Where the abdominal organs are
The abdomen runs from the diaphragm below the chest down to the pelvis. The liver and gallbladder sit in the upper right and the stomach and spleen in the upper left, the pancreas lies crosswise deep behind the stomach, and the kidneys sit at the back on either side of the spine. The small intestine fills the middle in coils, and the large intestine frames it.
Frequently asked questions
How are positions in the abdomen described?
Lines through the navel, one across and one down, divide it into four quadrants: upper right, upper left, lower right and lower left. The liver and gallbladder are in the upper right, the stomach and spleen in the upper left, the caecum and ascending colon in the lower right and the descending colon in the lower left.
What is the largest organ in the abdomen?
The liver. It sits in the upper right of the abdomen under the ribs and is the largest internal organ, with the gallbladder tucked beneath it.
Where in the abdomen are the kidneys?
Towards the back rather than the front, at waist height on either side of the spine. Their upper ends are sheltered by the lower ribs, and an adrenal gland sits on top of each.
