The digestive system is a group of organs that break down food (physically and chemically) so that it can be used by the body cells. The organs of the digestive system can be divided into two: Gastrointestinal (GI) tract or alimentary canal  Accessory digestive organs These organs are called “ accessory ” because food does not pass through them, yet digestion would be impossible without them The accessory digestive organs include the teeth , tongue , salivary glands , liver , gallbladder , and pancreas .  Teeth: helps in physical breakdown of food Tongue: helps in chewing and swallowing food Other accessory digestive organs: produce or store secretions that help   in the chemical breakdown of food
