Explanation:
The gastriointestinal tract refers to the entire digestive system, starting at the mouth, and ending at the anus. After food enters through the mouth, it travels through the esophagus, into the stomach. After that, it moves into the duodenum, then the jejunum, and finally the ilium (collectively referred to as the small intestine). Finally it moves into the cecum, then to the colon, and finally the rectum (collectively referred to as the large intestine), where it exits out the body through the anus.
The length of this process varies due to stress, metabolism, and even sleep.
