Which organ directly after the pharynx in the GI tract order?

Explanation:
The flow of digestion after swallowing goes from mouth to pharynx and then to the esophagus. The pharynx directs the swallowed material into the esophagus through the upper esophageal sphincter, and the esophagus uses muscle contractions (peristalsis) to move the bolus down to the stomach. The mouth comes before the pharynx, not after, and the rectum is far downstream after the whole digestive tract, with the stomach lying after the esophagus. So the organ directly after the pharynx is the esophagus.
