What major organ is located in the RUQ?

The liver is the major organ located in the right upper quadrant (RUQ) of the abdomen. It plays a critical role in various bodily functions, including detoxification, metabolism of nutrients, and production of bile, which aids in digestion. Its size and position in the body make it easily identifiable in the RUQ, distinctly separated from other organs situated in different abdominal quadrants.

The spleen, while important, is located in the left upper quadrant (LUQ). The appendix is located in the right lower quadrant (RLQ), and the rectum is situated in the pelvic region, not specifically in any of the four abdominal quadrants. Understanding these anatomical locations is crucial for various medical and emergency-related assessments, emphasizing the liver's significance in the RUQ.
