  • Begins with a description of the relationship between the circulatory and the lymphatic systems. The composition of lymph and its movement through the body is explained. Live-action photography shows the flow of lymph through the lymphatic vessels as well as the non-return valves. While the transport of dietary fat is discussed live-action photography reveals the lacterals of the small intestines. A final sequence illustrates the structure of the lymph nodes and the production of both lymphocytes and macrophages. The ingestion of harmful particles by the macrophages and the creation of antibodies in the lymphocytes are examined in detail.
