The inter-abdominal cavity contains the following organs:

Step 6:  Add the spleen.
Step 7:  Add the liver.
Step 8:  Add the gallbladder. In order to see the gallbladder, you will have to rotate the cadaver so you can see under the liver.
Step 9:  Add the stomach.

These organs are inter-peritoneal and are supplied by the celiac trunk which is a branch off the abdominal aorta.

The stomach joins the duodenum which is retro-peritoneal through an opening in the peritoneal covering.

Step 10:  Add the duodenojejunal flexure. The duodenum returns to the inter-peritoneal space at the jucnction of the duodenum with the jejunum. This point is known as the duodenojejunal flexure.
Step 11:  Add the jejunum. Our digestive tract flows from the mouth to the esophagus trhough the duodenum to the jejunum.
Step 12:  The jejunum connects to the ileum.

The duodenum, jejunum and the ileum are considered the small bowel. This is where most of our nutrients are digested and absorbed.
