produces bile, which breaks down globules of fat into smaller droplets that can be more easily digested and absorbed
secretes substances that neutralize the chyme as well as enzymes that aid in the chemical digestion of carbohydrates, proteins, and fats
stores bile and releases it into the small intestine
gallbladder
liver
pancreas
