Abdominal Cavity and Peritoneum Flashcards
What is an intraperitoneal organ
suspended by mesenteries and surround by peritoneum
What is carried in mesenteries
vessels, nerves, and lymphatics
What is retroperitoneal
situated or occurring behind the peritoneum
What are the two layers of peritoneum
visceral and parietal
What is the falciform ligament
ventral mesentery between liver and abdominal wall
What is the greater omentum
apron-like fold of visceral peritoneum that hangs down from the stomach
What is the greater sac
anterior portion of the peritoneal cavity, potential space
What is lesser sac
space situated behind the liver, pancreas, and stomach
potential space
What does the mesentery proper attach
small intestine to posterior wall
How will the greater omentum respond to infection
move within the abdomen wall to block off an infection
How does the peritoneal cavity in men and women differ
men: closed
women: opening due to uterine tubes into the periotneum
What viscera are contained within the peritoneal cavity
None
What is contained within the fluid in the peritoneal cavity
potential space, contains leukocytes, antibodies, fluid
How is the peritoneum relevant clinically
peritoneal cavity
ventriculoperitoneal shunt
infection and malignancies
What is ventriculoperitoneal shunt
too much CSF can be drained to peritoneal cavity
What are the structures formed by the peritoneum
mesentery
ligament
omentum
What is the transverse mesocolon
mesentery of the transverse colon
What is the gastrocolic ligament
portion of the greater omentum that attaches stomach to transverse colon
What are the hepatogastric and hepatoduodenal ligaments a part of
lesser omentum
What are the retroperitoneal organs
aorta IVC kidneys bladder ureter
What are the boundaries of the omental foramen
Anterior: portal v, hepatic a, bile duct inside the hepatoduodenal ligament
Posterior: IVC, right crus diaphragm
Superior: caudate lobe of liver
Inferior: first part of duodenum
What is the portal triad composed of
bile duct
hepatic artery
portal vein
Where is the portal triad found
hepatoduodenal ligament of lesser omentum
What is the innervation and vasculature of the parietal peritoneum
same as abdominal wall
What is the innervation and vasculature of the visceral peritoneum
same as viscera
How are the supracolic and infracolic compartments separated
transverse mesocolon
What organs are contained within the supracolic compartment
stomach
liver
spleen
What organs are contained within the infracolic compartment
small intestine
ascending and descendign colon
Where will fluid within the right paracolic gutter spread
around liver down to pelvic cavity
Where will fluid within the left paracolic gutter spread
spread inferiorly but limited superiorly
What limits the spread of fluid from the left paracolic compartment
phrenicocolic ligament
Where will fluid in the right infracolic spread
no where. limited to the right infracolic space, no outward channel
What are the two main spaces within the abdomen that fluid may collect
hepatorenal recess (morrison's pouch) rectovesical pouch/rectouterine
