An accessory digestive organ is an organ that helps in digestion but is not a part of the digestive tract. Tongue, salivary glands, pancreas, liver, and gallbladder are accessory digestive organs. These are technically not a part of the alimentary canal but are essential for digestion. Stomach, on the other hand, is an integral part of the digestive tract.
