Which structure is listed under LLQ?

• A. Gallbladder
• B. Appendix
• C. Spleen
• D. Right ureter

Answer: (B)

The left lower quadrant contains structures on the left side of the abdomen, such as the sigmoid colon and descending colon, the left ureter, and the left ovary (in females) or left testicular structures (in males), as well as portions of the left kidney. The gallbladder is in the right upper quadrant, the appendix is in the right lower quadrant, the spleen is in the left upper quadrant, and the right ureter runs on the right side. Because of this, none of the listed structures are typically described as located in the left lower quadrant; a left-sided structure you’d expect there would be the sigmoid colon or the left ureter. If a question seems to point to LLQ, focus on these left-sided structures and consider conditions like diverticulitis or left‑sided renal/ovarian pathology.
