Sad pucker

It's not alway easy for beginning students to remember which organs are peritoneal and which are retroperitoneal.

One easy way to remember which abdominopelvic organs are retroperitoneal is to use a mnemonic such as SAD PUCKER:

• S = Suprarenal (adrenal) glands
• A = Aorta/Inferior Vena Cava
• D = Duodenum (second and third segments)
  
• P = Pancreas
• U = Ureters
• C = Colon (ascending and descending only)
• K = Kidneys
• E = Esophagus
• R = Rectum

Or instead, Ursula Uses Kids to Deliver All Lemon Pies except Sue’s Tasty Crust

• Ureters
• Urinary bladder
• Kidneys
• Duodenum
• Adrenal glands
• Large intestine
• Pancreas
• exept (not retroperitoneal) Sigmoid and Transverse Colon
