between the peritoneal layers

False, it is a fibromuscular ligament.
What is the purpose of the suspensory ligament of Treitz?
It keeps the juodenaljejunal junction from sagging
What is the purpose of the mesocolon?
It anchors portions of the colon to the posterior abdominal wall.

How is the ascending and descending colon anchored?
It is attached directly to the posterior wall
How is the transverse colon anchored?
Via the transverse mesocolon
How is the sigmoid colon anchored?
Via the sigmoid mesocolon

Clinically speaking, what can accumulate in the peritoneal pouches?
What is the hepatorenal pouch bound by? (4 things)
the liver, right kidney, colon, and duodenum
Which one is more superior, the hepatorenal pouch or rectovesical/rectouterine pouch?
the hepatorenal pouch
Know how the pouches can drain into each other.
Where is the rectovesical/rectouterine pouch located?
between the rectum and uterus
What is the liver's job?
detoxifies chemical products and produces bile
What is the gall bladder's job?
stores bile for emulsification of fats
What does the pancreas do?
It produces enzymes for digestion
What does the spleen do?
It produces lymphocytes and filters blood
What does the stomach do?
It stores food prior to entering the duodenum
What does the small intestine do?
It is for primary chemical digestion
What does the large intestine do?
it is secondary for chemical digestion
What is the kidney's job?
Filter waste products out of blood
What do the adrenal glands do?
Cortex that produce steroid hormones and medulla acts as a sympathethic ganglia
The gallbladder is attached to what, where?
To the inferior surface of the liver
The gallbladder receives ___ produced by the liver via bile ducts.
Bile drains into the _______ through bile ducts.
T/F, right and left hepatic ducts receive bile from right and left lobes of the liver?
The common hepatic duct receives what?
Bile via the right and left hepatic ducts
T/F the cystic duct is connected to the duodenum?
False, it runs into the common hepatic duct
The common bile duct receives which ducts?
The cystic and common hepatic ducts
The common bile duct joins the ___ _______ ___.
main pancreatic duct
Both the common bile and main pancreatic ducts empty into the ______ ______ _____.
Major duodenal papilla
What are the 5 regions of the pancreas?
Where does the main pancreatic duct enter?
The duodenum at the major duodenal papilla
T/F the pattern of pancreatic drainage is set.
False, it's variable
The spleen has a diaphragmatic surface along which ribs?
The celiac trunk supplies which structures?
The liver, gallbladder, esophagus, stomach, pancreas, & spleen
What are the three main branches of the celiac trunk?
The common hepatic
The left gastric
The splenic artery
What are the two terminal branches of the common hepatic artery?
What is the course of the proper hepatic artery?
As the superior branch of the hepatic artery, it runs towards the liver, medial to the bile duct and then it splits into right and left hepatic arteries
What is the inferior branch of the common hepatic artery?
The gastroduodenal artery
Where does the gastroduodenal artery run toward and what are its branches?
The gastroduodenal artery runs towards the junction of the stomach and duodenum.
1. Pancreaticoduodenal artery- supplies pancreas, duodenal
2. Right gastroepiploic- supplies the greater curvature of the stomach
The left gastric artery is the ______ branch of the celiac trunk.
The left gastric artery runs left towards the ____ ___ ___ ___ ____?
Lesser curvature of the stomach
What does the left gastric artery supply?
the stomach and esophagus (via esophageal branches)
The splenic artery runs towards the ____.
The splenic artery supplies what two structures?
the pancreas and the spleen
What arteries supply the greater curvature of the stomach and what are they branches of?
The short gastric and the left gastroepiploic arteries are branches of the splenic artery and supply the greater curvature of the stomach
T/F, there are many common variations of the hepatic artery.
