Describe the parts the accessory organ play in the digestion of food

See the explanation below.

Explanation:

Chemical digestion in the small intestine relies on the activities of three accessory digestive organs: the liver, pancreas, and gallbladder.

The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile. The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum.

The liver, pancreas, and gallbladder are considered accessory digestive organs, but their roles in the digestive system are vital.
