Lymphatic System: Key Roles in Fluid Balance & Immunity

One of the main roles of the lymphatic system is to collect and return interstitial fluid to the bloodstream.

- Interstitial fluid, also known as tissue fluid, is fluid that fills the spaces between cells in tissues and organs.

- The lymphatic system collects this fluid and returns it to the bloodstream, helping to maintain fluid balance and prevent edema (swelling).

- The lymphatic system also plays an important role in immune function, helping to protect the body from infection and disease.
