The organs of the accessory digestive system have the principal role of synthesizing and secreting digestive enzymes to further break down food into nutrients. From here it performs a number of turns as it passes through the temporal bone closely related to the inner ear and middle ear, giving off a number of branches, before exiting the skull via the stylomastoid foramen. In the portal venous system, the nutrient-rich blood from the digestive tract is drained by the hepatic portal vein into the liver to be filtered and detoxified.
