Duodenum Jejunum Ileum Appendix Colon Sigmoid Rectum

Liver Lobes

The four lobes of the liver: caudate, quadrate, left and right, bring to mind the newspaper headline of the wheelchair bound fellow who left a party right after his ugly girlfriend departed: "QUAD LEFT RIGHT after COW-DATE"

Pertoneum Facts

The idea is to relate key letters of related parts...

stOMach and OMentum (which lays over the stomach)
The bacterium e. coLI is found in the Large Intestine
The OMentum covers the stOMach
The Lesser OMentum holds the Liver and stOMach
The Mesentery holds the sMall intestine
The mesoCOLON attaches the large intestine (COLON) to the posterior abdominal wall.
The periTONEa, which prevents the intestines from kinking, TONES the GI tract.

Sphincters of the Ailmentary Canal

APE OIL initials the five of them...

A P E O I L

Anal Pyloric (Lower) Esophageal Oddi Ileocecum iLeocecum

Stomach Parts

"The CAR is FUN 'til the BODY PILES" relates the four parts of the stomach: Cardiac, Fundus, Body, Pylorus. The pylorus is where the food piles waiting for the sphincter to open.
