We will study the structure and function of the human body. To begin with, we will examine the concept of homeostasis.
Homeostasis is the maintenance of a relatively constant internal environment.
Disease can be described as a loss of homeostasis in one or more systems of the body. In order to understand how the body works as a whole, we have to examine the functioning of body systems at several levels. We begin with a brief overview of chemistry and cells. Once we understand how cells function as the smallest unit of life, we will next examine the organization of cells into tissues, organs, and organ systems. In order to understand disease, you need to understand the inter-relationships between different body systems.
