Question

multiple choice question
the gi tract begins with the ________.
stomach
pharynx
nose
mouth

Explanation:

The gastrointestinal (GI) tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The mouth is the starting point where food enters the digestive system. The stomach is further along in the digestive process (after the mouth, pharynx, and esophagus). The pharynx is part of the upper digestive and respiratory systems but is not the very beginning. The nose is part of the respiratory system and not part of the GI tract.

Answer:

mouth
