What are the two layers of the peritoneum?
Parietal and visceral peritoneum
What makes up the portal triad?
Portal vein, hepatic artery, and bile duct
What are the two divisions of the peritoneal cavity?
Greater sac and an omental bursa
Boundaries of the omental foramen
- Hepatoduodenal ligament, hepatic artery, and bile duct
- IVC and right crus of diaphragm
- Liver
- First part of the duodenum
What are the three branches of the abdominal aorta?
Celiac trunk, superior and inferior mesenteric arteries
What is the hepatic portal vein formed by?
Union of the superior mesenteric, inferior mesenteric, and splenic veins
Arterial supply of the esophagus
Esophageal branches of the left gastric artery and the inferior phrenic nerve
Venous drainage of esophagus
Left gastric vein and the esophageal vein
Lymphatic drainage of the esophagus
Left gastric lymph node and celiac lymph node
Innervation of the esophagus
Vagal trunks, thoracic sympathetic trunks (via greater splanchnic nerves) and the periarterial plexus
Arterial supply of the stomach
Right and left gastric arteries, right and left gastro-omental arteries, and short and posterior splenic arteries
Venous drainage of the stomach
Left and right gastric veins, short gastric veins, and right and left gastro-omental veins
Innervation of the stomach
Parasympathetic: anterior and posterior vagal trunk
Sympathetic: Celiac plexus

Fundus, body, and neck
What is the relation of the right suprarenal gland?
Lies anterior to the diaphragm and makes contact with the IVC anteromedially and the liver anterolaterally
What is the relation of the left suprarenal gland?
Related to the spleen, stomach, pancreas, and the left crus of the diaphragm
What are the three sources of arteries to the ureters?
Renal artery, testicular or ovarian arteries, and abdominal aorta
Autonomic nerves of the abdomen
Consist of several different splanchnic nerves and one cranial nerve (CN X) that deliver presynaptic sympathetic and parasympathetic fibers to the abdominal aortic plexus and its associated sympathetic ganglia
Round ligament of the liver
Sits inferior to the falciform ligament
Where does the greater omentum originate?
Greater curvature of the stomach
Where does the lesser omentum originate?
Lesser curvature of the stomach
What are four unique structures of the large intestine?
Teniae coli, haustra, omental appendices, and caliber
