The lymphatic system is a network of tissues and organs. It is made up of:
Lymph - a fluid that contains white blood cells that defend against germs
Lymph vessels - vessels that carry lymph throughout your body. They are different from blood vessels.
Lymph nodes - glands found throughout the lymph vessels. Along with your spleen, these nodes are where white blood cells fight infection.
Your bone marrow and thymus produce the cells in lymph. They are part of the system, too.
The lymphatic system clears away infection and keeps your body fluids in balance. If it’s not working properly, fluid builds in your tissues and causes swelling, called lymphedema. Other lymphatic system problems can include infections, blockage, and cancer.
