Book excerpt: This carefully developed new text addresses the key challenges that instructors face in teaching students with varied backgrounds and learning styles. The authors incorporate numerous integrative features--such as systems integration charts and an integrative exercise physiology chapter--to help students take what they learn on the cellular, chemical, organ, and system levels and apply it to the body as a whole. This technique weaves a relevant, concrete body systems integration theme throughout the book, helping students to build on their knowledge.
