Answer:
- The human digestive system is a series of organs that converts food into essential nutrients that are absorbed into the body.
- The digestive organs also move waste material out of the body.
- The enzymes in saliva help break down foods, and the lubrication function of saliva makes it easier for food to be swallowed.
- The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine (or colon), rectum, and anus.
- There are four steps in the digestion process: ingestion, the mechanical and chemical breakdown of food, nutrient absorption, and elimination of indigestible food.
