What are lymph nodes?

Our body, like a root system of a tree, is shrouded in thin vessels with nodules on them, along which the lymph is moving - a liquid substance. That's what it is lymphatic system. The place of accumulation of several vessels is called lymph node.

A circulatory system is located next to the lymphatic. She is closed. In the lymphatic system, in contrast to the circulatory, the lymph moves only in one direction: from limbs to the center, and then connects to the central veins, where it “shipping” the spent lymph.

Lymphouzel -This is an oblong elastic formation under the skin or inside the body, having a diameter of 2-5 mm in a calm state, if nothing hurts. If some disease has begun, the lymph node increases to 1-2 cm, but maybe up to 5 cm.

In the section of the lymph node It consists of sections in which lymphocytes are located. If the body attacked a lot of infections, then the lymphocytes in the lymph nodes begin to be intensively produced. Here, in the section, the lymph of the lymph channels also seeps, driving a harmful microbe. In the lymph node, with the help of lymph, the infection understands pieces, and lymphocytes study it in order to then look for throughout the body, and destroy similar microbes.
