contains majority of liver, gallbladder, small portion of pancreas, righ tkidney, small intestines, and colon
right lower quadrand (RLQ)
contains small intestines and colon, right ovary and fallopian tube, appendix, and right ureter
left upper quadrant (LUQ)
contains small portion of liver, spleen, stomach, majority of pancreas, left kidney, small intestines, and colon
