In this procedure, you’ll trace the pathway of lymph flow from the starting location to the point at which the lymph is delivered to the cardiovascular system. You will trace the flow through the major lymph-collecting vessels, trunks, and ducts, and highlight clusters of lymph nodes through which the lymph passes as it travels. 1. Write the sequence of the flow. 2. Then, use differently colored water-soluble markers to draw the pathway on a laminated outline of the human body. If no outline is available, use colored pencils and In-Lab Figure 21.2
