Anatomy and Physiology is a dynamic textbook for the year long Human Anatomy and Physiology course taught at most two- and four-year colleges and universities to students majoring in nursing and allied health. A&P is 29 chapters of pedagogically effective learning content, organized by body system, and written at an audience-appropriate level. The lucid text, strategically constructed art, inspiring career features, and links to external learning tools address the critical teaching and learning challenges in the course. Color is used for pedagogical effect in A&P. Most art will consist of elegant black line, with the strongest line illustrating the most important structure(s) and shading used to show dimension and shape. Color (used only when needed) highlights and clarifies the primary anatomical or functional point of the illustration. Student focus is drawn to the most important learning point in each illustration, without distraction from excessive gradients, shadows, and loud highlights. The online book provides students with links to surgical videos, histology, interactive diagrams, and cadaver imagery at critical junctures.
