BIOD152 Anatomy and Physiology II Quiz #5: Module 5 Question 1 Not yet graded / 0 pts Anatomy of the Lymphatic system 1. The lymphatic system is closely connected with what other body system? 2. What are lymphatic vessels? 3. What are three functions of the lymphatic system? 4. What is lymph? 5. Describe the flow of lymph. 6. True or false: Lymph vessels are only found in the lower extremities. 7. Describe the structure of lymph vessels. 8. Label the thoracic duct and the right lymphatic duct. Your Answer: 1. cardiovascular 2. vessels that take up excess fluid and return to the bloodstream 3. Helps with fluid regulation in intracellular space, helps with immunity, and absorption and transport of fats. 4. excess tissue fluid entering lymphatic capillaries. 5. lymph flows in one direction, from the periphery of the body towards the cardiovascular system 6. false 7. one way flow valves, and are dependant on muscular movement for transportation of fluids. 8. 1. Cardiovascular system 2. The lymphatic vessels take up excess tissue fluid and return it to the bloodstream 3. (1) The lymphatic vessels take up excess tissue fluid and return it to the bloodstream. (2) Lymphatic capillaries absorb fats and transport them to the bloodstream. (3) The lymphatic system helps with immunity to defend the body against disease. 4. Excess tissue fluid entering the lymphatic capillaries from the interstitial fluid not returned by the cardiovascular system. 5. The lymph flows one way, from the lymphatic capillary system to the subclavian veins, where it joins the venous circulation to return to the heart. 6. False 7. Lymph vessels have one-way flow valves similar in structure to the large veins of the cardiovascular system. The valves prevent the backward flow of lymph. The return of the lymph fluid into circulation is solely dependent on the squeezing action of skeletal muscles, squeezing the fluid one way through the lymphatic vessels. 8. See figure in module Question 2 Not yet graded / 0 pts Anatomy of the Lymphatic system 9. The right lymphatic duct drains into the ________. 10. True or false: The thoracic duct drains fluid from the right arm. 11. Describe the structure of a lymph node. 12. What is the axilla region? 13. The spleen is in what region of the body? 14. What is the function of the spleen? 15. After blood exits the spleen via the splenic vein, where does it travel?
