Immunology provides the medical student with an excellent first step onto the medical student's path of lifelong learning about the immune system. The book is organized in two parts. In Part I, The Basics, clinical cases provide examples of what happens during an immune response, and why, and emphasize the relationship between the immune system and other organ systems. Part II, Learning Issues, builds on those basic concepts and comes to grips with common difficulties students experience in learning about the immune response.
