When the food enters in our body and moves out through the anus, the process of digestion occurs, the pathway through which food enters our body is called the alimentary canal. It starts from the mouth and ends in the anus and has a tube-like structure. The alimentary canal plays a major role in human digestion and is also called the digestive tract.
The length of the alimentary canal which starts from the esophagus and ends in the anus is about 30 feet long.
