What is peritoneum?
Parietal vs Visceral peritoneum:
What is the function of the peritoneal cavity? (2)
▪Lubricates digestive organs
▪Contains leukocytes & antibodies
What are peritoneal organs? (3)
What are retroperitoneal organs? (3)
▪ Intraperitoneal organs:
Visceral peritoneum
▪ Retroperitoneal organs:
▪ Retroperitoneal organs – parietal peritoneum
(anterior surface only
▪ Primary retroperitoneal –
▪ Secondary retroperitoneaI -
▪ Primary retroperitoneal – develop outside
▪ Secondary retroperitoneaIl – move outside during
developmen
▪ Retroperitoneal viscera:
SADPUCKER
Visceral peritoneum innervation: (3)
▪ Autonomic supply (same as the viscera)
▪ Pain is referred to equivalent :hard to used clinically dermatomes (poorly localised) —> hard to be used clinically
▪ Sensation limited to stretch and chemical irritation (rupture , enzymes leak out in peritoneum)
Autonomic supply of visceral peritoneum: (2)
Parietal peritoneum innervation: (2)
▪ Mesentery – double layer of peritoneum that provides: (3)
▪Small intestine→ the mesentery…
Connect/SI to posterior abdomen wall.
▪ Colon → _______
(transverse, sigmoid etc. )
mesocolon
▪ Appendix → ________
mesoappendix
Omenta: (2)
▪ Greater omentum
▪ Lesser omentum
What is the greater omentum?
Connects stomach to transverse colon
What is the lesser omentum? (3)
What are the contents of the omenta? (3)
Portal triad
▪ Common bile duct
▪ Proper hepatic artery
▪ Hepatic portal vein
What is the function of peritoneum?
Connects organs to each other or to posterior abdominal wall.
What are the peritoneal ligaments of the liver? (5)
What are the peritoneal ligaments of the stomach? (3)
What are the peritoneal ligaments of the colon?
What are the peritoneal ligaments of the spleen?
What are the compartments of the greater sac? (2)
What is the lesser sac?
What are the other peritoneal cavity subdivisions? (2)
▪ Peritoneal gutters
▪ Peritoneal recesses
Peritoneal Cavity Subdivision
Clinical POV: (2)
▪Pathways for fluid
accumulation
▪Infection and inflammation spread
What is the transverse mesocolon?
Superior recess of mental bursa
What does the greater peritoneal sac subdivide?
What is the greater peritoneal sac connected by?
Lesser peritoneal sac —> omental ____.
bursa
What is the lesser peritoneal sac? (4)
▪ Posterior to stomach and lesser omentum
▪ Superior recess extends behind liver
▪ Inferior recess between layers of the greater omentum
▪ Permits free movement of stomach
What is the lesser peritoneal sac? (4)
▪ Posterior to stomach and lesser omentum
▪ Superior recess extends behind liver
▪ Inferior recess between layers of the greater omentum
▪ Permits free movement of stomach
What does the lesser peritoneal sac communicate with?
What are peritoneal recesses?
DISCH
▪Pouches of peritoneum formed by peritoneal folds
What are the types of peritoneal recesses? (5)

▪ Caecal recesses
▪ Intersigmoid recess
▪ Subphrenic recesses
▪ Hepatorenal recess
What are the ▪ Caecal recesses? (3) SIR
▪Superior ileocaecal
▪Inferior ileocaecal
▪ Retrocaecal
