Accessory digestive organs are those that help in digestion, but are not a part of the digestive tract. The accessory digestive organs are the tongue, salivary glands, pancreas, liver, and gall bladder. These are technically not a part of the alimentary canal but release their secretion into the alimentary canal which is essential for digestion.
