The Lymphatic System and Immunity Functions and Structures: 1. LYMPH- watery fluid that goes between capillary blood and tissues - transports pathogens to lymph nodes where they can be destroyed - INTERSTITIAL FLUID filters out of capillaries into the microscopic spaces between cells 2. LYMPH VESSELS- transport excess tissue fluid back into circulatory system. 3. LYMPH NODES- produce lymphocytes, filter out harmful bacteria.
