Physiology I

Each type of life, from the simple virus to the largest tree or the complicated human being, has its own functional characteristics. The goal of physiology is to explain the physical and chemical factors that are responsible for the origin, development, and progression of life. Therefore, the vast field of physiology can be divided into viral physiology, bacterial physiology, cellular physiology, plant physiology, human physiology, and many more subdivisions. Our primary goal is the human physiology study of the state of relative stability of the body’s internal environment. These processes feedback systems, that helps to restore the conditions needed for health and life. Our fascinating journey through the human body, begins with an overview of the meanings of anatomy and physiology, followed by a discussion of the organization of the human body and the properties that it shares with all living things. Next, you will discover how the body regulates its own internal environment; this unceasing process, called homeostasis. We introduce vocabulary that will help you to speak about the body in a way that is understood by scientists and health- care professionals alike.
