The accessory organs of digestion include the salivary glands, pancreas, liver, and gallbladder. As stated earlier, during the digestive process, the accessory organs produce secretions that assist the organs of the alimentary canal.
saliva is 98% water, but it contains many important substances, including electrolytes, mucus, antibacterial compounds and various enzymes.
The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine.
The gallbladder holds bile produced in the liver until it is needed for digesting fatty foods in the duodenum of the small intestine.
The hormones insulin and glucagon are also made in the pancreas and help to regulate the blood sugar level.
