The Lymphatic system is one of the most significant parts of our Immune System.
It consists of a set of slim tubes which are called Lymph Vessels. These tubes divide off into different parts of the body. Lymph vessels carry a liquid known as lymph which is a watery type solution containing white blood cells called Lymphocytes.
Incorporated into the enormous system of lymph vessels in our bodies, are lymph nodes, which are small, bean-shaped organs, divided into groups. Thousands of lymph nodes are discovered in numerous locations in the body. These are the groin, neck, elbows, and under the arms. Lymph travels throughout the lymph nodes and the lymph tubes and various other specialized lymph tissues which include the thymus gland, tonsils, bone marrow and spleen.
The Lymph nodes strain lymph fluid, removing microorganisms, viruses, and other foreign substances. If a great number of microbes and bacteria are filtered through a group of lymph nodes, then they may become distended and sore to touch.
For example, if you have a painful or sore throat, the lymph nodes under your chin and in your neck may swell and become painful. At other times, the lymph nodes in the arm pit may become swollen and tender when an infection is being fought by the body’s defenses.
Most inflamed lymph nodes are a response to disease and infection and are not cancerous.
