Describe the formation of lymph within that region, relating that to blood vessels within the region and addressing the physical forces that lead to lymph production. How would the lymph that is formed in that region be returned to the blood supply? What vessels and lymph organs would it travel through? Also, imagine that there is a potential pathogen within your identified region - what involvement of other lymph organs or individual immune cells would you expect?
