Lymphocytes are the cells of the immune system, which are a subspecies of leukocytes agranulocytes groups, ie white blood cells. These cells are considered the most important cells of the immune system, which provide the production of antibodies, i.e. humoral immunity, contact with other cells, i.e. cell-mediated immunity, and regulate activity of other blood contains, on average twenty to thirty-five percent of lymphocytes.However, the human blood contains only two percent of lymphocytes, and all remaining ninety-eight percent are in body tissues.If the number of lymphocytes in the body increases, such a phenomenon is called lymphocytosis.If this number is decreasing, this process is known as lymphopenia.The lymphocytes, in turn, are formed in the tonsils, spleen, lymph nodes, Peyer's patches, thymus, appendix, and bone marrow.Most human body cells secrete small, which are small cells having dark nucleus.In general, according to the morphological characteristics, including lymphocyt

es secrete two types.The first type is a large granular lymphocytes, which are rapidly dividing cells of the lymphoid series.Besides isolated and small lymphocytes.

Variety and function of lymphocytes

During pregnancy, fetal cells are produced by the liver cells, bone marrow and stem cells.The adult body is saturated only lymphocytes from bone marrow.

These cells are the most important cells of immunity which can simultaneously produce antibodies to pathogenic cells and destroy them.

Among lymphocytes isolated B-lymphocytes, T-lymphocytes and NK-cells.

With already produced antibodies in B cells detect foreign microbes and single cells.T-lymphocytes, in turn, control the immune system response.In the case of strengthening of the response to the fight include T-helper cells.But during the suppression of the response function of T-suppressors.These in turn reduce the increased B-lymphocyte response.There are also NK-lymphocytes.They are researchers tissue cells that destroy mutated cells, such as cancer.Recent cells are considered the largest and lymphocytes T and B are considered to be the smallest.

What is the rate of lymphocytes in the blood

adult blood at full health numbers from one thousand to three thousand lymphocytes in one microliter.In this case T-cells are from sixty to eighty percent of the number of all white blood cells, B-lymphocytes are from two to twenty percent and NK-cells are from five to twenty percent.

blood lymphocytes in children

blood lymphocytes in children is not constant, since with increasing age and their number varies.However, from day birth to four days and the number of lymphocytes takes from twenty-two to twenty-five percent of all white blood cells.From the fourth to the seventh day is the amount varies from forty to forty-two percent.Since the eighth day from the day of birth and continuing for up to six years, lymphocytes rise from forty-five to sixty-five percent.And now six years old platelet level is gradually reduced to eighteen years and he is set to an amount of twenty-five to forty percent.

all diseases, unfortunately, it is simply impossible to protect their children.But parents need to know how the disease and there are children that they are for a carry.That is why, dear parents, please pay special attention to the number of lymphocytes in your child's blood test.

known as lymphocytes are the blood cells that are responsible directly for the state of the child's immunity, consequently, for his health.Lymphocytes are the first to come to the fight against infectious diseases and viruses recognize different bacteria.In addition, they are actively fighting the disease-causing bacteria.

But because of the sharp decline in immunity or because of the presence of any disease level of lymphocytes in the blood can be increased.In order to determine if your child has any disease, consult a doctor and get tested.

If elevated levels of lymphocytes in the blood is detected in a child, it may indicate the presence of enough diseases.One of these infections can be measles, whooping cough, malaria, chicken pox, hepatitis and herpes.Children who suffer from anemia, leukemia or asthma can also increase the level of lymphocytes in the blood.

In any case, if the child's blood analysis showed increased lymphocytes, please consult your doctor to determine the cause and proper treatment is appointed.

As has become known, elevated levels of lymphocytes called lymphocytosis in the blood, which in turn can be of two types, namely absolute or relative.

absolute lymphocytosis often leads to the above-mentioned infectious diseases, but the relative lymphocytosis causes influenza, purulent-inflammatory diseases, viral infections, and other diseases that occur due to lowered immunity.

The worst consequence is the emergence of lymphocytosis in such diseases as leukemia.This disease manifests itself because of insufficient rapid maturation of lymphocytes.But do not immediately panic, as this disease is observed only in very debilitated children.It also appears later many disorders in the body, which are installed with the help of medical research.

Of course, for every parent is very important to know how obereganiya Child from various diseases.It should therefore monitor the diet of the child, to temper it, to carry out preventive measures, vaccinations and engage in physical exercise.And even if you still think that your child is ill, it is best to consult a doctor and not self-medicate.
