# Section 1: Anatomy & Physiology of the GI System (20 Questions)
**Question 1.**
The primary function of the gastrointestinal system is:
A) Oxygenation of blood
B) Digestion and absorption of nutrients
C) Regulation of body temperature
D) Production of hormones
**Answer:** B) Digestion and absorption of nutrients
**Rationale:** The GI system breaks down food into absorbable
nutrients and eliminates waste. Oxygenation is respiratory; temperature
regulation is integumentary/neurologic.

**Question 2.**
The esophagus is located directly anterior to which structure?
A) Trachea
B) Aorta
C) Vertebral column
D) Heart
,3|Page
**Answer:** A) Trachea
**Rationale:** The esophagus lies posterior to the trachea in the
mediastinum. This anatomical relationship is important for
understanding aspiration and esophageal disorders.
---
**Question 3.**
The lower esophageal sphincter (LES) is also known as the:
A) Pyloric sphincter
B) Cardiac sphincter
C) Ileocecal valve
D) Sphincter of Oddi
**Answer:** B) Cardiac sphincter
**Rationale:** The LES (cardiac sphincter) prevents reflux of gastric
contents into the esophagus. The pyloric sphincter controls gastric
emptying; the ileocecal valve connects small and large intestine.
---
**Question 4.**
, 4|Page
The stomach is divided into which four anatomical regions?
A) Fundus, body, antrum, pylorus
B) Duodenum, jejunum, ileum, cecum
C) Hepatic, cystic, pancreatic, gastric
D) Cardia, fundus, body, pylorus
**Answer:** D) Cardia, fundus, body, pylorus
**Rationale:** The four regions of the stomach are the cardia (near
esophagus), fundus (upper curved portion), body (main central region),
and pylorus (antrum and pyloric canal).
---
**Question 5.**
Parietal cells of the stomach secrete:
A) Pepsinogen
B) Hydrochloric acid (HCl) and intrinsic factor
C) Gastrin
D) Mucus
**Answer:** B) Hydrochloric acid (HCl) and intrinsic factor
