Food moves through the esophagus to the:
Stomach
Cecum
Common bile duct
Duodenum
The Correct Answer is A
A. Stomach: The esophagus carries food from the pharynx and empties it into the stomach via the lower esophageal sphincter.
B. Cecum: The cecum is part of the large intestine and is much further along in the digestive tract.
C. Common bile duct: This duct transports bile, not food. It is not directly connected to the esophagus.
D. Duodenum: The duodenum is the first part of the small intestine, which comes after the stomach, not directly after the esophagus.
