Question

After swallowing, in which order does food pass through the regions of the GI tract? ​

Quizplus · Accepted Answer

After swallowing, food passes through the esophagus into the stomach, then into the duodenum (first part of the small intestine), followed by the jejunum (second part of the small intestine), then the ileum (third part of the small intestine), and finally into the colon (large intestine). The rectum is where feces are stored before elimination, and does not come into play with the order of food passing through the GI tract. Option C correctly lists the order of the regions through which food passes in the GI tract.
