Digestion is the chemical and mechanical breaking down of the food from large bulks into small components by digestive system. This process as a whole are called catabolism. Those breaking down components will be absorbed at the end of this system, in small intestine. The profit of this breaking down of the process is to get the energy that the body needs to do its activity. However, if the individual wants to be healthy, he should be healthy in his eating.
The digestive system is verified within the organisms. In general we can classify the digestive system into two parts, major organs and accessory organs. Food passes through the major organs. On the other hand, accessory organs help the digestive process through some its function, for intestine, secrete enzymes.
