The ninth edition of Seeley’s Anatomy and Physiology is the result of extensive analysis of the text and evaluation of input from contributing authors and instructors who have thoroughly reviewed chapters. We are grateful to these professionals and have used their constructive comments in our continuing efforts to enhance the strengths of our textbook.

Learning Outcomes and Assessment
• Learning Outcomes are carefully written to clearly outline expectations
• Assess questions assist with course measuring standards and student comprehension

CONNECT w/ LearnSmart® — Making teaching easier and learning smarter
A personalized cognitive mapping learning system, LearnSmart tailors study time and identifies at-risk students:
• Deliver and track your assignments, quizzes, and tests easily online
• Use various ready-to-go Lecture PPTs for instructors, including embedded animations—or make your own using McGraw-Hill art
• "Flex" art—take it apart and build it back during lecture
• 24/7 eBook access with animations, videos, and practice quizzing

Fundamental Figures—Integrated with special Connect assets!
• Key figures to understanding the chapter are highlighted as Fundamental
• Additional online Connect resources support these important figures
• Grouped together, the Fundamental Figures represent an excellent summary and study tool

Learn to Predict and Learn to Predict Answer
• Part of the critical thinking Predict questions that appear throughout each chapter, a Learn to Predict question now opens every chapter and is specially written to take knowledge acquired from previous chapters, and tie it into content in the current chapter.
• A new Learn to Predict Answer box at the end of each chapter teaches students step-by-step how to answer a higher application question. This is foundational to real learning and is a critical part of helping students put facts together to reach that "Aha" moment of true comprehension.

Homeostasis Summary Figures
These specialized flowcharts illustrating the mechanisms that body systems employ to maintain homeostasis have been refined and improved in the ninth edition:
• More succinct explanations
• Small icon illustrations included in boxes visually represent the organ or structure being discussed
• Less clutter with multiple arrows—easier to follow

Reorganization and Enhancement of Chapter 17
• One of two Endocrine chapters, Chapter 17 has been reorganized and rewritten so that the hormones are grouped by chemical make-up, allowing the student to follow the content in a more logical fashion. For example, when students now read about classes of receptors, the content will be divided into the two major groups of hormones (hydrophilic and lipophilic), followed by specific examples of each mechanism of action. Reviewers have been delighted with this reorganization as it matches the way they teach the chapter.
