Excerpt from The Elements of Physiology for Schools The human body is made of cells and its life consists in the activities of the cells. Physiology is the study of the cells and tissues in their related activities. Yet the usual school physiology neglects the functions of the cells and tissues and studies organs almost as isolated things, rather than as component parts of the bodily structure. The well organized science of physiology is thus slighted and the result is an unnecessary waste of time. The experience of the author with young students has convinced him that elementary facts in the science are not so difficult of comprehension when given in their real relations as when given as isolated facts.
