Digestive System
The Digestive System (pronunciation: /dɪˈdʒɛstɪv ˈsɪstəm/) is a group of organs working together to convert food into energy and basic nutrients to feed the entire body.
Etymology
The term "digestive" is derived from the Latin word "digestivus", which means 'that which serves to separate or dissolve'.
Anatomy of the Digestive System
The digestive system is made up of the gastrointestinal tract (GI), liver, pancreas, and gallbladder.
Gastrointestinal Tract
The gastrointestinal tract (GI tract) is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
Liver
The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine.
Pancreas
The pancreas has two main functions within the digestive system. It produces important enzymes and hormones that help break down foods.
Gallbladder
The gallbladder stores and concentrates bile, a substance needed to help digest fats.
Function of the Digestive System
The digestive system breaks down food into nutrients, which the body uses for energy, growth, and cell repair. This process is also known as digestion.
