What is the right upper quadrant?

The right upper quadrant (RUQ) is one of the four anatomical divisions of the abdomen, primarily located on the right side above the transverse plane that divides the body horizontally. It contains several vital organs, including the liver, gallbladder, right kidney, and parts of the pancreas and intestines. Clinically, the RUQ is significant for diagnosing conditions like gallbladder disease, liver disorders, and certain gastrointestinal issues. Pain or discomfort in this area can indicate various medical concerns, warranting further evaluation.
