Human Physiology & Health Course Human Physiology & Health is the study of human beings - the structure of our bodies, the way they work (and sometimes go wrong!) & the way in which we are related to other living things. It is much the same thing as Human Biology. However, less emphasis is placed on the importance of comparing human attributes with those of other organisms, & on examining our relationships with them. More emphasis is placed on the physiology of the human body, & the way in which we are able to perceive & react to our environment.
