What is the lymphatic system?
Human BodyImmune System
Quick Answer
The lymphatic system is a network of vessels, nodes, and organs that helps drain tissue fluid and support immunity. It returns excess fluid to the bloodstream and helps fight infection.
The Full Story
The lymphatic system includes lymph vessels, lymph nodes, the spleen, thymus, tonsils, and other tissues. It collects excess fluid from tissues, called lymph, and returns it to the blood circulation. Lymph nodes filter lymph and house immune cells that respond to pathogens. The system also helps absorb fats from the digestive tract through specialized lymph vessels. When lymphatic drainage is impaired, swelling called lymphedema can occur.
