Metabolism. The process by which cells are nourished through 

 he assimilation of food, while other cells are broken down to pro- 

 duce energy and heat, is called metabolism. 



Even if we do not take nourishment enough, metabolism con- 

 tinues, thus using up the cells faster than they are built up. It is 

 absolutely necessary that the process of metabolism be well balanced 

 to keep the body in good condition.
