Picking up where A&P I left off, in Anatomy & Physiology II you focus on the major parts of the body and how they work independently as well as together. Start with the cardiovascular system. Next, explore the lymphatic system, immunity and the three lines of defense the body has against pathogens. Then it’s on to the respiratory, digestive, and urinary systems as well as nutrition, metabolism and body fluid balances. Finally, you will study the male and female reproductive systems as well as stages of human development, growth and aging.
