The role of white blood cells, the range of normal values, classification and the reasons for the low.

White blood cells are the "guardians" of the human body's struggle against disease.
when the bacteria invade the human body, white blood cells can pass through the walls of capillaries through deformation, concentrated to the site of the bacterial invasion, the bacteria surrounded, swallowed.
if the number of white blood cells in the body is higher than normal, it is likely that the body has inflammation.
in general in our human body white blood cell content should be 4 x 10 x 9 to 11 x 10 x 9 / liter of blood, so as to play the most comprehensive defense.
many people in ordinary life often unprovoked appearance of dizziness, fatigue, soft limbs, loss of appetite, low fever and so on, in addition to some people also often appear insomnia and other symptoms, these are common symptoms of white blood cell reduction.
the following small compilation to introduce for you the role of white blood cells, white blood cell normal value range, white blood cell classification, the reasons for low white blood cells, the cause of high white blood cells, white blood cells low what to eat? The difference between symptoms of white blood cell reduction, white blood cell and red blood cell.
take a look! The number of white blood cells in adults is 5000 to 9000 units per cubic millimeter, of which neutrophils account for 0.50 to 0.70, eosinophils account for 0.005 to 0.05, alkaline granulocytes account for 0.005 to 0.01, single-core cells account for 0.03 to 0.08, and lymphocytes account for 0.20 to 0.40.
children have more white blood cells in their blood than adults.
different physiological states, such as pregnancy, can cause changes in the number of white blood cells. When there is
inflammation, the number of white blood cells in the blood increases significantly.
the protective protection of various types of white blood cells varies.
1, phagocytosis is the oldest organism, but also one of the most basic defense mechanisms.
has no specificity for the object to be eliminated, which is called nonspecific immune action in immunology.
the phagocytosis of neutrophils and mononucleosome cells is very strong, and eosinophils have a strong mobility, but their ability to gobble is weak.
2, specific immune function lymphocytes, also known as immune cells, play a major role in the body-specific immune process.
so-called specific immunity, is lymphocytes against a specific antigen, the production of corresponding antibodies or local cell reactions to kill specific antigens.
the stemhocy cells in the blood are divided into T lymphocytes and B lymphocytes according to their occurrence and function differences.
3, the function of alkaline and eosinophils, the two cells in the blood do not stay for a long time, mainly in the tissues. the number of blood cells in normal people in the normal range of
white blood cells is 4000-10000 / s.L (microliters), of which neutrophils account for 0.50 to 0.70, eophilic granulocytes account for 0.005 to 0.05, osteophilies account for 0.005 to 0.01, single-core cells account for 0.03 to 0.08, and lymphocytes account for 0.20-0.00.00%.
1, Gram-negative Bacillus infections, such as typhoid fever, paratyphoid salmonella, viral infections, such as influenza, viral hepatitis, parasitic infections, such as malaria.
2, want to get more information on related diseases, can search the application market "sunshine health school", download and install, at any time to obtain more disease science knowledge of certain blood diseases, such as regenerative anemia, granulocyte deficiency, white blood cell not increased leukemia and so on.
3, autoimmune diseases, such as systemic lupus erythematosus, immune antibodies caused by the reduction of white blood cells.
4, physical and chemical injury and drug reactions, such as benzene and its derivatives caused by radiation damage, chemical poisoning, such as chloramphenicol, baotaipine, anti-cancer drugs and other reactions.
5, other, such as cirrhosis of the liver, spleen function, etc.
treatment recommends treatment, but also can take Traditional Chinese medicine conditioning.
classification 1 of white blood cells, macrophages are developed by the differentiation of mononucleocytes, mononucleic cells are present in almost all tissues.
macrophages to devour and digest cell residues and pathogens, a process known as phagocytosis.
lysozyme stoyne stoyne stoyase in macrophages releases lysozymes to destroy pathogens.
phagocytosis cells or full-time antigen-presentation cells that participate in adaptive immunity. in addition to immune function,
, phagocytosis also acts as a promoter of reproductive cell development, sex hormones, reabsorption of bone tissue, and blood formation.
2, dendritic cells are similar to phagocytosis cells, and dendritic cells are also mononucleocells.
dendritic cells mature, they protrude from many dendrites or pseudo-foot-like protrusions, similar to the dendrites of neurons.
dendritic cells are usually found in areas of the skin (mucous membrane) that come into contact with the outside world, such as the skin, inner nose, lungs, stomach and intestines.
dendritic cells help the body identify pathogens and initiate a specific immune response by ingesting, processing, and transmitting antigens to lymph nodes and lymphatic cells.
3, B lymphocyte B cells are one of the components of lymphocytes.
B cells are stimulated by antigens, they synthesize and secrete a special protein, antibodies, that bind to antigens to help the body identify pathogens and make them target cells removed by other immune cells.
B cells, known as memory cells, can maintain memory of pathogenic biomolecular markers, protecting the same antigen from infection when it re-enters the body.
this allows the body to maintain long-term immunity to specific pathogens.
4, T lymphocytes are similar to B cells, and T cells are also among the lymphocytes.
T lymphocytes come from the bone marrow and migrate to the thymus to differentiate and mature.
T cells participate in the immune response by directly killing target cells and releasing lymphocytes.
T cells include cytotoxic T cells, auxiliary T cells, inhibitory T cells, natural killer T cells, and memory T cells.
cytotoxic T cells directly kill target cells, and auxiliary T cells assist B cells in producing antibodies that inhibit B cells and other T cells against the progenitor's immune response.
NKT cells have both T-cell and NK cell properties, nkT cells are not NK cells but T cells.
5, natural killer cells are lymphocytes distributed in the blood circulation, which can identify infected cells and senescent cells.
NK cells contain chemical particles, NK cells are able to identify tumors or infected cells, by releasing chemical particles to devour and destroy the diseased cells.
these chemical particles dissolve the cell membranes of diseased cells, causing apoptosis and eventually killing the target cells.
should also distinguish between NK cells and certain T cells, such as NKT cells, without confusion.
6, neutrophils neutrophils are neutrophils, which have granules, have a phagocytosis, and release chemical particles during the phagocytosis process to destroy pathogens.
the nucleus is leafy.
neutrophils are the largest number of granulocytes in the blood circulation, and the body can quickly appear in the area of infection and damage when the body is invaded by pathogens.
7, eosinophils eosinophils are white blood cells with phagocytosis, when allergic reactions and parasitic infections, eophilic granulocytes will increase significantly.
eosinophils have large, eosinophilic particles that release chemicals to eliminate pathogens.
eosinophils often exist in connective tissue in the gastrointestinal tract, the nucleus is double-leafed, and the blood smears are often U-shaped distribution.
8, alkaline otophilic granulocytes are granulocytes containing histamines and heparin and other substances in the particles (with granulocytes), heparin can dilute the blood, inhibit the formation of blood clots, histamines can dilate capillaries, increase blood flow, which helps white blood cells flow to the infected site, the body's allergic reaction is mainly related to these substances.
alkaline granulocytes are the fewest white blood cells, and the nucleus is leafy.
the causes of low white blood cells1, physical factors: such as X-rays, gamma rays and so on.
2, infection factors: (1) bacterial infections such as typhoid fever, paratyphoid fever, brucellosis, Shigella dysentery, granule tuberculosis, sepsis and so on.
(2) virus infections such as yellow fever, viral hepatitis, infectious mononucleosis, measles, chickenpox, rubella, dengue fever, epidemic haemorrhagic fever, infectious atypical pneumonia, human avian influenza, etc.
(3) Lik sub-body infection epidemic typhus typhoid fever, disease-related disease, recurrent typhus tydtyp, riker skinpox.
(4) the protozoa is infected with malaria, toxoplasmosis, black fever.
(5) helical infection regressive fever.
(6) mycoplasma infection mycoplasma pneumonia, etc.
3, drug factors: such as certain anti-tumor drugs, anti-thermal analgesics, anti-thyroid drugs, sulfonamides, antibiotics, pyrethroids, antimalarial drugs, anti-diabetic drugs, anti-tuberculosis drugs, anti-epileptic drugs, antihypertensivedrugs, H-blockers, diuretics, etc. ( see drug instructions).
4, chemicals: including benzene and its derivatives.
5, disease factors: such as hematopoietic diseases, including leukemia, malignant tissue cell disease, regenerative anemia, bone marrow fibrosis, burst sleep hemoglobinuria, giant cell anemia, etc. ;
6, genetic factors such as infant hereditary granulocyte deficiency, for autosomal recessive genetics.
the reason for the high white blood cells of normal adults the number of white blood is 4.0 x 10 of the nine square to 10 x 10 square snr.
the reasons for the high white blood cells, divided into pathological white blood cells increased and physiological white blood cells increased.
. 1, pathological white blood cell increase 1, some bacterial infectioncause of diseases, especially purulent cocci caused by local inflammation and systemic infections, such as: abscess, pus meningitis, pneumonia, appendicitis, otitis media, tonsillitis, pus, pytokinel, pylixitis, fallopian tubeitis, gallbladderitis and septicaemia.
2, some viral infections caused by diseases: encephalitis B, infectious mononucleosis, measles and so on.
3, severe tissue damage or necrosis: such as after major surgery, burns, acute bleeding severe trauma, vascular embolism, etc.
4, allergic reactions: such as blood transfusion reactions, drug allergies, acute abnormal reaction diseases, etc.
5, poisoning reaction: such as various drug poisoning, pesticide poisoning, heavy metal poisoning, diabetic acidosis, pregnancy poisoning and so on.
6, tumors and blood diseases: chronic granulocytic leukemia, acute granulocytic leukemia, etc.
7, the application of certain chemicals of white blood cells to promote the increase of white blood cells, more commonly seen during chemotherapy and radiotherapy treatment due to a sharp decline in the number of white blood cells, the need to raise white blood cells as soon as possible and the next course of treatment patients.
, physiological white blood cells increase physiological white blood cell increase more common in newborns, menstruation, childbirth, mood changes and injection of epinephrine and so on. What do
white blood cells eat low? 1, mushrooms: because mushrooms contain polysaccharides, it contains high unsaturated fatty acids, but also contains a large number of vitamin D can be converted to the marsotosterol and sterols, leukocyte reduction has a clear effect, mainly in improving the immune capacity of patients.
the average family can use fresh mushrooms to cook or cook regular food.
2, red dates: It is generally known that the red herring is tonic blood, on platelets and white blood cells have a certain impact, can moisturize the blood, and can improve the symptoms caused by the reduction of white blood cells caused by weakening immunity.
3, high vitamin diet: such as yeast hair noodles, cereals, peanuts, green fresh vegetables, especially a citrus fruit as a good, to supplement vitamin C, B and folic acid, this is due to the vitamin to enhance the body's immunity, can increase the number of phage cells, strengthen the vitality of natural killer cells, promote white blood cell production and participate in the recovery of cells destroyed free radicals, can alleviate the symptoms of white blood cell reduction.
4, party participation: its main role in gas supplementation, spleen and stomach and gas-fed blood.
party ginseng contains a variety of sugars, phenols, sterols, volatile oils, jaundice glucose, saponin and trace alkaloids, with enhanced immunity, dilated blood vessels, bucking, improving microcirculation, enhance blood-forming function, can make the proportion of neutral white blood cells increased.
5, ox myelin: ox myelin can replenish the kidneys.
leukocyte reduction is mostly a Chinese medicine blood loss, the disease of inflator, related to the loss of bone marrow, therefore, for leukocyte reduction patients, the use of bovine myelin is to have a certain effect, can receive the effect of tonic work, beneficial blood.
6, compound a gum: mainly play the role of gas-fed blood, compound a gum can prevent, fight, reduce the damage of cytotoxin to the bone marrow hematopoietic system, protect the normal division and growth of hematopoietic stem cells, white blood cells significantly increased.
symptoms of white blood cell reduction1, infectious granulocyte reduction: common in viral infectious diseases, such as viral hepatitis, measles, influenza, infectious mononucleosis, etc.;
2, drug-induced granulocyte reduction: chloramphenicol, helimycin, sulfonamide, compound aspirin caused by granulocytic cell reduction reports are often seen.
3, radiation linear granulocytes: engaged in radiation work or exposure to radioactive substances, can lead to the reduction of white blood cells.
4, acquired immune granulocytes: connective tissue disease and chronic active hepatitis, etc. can be found anti-white blood cell antibodies in the serum.
5, myelocytic reduction of myeloid disease: lymphoma, multiple myeloma, myeloma cancer and other patients can have granulocyte sylocutane reduction.
the difference between white blood cells and red blood cells white blood cells colorless spherical, has the nucleus, the volume is larger than red blood cells, diameter between 7 to 20 m.
normal human white blood cell count is in the range of 4000 to 10000/mm3, with an average of 7000/mm3.
red blood cells are small in size, with a diameter of only 7 to 8 m, shaped like a disc, with a deep erthred in the middle and a thick edge.
it is elastic and malleable, changing shape when passing through a capillary that is smaller in diameter, and still restored to its original shape.
normally mature red blood cells have no nuclei and no organelles such as Gorky complexes and mitochondria, but they still have metabolic function.
red blood cells are rich in hemoglobin, hemoglobin accounts for about 32% of cell weight, water accounts for 64%, the remaining 4% is lipids, sugars and various electrical dielectrics.
