Basic Physiology: Understanding the Signals Our Bodies Send

Vital signs - heart rate, blood pressure, body temperature, respiratory rate and pain sensation - convey important information about the physiological state of the human body. In this six-part course, we will examine the anatomy and physiology behind vital signs so that you will have a systematic, comprehensive understanding of how the body functions. The relevant body systems, including the cardiovascular and respiratory systems, are reviewed and then how the functioning of these systems affects vital signs are explained. We will discuss normal ranges, variations in normal ranges and the mechanisms underlying changes in objective measurement of vital signs. The course also includes demonstrations of appropriate techniques for measuring vital signs in yourself and others. The course is designed for a general audience, but will be of particular interest to people working in healthcare, those considering a career in healthcare, those involved in nursing, those interested in personal health and fitness, or anyone who simply wants to understand how the body functions.
