It washes the cells for internal purification. The liquid is collected from all organs, poured into the lymphatic vessels, and then into the total bloodstream.

The functions of the lymphatic system are not only the production of lymphocytes that destroy bacteria, but also the provision of a uniform distribution of fluid in the tissues.

Lymph nodes are scattered throughout the body. They resemble small-sized beans from dense tissue that are practically not probed through the skin if they are not enlarged. Their size varies from a few millimeters to several centimeters. They are concentrated in different areas of the body and interfere with the development of the inflammatory process, and even oncology.

In people who have a dense physique andloose skin, lymph nodes can increase for no apparent reason. If soon the phenomenon passes, there is no need to worry about it. And we will consider below the symptoms and causes of enlarged lymph nodes.

So, the main causes of enlarged lymph nodes. This kind of lymphadenitis can manifest even after a common cold with a complication. But most often lymph nodes get infections from the wound on the foot or foot, if there is a purulent process. This is due to the fact that the lymphatic pathways are located in such a way that the infection easily gets from the damaged area to the lymph nodes.

Complication of such a "journey" may becomepurulent abscess in the popliteal fossa, if the microbes caught in the lymph are particularly active. In this case, the intervention of the doctor is necessary - he must open the abscess, which struck the lymph node on the leg, in an operative way, to provide drainage of pus. In medical practice, there are cases when there is no pus inside. In this case, doctors prescribe medication.
