4 QUADRANTS OF ABDOMEN

Right upper quadrant

Following organs are present here :

The gall bladder, liver, colon (hepatic flexure), duodenum, and the upper part of the pancreas. Pain and tenderness in this area can be caused by conditions such as cholecystitis, hepatitis, and also the beginnings of a peptic ulcer.

Right lower quadrant

Following organs are present here :

Female reproductive organs (right fallopian tube and ovary), right ureterpenus, colon (upper portion), and the appendix. Patient with appendicitis, will experience the pain and tenderness localised to the right lower quadrant.

Left upper quadrant

Various parts of the colon are present here :

The bottom portion and splenic flexure, as well as the adrenal gland and also the kidney (left portion), spleen, stomach, pancreas and also a part of the liver (left portion) are present here.

Left lower quadrant

Found beneath the umbilicus plane, the left fallopian tube and ovary, and also the left uterine tube in women are present here. In both sexes we’ll find the sigmoid and bottom section of the colon. Pain from the left lower quadrant can be a sign of a number of conditions, including colitis, ureteral colic, or diverticulitis. Pelvic inflammation (such as is found with pelvic inflammatory disease) and ovarian cysts can also cause pain in this area, and even tumours associated with cancers, including colon and ovarian cancer.
