Lymphatic and Immune Systems
Chapter Outline
8.1 Lymphatic SystemThe lymphatic vessels form a one-way system, which transports lymph from the tissues and fat from the lacteals to certain cardiovascular veins. 146The lymphoid organs (red bone marrow, spleen, thymus, lymph nodes, and tonsils) play critical roles in defense mechanisms. 147 |
