Book excerpt: "Stuart Fox, Ph.D., wrote the first edition (published 1983) to help students understand the concepts of human physiology, and this objective has remained the guiding principle through all of the subsequent editions. All editions have been lauded for their readability, the currency of the information, and the clarity of the presentation. The fifteenth edition continues this tradition by presenting human physiology in the most current, readable, and student-oriented way possible. This milestone edition is marked by a unique cover, the addition of a Digital Author, a new art program, and the updating of terminology and content. It takes a village! To create this landmark fifteenth edition, Stuart had the support of Krista Rompolski as the Digital Author and a superb team at McGraw-Hill Education and MPS Limited. This team includes Michael Ivanov, Fran Simon, Andrea Eboh, Kelly Hart, Jessica Portz, Christina Nelson, Joan Weber, Angela FitzPatrick, Amy Reed, Jim Connely, Kristine Rellihan, Matt Backhaus, and Lori Hancock. We are all incredibly grateful to the many reviewers who provided their time and expertise to critically examine individual chapters and be Board of Advisor partners. These"--
