How it works

An abdomen anatomy quiz on one drawing seen from the front. Name the organs first, then label the nine regions of the abdominal cavity.

Read the full guide

The organs in place

The diaphragm roofs the abdomen. Under it the liver lies on the body's right and the stomach to its left, with the spleen beyond. The large intestine makes a frame: cecum and appendix, then the ascending, transverse, descending and sigmoid colon. The small intestine fills the frame, and the bladder sits low in the pelvis.

The nine regions

Two upright and two level lines make nine regions. The middle column is epigastric, umbilical and hypogastric. On each side are the hypochondriac, lumbar and iliac regions. Left and right are the body's own, so the right regions are on the left of the drawing.

  • The greater omentum is cut short here; in life it hangs over the intestines like an apron.
  • The quiz accepts pubic for hypogastric, flank for lumbar and inguinal for iliac.

Questions and answers

What are the nine regions of the abdomen?

Top row: right hypochondriac, epigastric and left hypochondriac. Middle row: right lumbar, umbilical and left lumbar. Bottom row: right iliac, hypogastric and left iliac.

How do I label the various abdominal structures on a front view?

Start with the three big ones: the liver on the body's right, the stomach on its left and the coils of small intestine below. Then follow the large intestine round its frame, from the cecum to the sigmoid colon.

What are the four quadrants of the abdomen?

Right upper, left upper, right lower and left lower, divided at the navel. They are a simpler map than the nine regions. This page asks the nine regions only.

Why is the right hypochondriac region on the left of the drawing?

Left and right are named from the body's own point of view. The person in the drawing faces you, so their right side is on your left.
