Which structures are commonly found in the left lower quadrant?

• A. Bladder and uterus
• B. Right kidney and appendix
• C. About half of small intestines and colon, left ovary and fallopian tube, left ureter
• D. Liver and gallbladder

Answer: (C)

In the left lower quadrant you expect to find structures on the left side of the abdomen and in the pelvic region. Specifically, portions of the small intestine and the left side of the colon (including the descending and part of the sigmoid colon) are located there, along with pelvic structures on the left such as the left ovary and left fallopian tube. The left ureter, which runs from the kidney down to the bladder, also passes through this area. By contrast, the liver and gallbladder sit in the right upper quadrant, the appendix is in the right lower quadrant, and the bladder and uterus are in the pelvis (with the uterus generally midline). That combination of left-sided digestive, urinary, and pelvic organs is what characterizes the left lower quadrant.
