Lymph nodes are round and oval in shape (with some variations), they are pinkish gray and have a size of 0.5 to 50 mm. (this depends on the body weight). They are clustered up to 10 pieces near the blood vessels, most often near large veins.
The role of lymph nodes in the human body is enormous,because it is the most effective barrier that protects the body from infections and cancers. In these nodes, lymphocytes are formed - special cells involved in the destruction of foreign bacteria and microbes.
