The left lower quadrant contains which structures?

• A. Small and large intestines and the left ureter
• B. Stomach and spleen
• C. Liver and gallbladder
• D. Appendix

Answer: (A)

In the left lower quadrant, the organs you’d expect are parts of the digestive tract and a urinary structure. Specifically, loops of the small intestine and portions of the large intestine—the descending and sigmoid colon—sit in this area, along with the left ureter as it travels down to the bladder. That combination matches the option describing small and large intestines and the left ureter, making it the correct choice.

Stomach and spleen are higher up in the left upper quadrant, while the liver and gallbladder are primarily in the right upper quadrant (with some limited extension toward the left). The appendix is located in the lower right quadrant.
