White blood cells function:
White blood cells function are listed below in this case.White blood cells are a vital component of the blood.
They are important for fighting infections (infections), and are essential for a healthy body.
A high white blood cell count may indicate that the immune system is working to eliminate an infection, and it may also be a sign of physical or emotional stress.
In addition, people with certain types of leukemia have a high white blood cell count.
As for their low numbers, this indicates the presence of harm or some situation that destroys cells at a faster rate than their rate of formation, or that the body produces fewer cells.
White blood cells make up about 1% of blood cells and are essential for regulating the function of the immune system.
White blood cells are continually produced by the bone marrow and stored in the blood and lymphatic system to help protect the body from any infection or disease.
Types of white blood cells:
White blood cells are the components responsible for protecting the body from disease and foreign bodies.
Generally speaking, most people produce about 100 billion leukocytes per day, as there are normally 4000-11 thousand leukocytes in every microliter of blood in a healthy person, but the number may vary depending on race.
Leukocyte patterns and functions:
- Lymphocytes (lymphocytes): They are an essential component in the production of antibodies that help the body fight germs, viruses and other threatening agents.
- Neutrophils (neutrophils): essential for resistance to germs and fungi.
- Basophils: These cells alert the body to the presence of an infection by secreting chemicals into the bloodstream, especially in cases of allergies.
- Eosinophils: These corpuscles are responsible for destroying parasites and cancer cells, as well as being part of the allergic response.
- Monocytes: These cells are responsible for attacking and destroying germs that enter the body. They can move to other organs (such as the spleen, liver, lungs, or bone marrow) when needed, where they turn into cells called phagocytes (phagocytes).
Phagocytes have many functions, such as removing dead or damaged tissue, destroying cancer cells, and regulating the immune response.
Causes of high white blood cells:
An elevated white blood cell count is known as leukopenia, and it occurs in response to one of the following conditions:
- Infection (such as whooping cough or tuberculosis).
- Treatment with some medications, such as corticosteroids.
- Immune disorders or a bone marrow disorder.
- Some types of cancer, such as acute or chronic lymphocytic leukemia.
- Emotional distress.
- Allergic reactions.
- Extreme exercises.
All white blood cells are affected in some cases, but elevated levels of a specific type of leukocyte may indicate a specific medical condition:
- Mononucleosis: High levels of mononucleosis may indicate a chronic infection, autoimmune defect, blood disorder, cancer, or other medical conditions.
- Lymphocytes: A condition of high lymphocytes is called lymphocytic leukemia, which may occur as a result of a virus infection or an infection such as tuberculosis, in addition to that it may be associated with certain types of lymphomas or some cases of leukemia.
- Neutrophils: The high level of neutrophils in the body leads to a condition known as neutrophilic leukocytosis. This condition is considered a normal immune response to an accident, such as an infection, injury, inflammation, certain medications, or certain types of leukemia.
- Basophils: Levels of basophils are elevated in those with a history of hypothyroidism, or as a result of some other medical condition.
- Eosinophils: A high eosinophil count indicates an immune response to a parasitic infection, allergen, or asthma.
The white blood cell count may rise suddenly for an unspecified cause, so-called idiopathic eosinophilia syndrome, which can lead to serious complications, such as damage to the heart, lung, liver, skin, or nervous system.
People with this syndrome may have the following symptoms:
- Weight loss.
- Night sweats.
- pain in chest.
- Flatulence (swelling).
- Abdominal pain.
- Weak and asthenic.
Other forms of imbalance:
If the levels of white blood cells are lower than normal, this could be a sign of a person’s immunity decreased.
This may be caused by HIV or immunosuppressive drugs.
A lack of white blood cells is the reason why people who use drugs or have diseases that suppress the immune system face an increased risk of infection.
The production of abnormal blood cells is also a feature of some types of cancer, such as leukemia and lymphomas, which are conditions that may occur in the bone marrow and are commonly known as myeloproliferative disorders.
These conditions develop when too many immature blood cells are produced, resulting in an imbalance. These disorders are rare but may progress to malignancy.
Symptoms and diagnosis:
The actual effect of leukocytosis depends on the condition or the causative agent. A change in the white blood cell count may not cause any symptoms. But if symptoms do appear, the doctor uses a blood test to assess the counts, and then other tests are done necessary to determine the exact cause of the problem.
Does leukocytosis always indicate an infection?
Not necessarily (though it is the most common cause), but other conditions lead to an elevated level of white blood cells, such as stress, and some medications, especially steroids, in addition to some types of cancer such as leukemia.
A doctor should evaluate any white blood cell count above the normal limit.
