The stomach is the primary organ that breaks down food as it enters the digestive system. This organ receives food from the esophagus and eventually directs the partially digested food into the small intestine. It also helps kill harmful bacteria.
Encyclopaedia Britannica explains that most of the water that a person drinks is absorbed in the intestines; however, many sources disagree about which part of the intestines is most responsible for water absorption.

The three main functions of the human digestive system are to break food down into chyme for the body's use, to secrete and absorb nutrients and bodily fluids into the gastrointestinal tract or the blood, and to store and eliminate waste. The digestive system has major parts and accessory parts.

Mechanical digestion aids chemical digestion by breaking food into smaller pieces with a greater surface area, as well as introducing enzymes to begin the process of chemical digestion. In humans, much of mechanical digestion takes place in the mouth through chewing, during which the teeth break up
The digestive and endocrine systems work together, mostly through the pancreas, to produce and disseminate digestive enzymes.

For a science project focusing on the digestive system, kids can make a model stomach and a model small intestine. They can also make a wide array of digestive components, but the stomach and small intestine are the easiest and most enjoyable for children.
