Lymphatic and Immune Systems 1. . lymph leaving the cisterna chili contains fat while lymph entering the right lymphatic duct doesn’t 2. palatine tonsils 3. .lymphatic capillaries are much larger than blood capillaries and only have 1 way openings 4. . The thymus of the fetal pig or young cat is very large compared to an adult. The thymus regresses with age and is replaced by adipose tissue. 5. .So they can absorb better 6. .because the lymph vessels have valve openings 7. . Yes. Lymph nodes have lymphatic vessels leading into them that would drain the axillary area around the lymph nodes of excess interstitial fluid. When these structures are removed, excess interstitial fluid may build up. 8. . Slower than blood capillaries due to the lymph node structure. Each lymph node has more afferent vessels entering it than efferent vessels leaving it. This slows lymph flow through the node. 9. . Bacteria, viruses, worn out cells, and other debris engulfed by macrophages. 10. . Bacteria entered the body through the small cut between the toes and traveled up the lymphatic vessels of the leg into the inguinal lymph nodes. Lymph travels through the lymph nodes slowly, allowing phagocytosis to occur by macrophages. The increased number of bacteria in the lymph nodes causes swelling. 11. . A person contracts elephantiasis when an infected female mosquito transfers parasitic worm larvae to the human's body fluid as it bites and draws blood. 12. . The parasite worm lives in the human's lymph system, causing severe edema by blocking the lymph flow. The immune response to this foreign parasite can also cause fever, chills, headache and pain.
