The document summarizes key aspects of the lymphatic system: 1) The lymphatic system is made up of lymphatic vessels, tissue, and organs that circulate a colorless fluid called lymph throughout the body. 2) The lymphatic system contains primary and secondary lymphoid organs. Primary organs include the bone marrow and thymus where lymphocytes develop. Secondary organs include the spleen and lymph nodes where lymphocytes collect and immune responses occur. 3) Lymphocytes contain two main types of immune cells - B-cells and T-cells - as well as natural killer cells, which are subtypes of white blood cells important for immune function.
