Study Guide (Transcripts/Summaries):
The lymphatic system is made up of an intricate network of vessels that connect hundreds of lymph nodes as well as several key organs of the immune system. The organs of the lymph system filter the lymph and assist with immune function. Lymph nodes are located throughout the body and are clustered near strategic vein locations such as the elbow, knee, chest, neck, groin, armpits and abdomen. Lymph is interstitial fluid that is collected by specialized lymph capillaries that are located just under the skin and surrounding internal organs. Lymph fluid flows in just one direction, beginning at the tissue cells and moving towards the neck where the fluid empties into veins.
