This book is designed for students in the Anatomy and Physiology Undergraduate Program. Take a journey to understand the complexity of the structure and its intricate function through pages of concise text, anatomical images, dissection of organs, and short videos. In addition, visualization of 3-dimensional animations has been linked to display relationships that enhance the understanding of particular mechanism or system.  My goal is to provide students the responsibility of “self-learning” and guide students in hands-on laboratory studies of the body to reinforce the information learned in the lecture.
