HEALTH EDUCATION IN SCHOOLS
Human biology is a detailed and complicated study. Thus, for the purposes of
health education in schools, it is best approached from the point of view of function
rather than structure. The detailed anatomy and physiology of the heart and
circulation, for instance, are not needed, but students should know that the heart's
function improves with use and that regular exercise is the best way to avoid distress
upon exertion. Thus, the basic knowledge required to live
a healthy life is that
oxygen is supplied to the muscles by a partnership of lungs and heart, the lungs
taking in a supply and the heart distributing it. Exercise involves a call for more
oxygen and, if the heart is not trained to deliver a full volume of blood with each
beat, the lungs must work harder to compensate. These simple facts can be
appreciated without the need for elaborate detail.
