The lymphatic system performs several key functions, including:
Fluid balance: It helps maintain the balance of fluid in the body by collecting excess interstitial fluid and returning it to the bloodstream.
Immunity: It plays a crucial role in the body's immune response by filtering and trapping foreign particles, such as bacteria and viruses, in the lymph nodes.
Tonsils: These are clusters of lymphoid tissue located in the throat that help protect against infections entering the body through the nose and mouth.
Disorders of the Lymphatic System
Some common disorders of the lymphatic system include:
Lymphedema: This condition occurs when the lymphatic vessels are unable to adequately drain lymph fluid, leading to swelling, particularly in the arms or legs.
Lymphoma: This is a type of cancer that affects the lymphatic system, particularly the lymphocytes, which are white blood cells involved in immune function.
Tonsillitis: Inflammation of the tonsils due to infection, often resulting in sore throat and difficulty swallowing.
