529473854	What connects the parietal peritoneum to the visceral peritoneum?	Mesentery
529473855	Which peritoneum layer is innervated by general sensory fibers, causing pain?	Parietal peritoneum
529473856	Which peritoneum is supplied by blood vessels and lymph drainage of the viscera?	Visceral peritoneum
529473857	What are the intraperitoneal organs?	Stomach, 1st part of duodenum, liver, tail of pancreas, spleen, jejunum, ileum, transverse colon and sigmoid colon
529473858	What are the retroperitoneal organs?	(posterior to peritoneum) Urinary, circulatory (aorta/VC), esophagus, 2-4th parts of duodenum, pancreas, ascending colon, descending colon,
529473859	What is the term for organs that are covered with parietal peritoneum but not visceral peritoneum?	Secondarily retroperitoneal
529473860	Excess fluid in the peritoneal cavity, often the result of inflammation of the peritoneum	ascites
529473861	What is the name of the reflection of the peritoneum that is suspended from the greater curvature of the stomach?	greater omentum
529473862	What is the purpose of the greater omentum?	Provides pathways for neurovascular structures and can prevent the spread of infection
529473863	What happens to the greater omentum during development?	Fuses together to form single sheath
529473864	What is the purpose of the lesser omentum?	Pathways for neurovascular structures
529473865	What two ligaments make up the lesser omentum?	Hepatogastric and hepatoduodenal ligaments
529473866	What divides the greater sac into the supracolic and infracolic compartments?	Transverse colon
529473867	Where are the three recesses of the greater sac?	Subphrenic (between liver and diaphragm), Morison's pouch (below liver), Paracolic recesses on either side of colon
529473868	Where is the lesser sac (omental bursa)?	Behind the liver, lesser omentum, and stomach
529473869	Where is the omental foramen (epiploic foramen of Winslow)?	Behind hepatoduodenal ligament
529473870	What can accumulate in the omental bursa (lesser sac)?	Loop of intestine (hernia), fluid
529473871	What three things are found in the portal triad in the hepatoduodenal ligament?	Common bile duct, portal vein, proper hepatic artery
529473872	What is found posteriorly within the portal triad?	Portal vein
529473873	What suspends organs from body wall or connects organs to each other?	Mesentery
529473874	What is the location of the posterior body wall when parietal peritoneum reflects and forms the double layer?	Root of the mesentery
529473875	What does the root of the mesentery refer to?	Root of small intestine
529473876	Name the 2 peritoneal ligaments connecting the spleen.	Gastrolienal and lienorenal
529473877	Name the 2 peritoneal ligaments connecting the liver.	Falciform (liver to diaphragm and ab wall) and coronary (top, bare area of liver)
529473878	Name the 2 peritoneal ligaments that are embryological remnants.	Ligamentum teres hepatis and ligamentum venosum
529473879	About which vertebrae level is the celiac trunk? What does it supply?	T12; supplies the foregut (liver, stomach, spleen)
529473880	About which vertebrae level is the superior mesenteric artery? What does it supply?	L1; supplies the midgut (SI, ascending LI, transverse LI)
529473881	About which vertebrae level is the inferior mesenteric artery? What does it supply?	L3; supplies the hindgut (descending LI, rectum)
529473882	Branches of celiac trunk/axis	Common hepatic a., splenic a., left gastric a.
529473883	The celiac trunk splits to the common hepatic on the right side. What 3 things does the common hepatic then split into?	Proper hepatic (which splits again to L and R), right gastric a., gastroduodenal a.
529473884	The celiac trunk splits to the splenic artery on the left side. What two branches does this form?	Short gastric a., left gastroepiploic a.
529473885	What is the smallest branch of the celiac trunk and where does it run?	Left gastric artery, runs along lesser curvature
529473886	What 6 branches does the superior mesenteric branch into?	Inf. pancreaticoduodenal, jejunal and ileal branches, middle colic a., right colic a., ileocolic a., appendicular a.
529473887	What is another name for the marginal artery of the colon?	Artery of Drummond
529473888	What 3 branches does the inferior mesenteric artery branch into?	Left colic, sigmoid, superior rectal (hindgut)
