In the GI tract order, which organ immediately follows the mouth?

Explanation:
Food entering the mouth next moves into the pharynx. The pharynx is a muscular passageway that serves as the first shared route for both digestion and respiration, and it initiates swallowing to push the bolus toward the esophagus. From there, peristaltic waves carry the contents down to the stomach. The stomach comes after the esophagus, and the rectum is far downstream in the digestive tract. So the organ immediately following the mouth is the pharynx.
