Sutures and Wound Repair/ General Surgery (ABSA) Practice Test

What is the correct sequence of the digestive structures starting from the esophagus?

1. Esophagus, Pyloric sphincter, Duodenum, Jejunum

2. Esophagus, Cardiac sphincter, Fundus, Duodenum

3. Esophagus, Diaphragm, Cardiac sphincter, Fundus, Pyloric sphincter

4. Esophagus, Fundus, Diaphragm, Jejunum, Ampulla of Vater

The correct answer is: Esophagus, Diaphragm, Cardiac sphincter, Fundus, Pyloric sphincter

The correct sequence of the digestive structures starting from the esophagus is accurately represented by the choice provided. This option includes the esophagus, which is the tube that connects the throat to the stomach. Next in the sequence is the diaphragm, which is the muscle that separates the chest from the abdominal cavity and plays a role in the movement of the esophagus into the stomach. Following the diaphragm, the cardiac sphincter (also known as the lower esophageal sphincter) controls the passage of food from the esophagus into the stomach and prevents the backflow of stomach contents. After that, the fundus is the upper part of the stomach, which serves as a temporary storage area for food and can accommodate gas from the stomach contents. The gastric emptying then transitions through the pyloric sphincter, leading to the duodenum, which is the first part of the small intestine. However, this pathway emphasizes the structures leading from the esophagus to the stomach rather than through the duodenum. Thus, the sequence encapsulates the initial steps of digestion, highlighting significant structures in their proper order within the digestive system. The correct choice emphasizes the passage from the esophagus through these structures, establishing a clear pathway of how ingested materials move
