"Physiologists," says the author, "are like children throwing rocks into a pond. The children want to see what kind of splash the rocks make upon entering the water, but they also want to know where the ripples go and what happens when one ripple encounters another." This sense of wonderment and exploration that fuels Dee Silverthorn's interactive, case-oriented classes, has given birth to the second edition of her innovative text, Human Physiology: An Integrated Approach. As in the first edition of her text, Silverthorn goes beyond simply presenting the material - she asks her readers to experience physiology and understand the themes that drive the complexities of our bodies. Familiar active learning and integration features from the first edition include: Macro-to-micro artwork; Anatomy Summaries that provide an illustrated anatomical overview; Chapter outlines and chapter summaries; Running Problems - Extended problems that ask, "How does the material apply to life situation?"; Integrated chapters - Coordinate the information and form a more complete understanding; Reflex pathways and concept mapping - Organize themes and coordinate the details; Graphing questions - Question to help you practice reading and interpreting graphs. Additional learning features added for this edition: Diabetes Boxes - Using diabetes as an extended example of physiological integration, select chapters have Diabetes Boxes that highlight the effect of diabetes on body systems. Active learning through media - MediaLabs promote active learning focused on Internet exploration. Readers are directed, via the free Silverthorn Website, to gather information that applies to the problem at hand. Increased focus on quantitative problem-solving - The three-level learning system from the first edition has now become four levels, with the new Level Four end-of-chapter questions focusing specifically on quantitative problems. Come see for yourself why Silverthorn's Human Physiology has everyone talking.
