Visceral peritoneum
Large organ in the abdomen that secretes bile and is active in the formation of certain blood proteins and in the metabolism of carbohydrates, fats, and proteins
Liver
Small, pear-shaped muscular sac under the right lobe of the liver; where bile secreted by the liver is stored until needed by the body for digestion
Gallbladder
Contains juices that have enzymes that help digest food in the small intestine as well as hormone production like insulin
Pancreas
Organ that is located in the upper-left part of the abdomen, not far from the stomach, that produces lymphocytes, which are important elements in the immune system

Ileum
Short section of the small intestine that takes in semi-digested food from the stomach and continues the digestion process; also uses bile from the gallbladder, liver, and pancreas to help digest food
Duodenum
Middle section of the small intestine that carries food through rapidly, with wave-like muscle contractions, towards the ileum
Jejunum
Last section and longest part of the small intestine where most of the nutrients from your food are absorbed before emptying into the large intestine (this is where it joins)
Ileum
The muscular portion of the intestinal wall contains an external band of longitudinal muscle the forms into three thickened bands
One positioned anteriorly and two positioned posteriorly
