This book came to complete what was previously published, which was related to the human physiology in general without being defined by specific age group. As said by the other that physiology is the center of galaxy of all medical sciences and all other medical subjects revolve around physiology .Therefore, it was necessary to work to complete what was stated in the book "Introduction to Human Physiology" with the new book entitled "Biological and Physiological Concepts of Aging" that deals with the physiological changes accompanying aging and the effect of aging on the physiology of body systems in the elderly beside the biological bases of aging process .The book includes four chapters. The first chapter is about the concepts of aging in general, which presents the general concepts that clarify the aging processes. The second chapter deals with the causes that result in aging and discussing the different theories that explain aging processes. The third chapter shows the normal changes that occur in different body systems with age in the elderly in simple and brief presentation. Finally the last chapter is about how to improve aging, as an attempt to age in positive and healthy manner. I hope that I have presented the convenient and brief biological and physiological concepts for understanding aging.
