This six-week online course begins with an explanation of the nature of matter and a review of the principles of chemistry that are important to human physiology. We'll place an emphasis on the organization of the human body and the differences between nonliving matter and living organisms. We'll also cover cell anatomy and physiology because all life processes are ultimately carried out at the cellular level. You'll also learn principles of genetics and gain an understanding of how traits are passed from one generation to the next. This course explains how the circulatory and respiratory systems work together to provide our bodies with the oxygen our tissues need, and how they work together with the skin and kidneys to rid our bodies of wastes. You'll learn how our bodies fight off diseases, and how our digestive system converts the food we eat into energy and the tissues of our bodies. We'll also spend time on the endocrine system, which supplies the hormones we need for our survival, and the reproductive system, that group of organs that allows life to be passed on to another generation. In addition, each lesson includes information about specific disorders that sometimes happen to our bodies, and we'll also talk about some recent advances in medicine. By the end of this course, you'll have a greater appreciation and understanding of the marvelous complexity of the human body!
