Flexi Says: The accessory organs are the liver, gall bladder, and pancreas. The liver performs gluconeogenesis, glycogenolysis, and glycogenesis in carbohydrate metabolism. The liver is one of the most important organs in the body when it comes to blood filtering and detoxification. The toxins are usually excreted in bile or urine. The liver also performs several roles in lipid metabolism including cholesterol synthesis and the production of triglycerides (fats). The gallbladder stores bile made in the liver and squeezes the bile through tubes called bile ducts into your small intestine. Bile helps break down fats. The pancreas is a gland below the stomach. It produces digestive substances that are carried by a duct to the small intestine. Pancreatic lipase, produced in the pancreas. It is used to break apart fats.
