7. The immune response. In this exercise you will be tracing two invaders: bacteria in the extracellular fluid that enter the lymphatic vessels and virus-infected cells in the blood. You will trace the main pathway and the main immune response to the invading organism. Start: bacteria in the extracellular fluid ? bacteria damage local macrophages and damage macrophages release, attract bacteria travel through node macrophages to ? and virus-infected cells enter. to the area ? neutrophils ingest and secrete ? bacteria enter the lymph capillaries ? which Start: virus-infected cells in the blood ? viruses damage tissue and damage cells release attract in the ? then enter ? bacteria encounter macrophages in lymph bacteria macrophages present antigens which differentiate into proliferate and release ?virus-infected cells encounter ? _ingest infected cells ? macrophages present antigens to ? _proliferate ? these cells infected cells.

In this exercise you will trace the pathway of lymph flow from the starting point to the point at which the lymph is delivered to the CV 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.
