Explanation:
The alimentary canal, which is also called the gastrointestinal (GI) tract or gut, is the entire length of tube that winds through the body from the mouth to the anus and digests, breaks down and absorbs food through its lining into the blood
Organs within the alimentary canal include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine
The alimentary canal is considered outside of the body because it is open to the external environment at each end (mouth, anus)
