  • Gallbladder
  • Right kidney
  • Part of the stomach
• Left Upper Quadrant (LUQ):
  • Spleen
  • Left kidney
  • Parts of the stomach
  • Pancreas
• Right Lower Quadrant (RLQ):
  • Appendix
  • Right reproductive organs
• Left Lower Quadrant (LLQ):
  • Left reproductive organs
• All quadrants contain parts of the large and small intestines.

Nine Abdominal Regions

• Hypochondriac (Right and Left): Located under ribs on upper abdomen sides.
  • Right: Liver, gallbladder, right kidney, intestines.
