You are a drop of water that your instructor has taken.  For this assignment you will write the pathway you would follow will the limitations are written below. START with the name of the structure where you would first be absorbed. END with the name of the structure where you would leave your instructor's body. Name EVERY structure through which you must pass between the start and endpoints.  If you get stuck, write something to indicate (such as ....) then continue on the latter part of the pathway.
