What are Lymph Nodes?
The lymphatic system is a network of tissues/glands, organs, and channels throughout the body. This system transports lymph, a clear fluid containing lymphocytes, white blood cells that are one of the body’s main types of immune cells that help your body fight infection and illness. There are hundreds of lymph nodes in the body, many of which are in the neck, whose function is to filter the lymph. The lymph nodes stop bacteria, viruses, and diseased cells from passing the nodes and continuing throughout the body via the lymph vessels.
