RADR 2331 Chapter 12 Q&A 150+ Questions – GI System Liver Gallbladder Stomach Duodenum

This document provides a comprehensive collection of over 150 exam-style questions with verified answers for RADR 2331 Chapter 12, focusing on the gastrointestinal (GI) system and accessory digestive organs. It is designed to help students master both anatomical structures and radiographic applications related to digestion and abdominal imaging. The material begins with key concepts of the liver and biliary system, including liver function, bile production, and bile flow pathways (page 1–2). It also covers gallbladder anatomy (fundus, body, neck) and physiology, including contraction mechanisms (CCK) and positioning considerations for imaging (e.g., PA vs supine positions) . The document further explores digestive terminology and imaging procedures such as cholecystography, esophagography, and upper GI studies (pages 3–4). A major portion focuses on the anatomy and function of the alimentary canal, including the esophagus, stomach, and duodenum. It includes detailed coverage of peristalsis, swallowing (deglutition), stomach regions (fundus, body, pylorus), curvatures, rugae, and duodenal segments (pages 5–8). The document also integrates positioning and imaging techniques, such as RAO positioning for esophagrams and barium distribution in different patient positions (pages 5–7). Additionally, the content includes clinical correlations such as gallstones (cholelithiasis), biliary stenosis, diverticula, bezoars, and body habitus variations affecting GI anatomy and imaging (pages 10–13). It also covers absorption processes (carbohydrates, proteins, lipids), accessory organs, and radiographic positioning principles, making it highly relevant for both exams and clinical practice. The material aligns closely with standard textbooks such as Bontrager’s Textbook of Radiographic Positioning and Related Anatomy and Introduction to Radiologic and Imaging Sciences and Patient Care by Arlene M. Adler and Richard R. Carlton. It is particularly suitable for students enrolled in Radiologic Technology (RADR2331), Medical Imaging, and Radiography programs. This document is ideal for radiography students, medical imaging students, nursing students, and allied health learners preparing for exams, lab assessments, or registry-level examinations such as ARRT.
