Digestive System Functions Image
The digestive system breaks down the foods we eat into energy our bodies can use. Bacteria in the gastrointestinal tract (also called gut flora or microbiome) also help with digestion, along with parts of the nervous and circulatory systems. What Are the Four Main Functions of the Digestive System?
Your digestive system is made up of the gastrointestinal (GI) tract and your liver, pancreas and gallbladder. The GI tract is a series of hollow organs that are connected to each other from your mouth to your anus.
