In general, the digestive system is controlled by both nerves and hormones. The nerves that control digestion are in the submucosa layer of the tissue and in between the muscle layers of the walls of the organ.
The liver, pancreas and gall bladder are called accessory organs. This means they work with the GI tract to break down food. The liver is the largest gland in the body, weighing about 1.5 kg (3.3 lb) in an adult. The liver has many roles in the digestive system. For example, it: produces a green fluid called bile, which breaks down fats. removes wastes and toxins from the body. breaks down nutrients and stores some vitamins and minerals.
