The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood. Once in the blood, the food molecules are routed to every cell in the animal's body. There are two types of animal body plans as well as two locations fordigestion to occur.
Both mechanical digestion and chemical digestion are necessary for the digestion of foods and beverages into pieces and molecules that are small enough to be absorbed in the small intestine. Both types of digestion are important and complement each other in the digestive process. There are, however, significant differences in the two types of digestion. Mechanical digestion involves the process of physically breaking down the food into ever smaller parts. The major player in mechanical digestion is mastication, which is the act of chewing and using the teeth to break the food into pieces small enough to be swallowed into the esophagus.
