"Did you sign up for Anatomy and Physiology? Are you terrified yet? If so, join the masses of students each term who are terrorized by the very idea of taking such a daunting course. I wrote this book to show you that science does not have to be terrifying! It can be downright intriguing, better yet, empowering! That is, if you can get past all the high sounding jargon. Don't get me wrong, I'm a fan of high sounding technical vocabulary, but I believe that without understanding the basics at an everyday, relatable level, we can never achieve understanding of the complicated physiological concepts. This book will bring some of the more confusing concepts of introductory physiology down to a relatable, everyday level. It will give you the tools you need to grasp these concepts as you move on in your scientific or pre-professional upper level courses. This book is meant to be used as a supplement alongside your textbook as you maneuver through some of the more challenging physiological processes. Come on, RELAX, you can do this!"--Page [4] of cover.
