Which organs are located in the right lower quadrant?

• A. Colon, Small Intestine, Ureter, and Appendix
• B. Liver, Colon, Ureter, and Appendix
• C. Stomach, Appendix, and Ileum
• D. Spleen, Cecum, and Ureter

Answer: (A)

In the right lower quadrant you primarily find parts of the digestive and urinary systems that run along the right side: the colon (specifically the ascending colon and the cecum area), the terminal portion of the small intestine (ileum), and the right ureter as it descends to the bladder. The appendix sits in this region as well. So, a listing that includes colon, small intestine, ureter, and appendix matches the typical anatomy of the RLQ.

The liver sits in the right upper quadrant, the stomach is mainly in the left upper quadrant, and the spleen is in the left upper quadrant, so options including those organs don’t describe the RLQ accurately.
