Lymph in Greek means " Lymphatic vessels meet lymph nodes in their path. What is the function of the lymph nodes?

Collection and filtration Each human body has from 400 to 1000 lymph nodes located on the folds of the limbs, under the jaw, in the neck, in the cavity of the chest and abdomen. Cells of the immune system mature in the lymph nodes. In each node, lymph is continuously collected from a certain area and filtered from substances unsuitable for the life of the body: foreign proteins, defective cells, parasitic microorganisms.

An admixture of harmful substances enters the lymph node, and what happens to it next? Pathogenic cells are attacked by immune cells that destroy pests entirely. If inflammation occurs in the tissues that conduct lymph, the load on the lymph node increases.. It may enlarge or become inflamed.. With the cessation of the disease, the lymph node decreases, but becomes slightly denser than before the disease..

There can be several hearts. The liquid component of blood from the capillaries enters the intercellular space and forms lymph.. Lymph, before entering the lymphatic vessels, washes the tissues, and from the vessels enters the veins. Some amphibious animals and birds in the body have such tissue structures called " These tissues have muscles that move the lymph in one direction.. There are no such "

In babies who have not yet had diseases in life, the lymph nodes under the skin are so tiny that they cannot be felt.. But, probably, there is not a single adult who has not had at least colds..

Lymph nodes in adults can be found by touch under the jaw and on the neck. Often people do not have noticeable lymph nodes in the folds of the limbs, they remain the same size as in young children.. It is not easy to detect nodes if there was no inflammation on the arms and legs before. Filters located in the tissues of the chest or abdominal cavity are not always able to be identified even by an experienced doctor..

Characteristics of the lymph node When examining the lymph nodes, the doctor analyzes all their properties: size, pain, degree of interconnection of the nodes between themselves and nearby tissues. These qualities help to establish an accurate diagnosis..

• Enlarged lymph nodes, in which there is no pain, indicate a disease of the surrounding tissues. This disease is called lymphadenopathy..

• Painful enlargement of a lymph node is called lymphadenitis and indicates inflammation within the node itself. The filter of our body in this case is not able to defeat harmful bacteria and is attacked by them.. In this case, the immunity may not be strong enough, or the reason is the strength of the infection.. This condition is dangerous by the occurrence of suppuration. Pus, forming phlegmon, can spread between tissues, and only surgery is required to remove it.

• With strong compaction and association of lymph nodes into a sedentary system, doctors have every reason to suspect a malignant tumor.

Human Cancer Cells About 100,000 cancer cells are formed in the human body every day.. Due to a genetic failure, the properties of cells change, and their reproduction is not restrained by anything.. Their difference is the ability to easily separate from the place where they originated and travel through the tissues of the body.. First of all, they seep into the lymph and are neutralized in the lymph nodes.. A person with a cancerous predisposition of defective cells produces as many defective cells as any person, but the ability of the lymph nodes to neutralize cells is reduced. Immune cells act in the same way in tissues, incapable of searching for harmful impurities and destroying them..

Weakened immunity With a sore throat, local lymphodynamia occurs in the neck, and with genital infections, hypodynamia occurs in the groin area. There are diseases that provoke a widespread increase in lymph nodes, such as, for example, with AIDS. It can be assumed that lymphodynamics is a positive symptom, meaning that the immune system is actively involved in the fight against the immunodeficiency virus, but it cannot be denied that lymphodynamics can portend a life-threatening disease.. In the process of AIDS infecting the human body, the immune system wears out, and the lymph nodes lose their ability to resist cancer cells and harmful bacteria and microorganisms.. Those infected with HIV can die, not because of the attack of the virus, but because of the harmful effects of infections and tumors..

There is no panic here. Enlarged lymph node indicates a working immune system. To find out for what reason the node was activated, you should visit a specialist. There are many reasons, and sometimes it is enough to have rhinitis or caries, or even just a cat scratch on the skin, in order to activate immunity protection. Only thanks to a specialist can one assess the real risk to health by examining all the symptoms. The lymphatic system often does not need any treatment at all, all that is needed is to treat a tooth or a sore throat. Over a lifetime, a person’s lymph nodes can increase more than once, and this phenomenon can be taken without fear..
