation

White blood cells begin in the bone marrow. Also, all blood cells, including white blood cells, red blood cells, and platelets.

Also, normal white blood cell count is usually between 4.000 and 10.000 cells/MCL.

In infection although the number of high white blood cells are many. The bone marrow can initially increase more than that, or can lead to a lack of white blood cells in the body. In infection, young white blood cells are exposed to blasts, often as quickly as possible in the body to get blood cells. White cell count has increased. Any form of pressure can also result from the release of white blood cells.

Infection:

  1. Cancers like leukemia, lymphasis, and myelomas in which more and more white blood cells are produced.
  2. Influenza such as inflammatory bowel disease and autoimmune disorders.
  3. Traversing trauma from fracture to emotional stress.
  4. Pregnant? The number of white cells in pregnancy is usually high.
  5. Also, Asthma and allergies. It increases blood cells known as eosinophils.
  6. Severe infection: bone marrow damage or disorders, also, including blood cancer or metastatic cancer, or loss of drugs or chemical related bone marrow.

Automatic diseases like lips:

  • Low white blood count symptoms:

knowing the function of white blood cells can be considered symptoms of low white blood count. White blood cells also, defend our body against infections. Some cells are part of our invincible immune system.

Fever, cough, pain or frequency of vomiting, also, blood pain in the stool or redness, swelling, or heat in the area of infection.

  • Chemotherapy:

one of the most common and dangerous side effects is that it affects white blood cells. Many functions in the body include white blood cells. These cells can also be sick themselves. One type of deficiency in all white blood cells can occur with immunodeficiency syndrome.

  • Leukocytes

After the treatment of these chemotherapy, John was told that his white cells were low and he should try to stay away from those who are ill for a few days. White blood cell disorders include a large number of disorders that affect white blood cells (WBB).

Which have 3 types of blood cells:

  • White blood cells are mainly involved in fighting diseases and participate in inflammatory responses.
  • Also, Red blood cells carry oxygen to the body.
  • Platelets help prevent blood.

The normal number of WBB limits is around 4 to 11 billion sales per liter.

Common types of white blood cell disorders:

  1. Leukocytosis:

leukocytosis is a large number of white blood cells the most common causes are medications such as infections, duodenum or leukemia.

2. Autoimmune neutropenia:

Autoimmune neutropenia occurs when the body produces antibodies that attack and destroy neutrophils.

3. Acute congenital neutropenia:

People with severe birth related neutropenia have frequent bacterial infections with conditions that have triggered a genetic change with severe neutropenia secondary.

4. Cyclic neutropenia:

It is also caused by neutropenia genetic changes, which cause severe congenital neutropenia like however neutropenia does not occur every day but is in cycles of about 21 days.

5. Leukemia:

Is a bone cancer that produces white blood cells in the bone marrow.

6. Granulomatous:

Disease is a disorder where multiple types of WBCS (neutrophils, mono, macrophagocytes) are unable to function properly, it is an inherited status and the results of multiple infections especially pneumonia and abscesses

7. Leukocyte:

Adhesion deficiency is a disorder where white blood cells cannot go to areas of infection.

Symptoms of white blood cell disorder

Symptoms of WBC disorders vary due to great importance. Some people with WBC disorders may have no symptoms.
