Introduction
Lymph nodes are small glands, the size of beans, which filter lymph circulating through the lymphatic system. They store white blood cells that are responsible for the body’s immunity. Therefore, it’s an important part of the immune system. In fact, those glands trap invading organisms to stop them from infecting other parts of the body. Those nodes can become swollen as a result of infections from bacteria or viruses, though rarely of tumors. Lymph nodes are located everywhere throughout the body mainly on the neck, the armpits and the fold of the groin. They can swell in response to infections in the areas where they are located.
In this article, we are going to focus on swollen neck lymph nodes or cervical lymphadenopathy which are classed as one of the most common lymphadenitis.
