A learning framework within the book Learning Outcomes appear at the beginning of every chapter to provide a learning framework for students, allowing them to easily test their knowledge after reading. The Digestive System and Reproduction and Development chapters have been heavily revised to include the latest research and better foster student understanding and application. Building off of the engaging ESSENTIALS and REVIEW figures of the Sixth Edition, the Seventh Edition includes more process art, blending narrative explanations and clear visuals that better enable students to visualize difficult concepts and physiological processes. The Seventh Edition’s upgraded art program includes more three-dimensional art and many conceptually redesigned or new figures to enhance student understanding ANATOMY SUMMARIES show the anatomy of a physiological system from a macro to micro perspective in one large spread. Reflex pathway maps and concept maps demonstrate at-a-glance complex physiological processes. REVIEW figures visually present concepts that students should already be familiar with and must master before moving into later chapters and content. ESSENTIALS figures concisely present important concepts for students to master in each chapter. FOCUS ON figures highlight the anatomy and physiology of important organs, including the skin, the liver, the spleen, and the pineal gland. Running Problems are popular case studies based on real-life events that appear in short segments throughout each chapter, providing clinical applications relevant to chapter material. Three chapters on Integrative Physiology (Chapters 13, 20, and 25) ask students to step back and look at the big picture to learn how separate physiological processes work together in an integrated system. These chapters also widen the narrative focus to explore how body systems influence each other and demonstrate the emergent properties of the various body systems.   Engaging Pedagogy Supports Critical Thinking Updated coverage throughout includes information based on recent discoveries. Some controversial ideas and hypotheses are presented, illustrating that physiology is a dynamic, changing discipline. Figure and Graph Questions in select figures and graphs ask students to think critically and analytically, providing frequent stop-and-think opportunities on important concepts. Concept Checks at the end of chapter subsections test students before they move on. Dr. Silverthorn’s end-of-chapter, 4-level learning system helps build student confidence and understanding through a logical progression from factual questions to conceptual problems to analytical exercises to quantitative questions. Level 1 questions review basic facts and terms. Level 2 questions test the student's ability to comprehend and integrate the key concepts in the chapter. Level 3 exercises are real-world scenarios designed to develop problem-solving skills. Level 4 questions are quantitative questions that require mathematical skills.
