Question

food exits the stomach by passing through the:
a cardiac sphincter.
b lower esophageal sphincter.
c pyloric sphincter.
d hepatic sphincter.

Explanation:

• The cardiac sphincter (also known as the lower esophageal sphincter) is at the junction of the esophagus and stomach and prevents back - flow from the stomach to the esophagus, not for food exiting the stomach.
• The pyloric sphincter is located at the lower part of the stomach (pylorus) and controls the passage of partially digested food (chyme) from the stomach into the small intestine.
• The hepatic sphincter (sphincter of Oddi) is related to the flow of bile and pancreatic juice, not the exit of food from the stomach.

Answer:

C. pyloric sphincter.
