Study Notes

Digestive System Organs & Functions

Salivary Glands: Produce salivary amylase, a carbohydrate enzyme.
Sphincters: Rings of muscle, often closed, regulating the flow of food.
Oesophagus: The food pipe, transferring food from mouth to stomach.
Stomach: Churns food, producing protease enzyme and hydrochloric acid (for killing bacteria and proper pH).
Liver: Produces bile, which emulsifies fats, neutralising stomach acid.
Gall Bladder: Stores bile before releasing it into the small intestine.
Pancreas: Produces all three enzymes: protease, carbohydrase, and lipase.
Small Intestine: Produces protease, carbohydrase, and lipase; absorbs food into the blood. Inner surface has villi for increased absorption area.
Large Intestine: Absorbs excess water from the food.
Rectum: Stores faeces before elimination.
