Describe one way in which they are similar and one way in which they are different B. Given that lymph vessels carry lymph under very low pressure, they require assistance in moving lymph, especially vessels below the level of the heart which must move lymph upwards against gravity. The 2 mechanisms which assist in the flow of lymph are contraction of surrounding skeletal muscles and ventilation (breathing). Explain how each mechanism assists in the movement of lymph. C. Describe why lymph vessels need valves to maintain the flow of lymph in one direction. Arteries of the cardiovascular system also move blood in one direction but they don't need valves -why not? TOPIC: Collecting Ducts A. From which regions of the body does the Thoracic Duct receive lymph? From which regions of the body does the Right Lymphatic Duct receive lymph? B. The collecting ducts deliver lymph to the bloodstream by merging with and dumping lymph into the bloodstream at the right and left veins C. The digestive tract has its own collection of lymphatic vessels which function to absorb digested fats and transport them via lymph into the bloodstream. What are these lymphatics called? Why are most dietary fats absorbed into lymph capillaries rather than blood capillaries (which absorb carbohydrates and proteins)?
