Which organ is included in the alimentary canal (GI tract)?

Explanation:
The main idea here is recognizing which organ is part of the digestive tube through which food travels. The mouth is the entry point of the alimentary canal, where chewing and saliva begin breaking down food so it can move on through the rest of the digestive system. The heart belongs to the circulatory system, pumping blood. The liver, while essential for digestion by producing bile, is an accessory organ outside the actual canal. The lungs are part of the respiratory system and have no role in digestion. So, the mouth is included in the alimentary canal.
