Lymphatic System

The video explores the lymphatic system, a lesser-known body system often linked with the immune system. It explains the role of lymph, derived from blood plasma, and its journey through lymphatic capillaries, vessels, and ducts. The lymphatic system's close relationship with the circulatory system is highlighted, as well as its role in immune function through lymph nodes, which filter pathogens and house immune cells. The video also covers lymphatic organs like the spleen and tonsils, and discusses primary lymphoid organs where lymphocytes develop. Finally, it addresses potential malfunctions of the lymphatic system, such as lymphedema, and related diseases.
