FUNDAMENTALS OF PHYSIOLOGY, Third Edition, is based on Lauralee Sherwood's best selling Fifth Edition of HUMAN PHYSIOLOGY: FROM CELLS TO SYSTEMS. While both texts cover the same key topics in a current, engaging, and clinically relevant manner, FUNDAMENTALS OF PHYSIOLOGY is briefer, lower in level, and requires less of a background in chemistry, physics, and math than its sister text. Essential content is organized around the central theme of homeostasis, as demonstrated by the system-specific homeostatic model that opens each chapter, as well as the "Focus on Homeostasis" that completes each chapter. New to this edition are process-oriented figures, created to aid today's visual learners. These figures include step-by-step descriptions summarizing and integrating various aspects of essential concepts. Another noteworthy addition is the comparative and early introduction of "Principles of Neural and Hormonal Communication"-a NEW Chapter 4. This edition also showcases an emphasis on real-life experiences, using analogies as well as new "Clinical Note" icons, which flag clinically relevant material. The text is also supported by PhysioEdge 2-arguably the best student CD-ROM on the market-which ties concepts and art together with narration and animation. This free CD-ROM has been revised to include new media exercises and tutorials, and is integrated with this Third Edition to encourage students make optimal use of the available media. Instructors are likely to find indispensable our Multimedia Manager with Instructor Resources-a CD containing ALL line art from the text, over 40 animations, electronic versions of instructor materials, and Microsoft PowerPoint lectures.
