Human Digestion Shaunda SCI/241 05/16/14 Human Digestion From what I have learned from the weekly readings and watching the animated digestive tract. When humans digest food‚ we go through a complex process‚ in which the food eaten is turned into energy that is needed in order to survive. During the digestion process the food eaten becomes waste that has to be eliminated eventually. I will discuss how this process works in each area of mouth‚ stomach‚ small intestine

objective of this experiment is to differentiate between a physical change and a chemical change. A physical change includes a change in the material without affecting its composition‚ such as the physical state change. However‚ a chemical change includes the change in the composition of the substance. The change in color‚ formation of a gas or a solid product‚ and the production of energy are the evidences of a chemical reaction‚ thus‚ of a chemical change. Materials Crucible tongs Evaporating

After the food is covered with saliva‚ you then begin to chew your food. Chewing breaks down food into smaller pieces and also breaks apart fiber that
