Lymphatic System (Lecture) Flashcards
Describe the flow of lymph from the upper and lower left quadrant and the lower right quadrant of the body
Lower quadrants go through the cisterna chyli. Then the cisterna chyli and lymphatic vessels from the upper left quadrant empty into the thoracic duct which empties into the L. SCV and L. JV
Describe the flow of lymph for the upper right quadrant of the body
Lymphatic vessels in that quadrant empty into the R. lymphatic duct which empties into the R. SCV and R. JV
What vessel is being emptied and where is it emptying to?
Right Lymphatic duct into right Subclavian Vein
What vessel is being emptied and where is it emptying to?
Thoracic duct into left subclavian vein
