The human abdomen is divided into four quadrants to help locate and diagnose pain or other medical issues. These quadrants are the right upper quadrant, left upper quadrant, right lower quadrant, and left lower quadrant. Each quadrant contains specific organs, making it easier for healthcare professionals to identify potential problems. The right upper quadrant includes the liver and gallbladder, while the left upper quadrant contains the stomach and spleen. The right lower quadrant houses the appendix, and the left lower quadrant contains parts of the intestines. Understanding these quadrants aids in effective communication during medical assessments.
