1) "Refresh Your Memory" boxes at the start of chapters alert students to material covered in previous chapters that they may need to review as they begin a new chapter.
2) Take Advantage of the Technology boxes acquaint students with the wide range of resources available on the text website and within the Multimedia Applications, to complement each chapter in the textbook.
3) Clinical Investigations are brief case studies presented at the beginning of the chapters to present a fascinating puzzle. Clues to solving the case are given along the way, as each relevant piece of information is presented.
4) Clinical and Fitness Applications boxes help students understand physiological concepts through medical and exercise applications.
5) Test Yourself Before You Continue questions are placed at the end of every major section so students can quickly assess whether they are ready to move on to the next section.
6) Interactions pages provide cross-links (with page references) to information in other chapters of the book. The page references are similar to hyperlinks on the internet, and are called HPer Links (a hybrid of hyperlinks and the initials of Human Physiology).
7) Review Activities at the end of each chapter are organized into three learning levels: Knowledge of Terms and Facts, Understanding of Concepts, and Analyze and Apply your Knowledge. This graduated approach is designed to assist students as they progress from memorization to higher levels of understanding.
