The digestive system is a network of organs that help you digest and absorb nutrition from your food. The system includes two tracts: gastrointestinal and biliary tract. 

​

Organs in the Gastrointestinal Tract: 

• ​mouth - initiates digestion through saliva, which breaks down food as you chew. The tongue then moves the food to the throat for swallowing.

• esophagus - transports food from the mouth to the stomach

• stomach - mixes food with digestive acids and enzymes, breaking it down into a more digestible form.

• small intestine  - Breaks down food using enzymes from the pancreas and bile from the liver. Food changes from semi-solid to liquid.

• large intestine - Processes waste by removing water, forming stool, and storing it until it's ready to be excreted.

• anus - Allows for the controlled release of stool

​

Organs in the Biliary Tract: 

• ​liver - Processes nutrients absorbed from the small intestine and produces bile to help digest fats.

• gallbladder - Stores and concentrates bile from the liver, then releases it into the small intestine to aid in fat digestion.

• pancreas - Produces digestive enzymes that break down proteins, fats, and carbohydrates in the small intestine. It also makes insulin, which regulates blood sugar levels by helping to metabolize sugar.
