Digestive System Parts and Functions

Mouth:
The mouth breaks down carbohydrates chemically by producing saliva which slimes the food so it can slide down the esophagus easily; the mouth also physically digests food making it into smaller bits by chewing food.

Esophagus:
The esophagus is a muscular tube that squeezes the food down to the stomach.

Stomach:
The stomach stores food and mixes food which is mechanical digestion and that breaks down food further; the stomach produces an acid which helps breaking down protein and makes it easier for pepsin to break. Pepsin is an enzyme produced in the stomach which breaks down proteins.

Small intestine:
In the small intestine fats (lipids), carbohydrates and proteins are all finished getting digested. All these are absorbed into your blood for your body.

Pancreas:
The pancreas makes all the important enzymes for the small intestine to digest fats, carbohydrates and proteins. Lipase is an enzyme which digests fats, amylase is the enzyme which digests carbohydrates and pepsin is the enzyme which digests proteins. The pancreas also makes insulin in order for your body cells to suck up sugar (glucose).

Liver:
The liver makes bile which is stored in your gallbladder and sent to your small intestine to help break down fat. The liver filters blood from the small intestine and it also stores sugar so it can be released.

Large intestine:
The large intestine absorbs water it also stores undigested waste until it is expelled out of the anus.
