The Digestive System is a system that prepares food particles for their entry into the bloodstream. Digestion involves breaking organtic compounds into simple soluble substances absorbable by tissues. It also includes both mechanical and chemical processes. The mechanical processes includes chewing and reduce food into small particles. These forces move through the digestive track and mix it with various secretions. There are three chemical reactions that take place. They are the conversion of carbohydrates into simple sugars like glucose, breaking down of protein into amio acids, and the conversion of fats into fatty acids.
