Which organ is primarily located in the Right Upper Quadrant?

Stomach Liver Spleen Appendix

Correct Answer:

Liver

Explanation:

Understanding how abdominal organs are distributed in the four quadrants helps identify which organ sits in the right upper quadrant. The liver is primarily located under the right side of the diaphragm, occupying most of the right upper quadrant. It’s the body’s largest internal organ, and while its left lobe reaches toward the left, the bulk sits on the right. The gallbladder is attached to its underside in that same region. In contrast, the stomach is mainly in the left upper quadrant and the epigastric area, the spleen is in the left upper quadrant, and the appendix is in the right lower quadrant. So, among these options, the organ most associated with the right upper quadrant is the liver.
