Aug 20, '12 by Ansumana. I can give you a quick run down of all organs in the quadrants and body parts as well. RUQ/right hypochondria: right axillary & right lung. Right lumbar region: liver, ascending intestine (part of large intestine), a little of the small intestine, and gallbladder. RLQ/ inguinal region: contains right kidney which is retroperitoneal to the body. (center of the body). HYPERgastric region: this contains the heart and part of the left lung.
The lower quadrants are a little less exciting that the upper quadrants, though they are still vitally important. In the right lower quadrant (RLQ) you find the cecum, appendix, portions of small intestine, right reproductive organs, and the right ureter. The cecum forms the beginning of the large intestine. In herbivores, the cecum is where bacteria break down cellulose from plants.
