Lymphedema Management Exam Questions With 100% Correct Answers What does the lymphatic system do? - answerDrains fluid from interstitial tissues and brings it back to the blood stream How many liters does it move a day? - answer2-3 liters What is lymph fluid made of? - answermainly water and protein but also misc cells and fat What does lymphatic load mean? - answerfluid that can't be drained or reabsorbed by the blood system What are the duties of lymphatic system? - answer-continuous circulation of fluid in interstitial space -safety valve for fluid overload -balance of protein and water (homeostasis of extracellular environment -cleansing of interstitial fluid How thick is lymphatic system? - answer1 epithelial layer thick What is the smallest component in lymphatic system? - answerlymphatic capillaries How does fluid get into the lymphatic system? - answerlymphatic capillaries are connected by anchoring filaments. With fluid build up tissue pressure increases pulling on the filaments. This opens the jx btw cells and lymphatic fluid enters the system through this opening Trace lymph fluid travel starting from lymph capillaries to lymph nodes? - answerTravels from capillaries to lymph pre-collectors. From pre collectors goes to lymph collectors. Then lymph is transported through collectors via muscle contraction of the lymph anions. When fluid enters the lymph angion - muscle is stretched causing muscle to contract. fluid enters nodes via afferent lymph collectors and leaves via efferent lymph collectors What do lymph pre collectors look like? - answerclosely related to blood vessels with a layer of smooth muscle and valves that allow uni-directional flow T or F. Does lymph have its own flow rate? - answerTrue. What's another name for the lymph angion? - answerthe heart compartment What is another name for angiomotoricity? - answerlymph pulse What is the contraction frequency of lymph angion when at rest? under stress? - answer6- 10 per min at rest 20 per min during stress What are the two primary functions of lymph nodes? - answerProtection - filter out harmful material in lymph fluid Immune Response - produce lymphocytes Where are lymph nodes located? - answerneck, digestive system, axilla, and groin Approximately how many lymph nodes in body? - answer700!!!!
