ingestion, secretion, digestion, mixing and propulsion, absorption, and defacation [ISDM(p)AD)
What are the 4 layers of the GI tract?
Mucosa, submucosa, muscularis, adventitia/serosa

What are the organs of the digestive system?
GI tract + accessory organs
Describe the 5 folds of the peritoneum and location.
Greater omentum: greater curvature of the stomach originates from the posterior wall
Lesser omentum: lesser curvature of the stomach originates from the posterior wall
Mesentery: parietal peritoneum of the intestines originates from the posterior wall
mesocolon: mesentery of the colon and for the large intestines originates from the posterior wall
falciform ligament: runs through the liver connecting the anterior abdominal wall to the liver originates from the anterior wall
