Welcome to the exciting and fascinating world of physiology and pathobiology. As an extension to the general health science studies, this book introduces you to the various abnormalities that can occur in humans.The primary motivation for writing this book, "Human Physiology & Pathobiology - A contemporary guide to disease processes" is the lack of a standardized uniformity in the study of pathophysiology to health science students. It is, therefore, my hope, that this book would alleviate the milieu of challenges faced in this discipline. In writing this book, I have also tried to make it vivid, but brief as possible. Since too much brevity may also compromise understanding, the writing has been a bit "liberal" in some sections including some details which are deemed vital for your understanding, and not memorization.Lastly, while this book is intended to be a textbook of general pathobiology and physiology for health science students, medical students and those in other advanced levels of their medical training can use this book for review.
