This is an approachable, modern, and comprehensive presentation of immunology that helps undergraduate students see the big picture without feeling overwhelmed. Immunology , Second Edition, provides an easy-to-follow introduction for aspiring professionals in research, medicine, and other health professions. In a course where students often get lost in the vast amounts of detail, terminology, and the sheer complexity of the immune response, this text uses an approachable narrative and exceptional illustrations that present the exquisite details of immunology. Unique features, including "Making Connections" figures, use annotated illustrations, videos, and exercises to relate material to key concepts and mechanisms learned in previous chapters. This emphasis on visualization, along with multimedia and interactive elements, emphasizes the connections between key themes, helping students see the big picture of the immune response, and empowering them to move beyond rote memorization to foster a deeper understanding of how we know what we know--and why. This new edition introduces exciting enhancements based on the valuable feedback from the Immunology Advisory Board and dozens of reviewers--including all-new animations, Interactive Human Health Connection modules, Biology Review Videos, and an Immunological Methods Appendix--all available in Oxford Insight courseware. These resources, alongside case studies, interactive figures, "Think About" questions, and a comprehensive array of additional pedagogical elements encourage active learning and critical thinking.
