Ganglions - Definitions

Ask a question
The ganglions (lymph nodes) are small rounded bodies scattered throughout the body in the path of the lymphatic circulation. They are like small swellings where a large amount of lymph can accumulate.

Lymph is a biological fluid that contains many cells involved in defending the body, including leukocytes, or white blood cells.

The main function of the lymph is to ensure the immune defense of the body, mainly by producing antibodies in case of recognition of a foreign agent and releasing them into the bloodstream.

Usually measuring not more than one centimeter in diameter, the number of nodes in the human body can grow under the action of various diseases and more or less severe infections.
