What system drains fluid from the tissues?

The lymphatic system is responsible for draining fluid from the tissues. It collects excess interstitial fluid, which is the fluid that surrounds cells, and returns it to the bloodstream. This process helps maintain fluid balance in the body and plays a crucial role in immune function by filtering out pathogens and debris. The lymphatic vessels transport lymph, the fluid within the lymphatic system, toward lymph nodes and ultimately back to the circulatory system.
