enzyme in the stomach that digests proteins
acid found in the stomach
where food is absorbed into the blood
structures that increases surface area inside the small intestine
contains enzymes from the pancreas that digest proteins, carbohydrates, lipids, and nucleic acids
where water is reabsorbed into the blood from the digestive system
bacteria found in the large intestine
makes enzymes that break down proteins, carbohydrates, lipids, and nucleic acids and then sends those enzymes to the small intestine
makes bicarbonate to neutralize acids in the small intestine
stores and concentrates bile
