Digestive Glands pt 2 Flashcards
Bile exits the liver through what structure?
Horizontal fissure/porta hepatic region
The portal structures occupy a section of the lesser omentum that is divided into 2 parts:
Hepatic gastric ligament and hepatic duodenal ligament
Ligament connecting the liver the the stomach
hepatic gastric lig
Ligament connecting the liver (horizontal fissure) to the first segment of the duodenum
Hepatic duodenal lig
Describe the spatial arrangment of the hepatic vessels
Hepatic artery closer to midline, bile duct to right, and portal vein posterior to both
What is unique about the liver’s portal venous system?
Takes both venous and arterial blood supply into SAME capillary bed–allowing MIX
____ drains blood from the gut tube into the liver
Portal Vein
The blood entering the portal vein is __
deoxy and nutrient-rich
The blood from the portal vein is processed in the liver and returned to the heart via the ________
Hepatic veins (and into IVC)
Blood form the hepatic veins empty into
IVC (before pass through diaphragm and into right atrium)
Where is the pancreas located in comparison to the stomach?
Posterior–embedded in posterior abd wall
Describe shape/boundaries of pancreas:
Head: greater curve of duodenum (head and neck anterior to vert colum)
Body: extends to left side of abd
Tail: pointed toward spleen’s hilum (share supply) (body and tails curve left and post, pointing toward spleen)
Uncinate Process: hook-like process beneath neck with no specific function
T/F: The pancreas is both endocrine and exocrine
True
Pancreas connects to alimentary canal through ducts in ___ segment of duodenum
second segment (through the lesser curvature)
T/F: The pancreatic duct follows the same path as the bile duct
True (both connecting at second seg of duodenum)
The lesser sac (omental bursa) in located ____ the stomach and ____ the pancreas
behind stomach and anterior to pancreas
What part of pancreas remains mesenteric?
tail
Bile duct and pancreatic duct share common connection _____
hepatopancreatic ampulla (carries mix of bile and pac secretions)
Accessory pancreatic duct is variable present and carries:
ONLY panc secretions
The pancreas is a ___ derivative.
–positioned near the foregut/midgut transition (bet 2 and 3 segment of duodenum)
foregut
Foregut blood supply:
Celiac artery supplies most of pancreas
Midgut supply: Superior Mesenteric Artery supplies _____ of the pancreas and duodenum
head
Body and Tail of pancreas are supplied by the _____
Splenic artery (suns on superior border of pancreas)
Superior Pancreaticoduodenal arteries (branch of gastroduodenal) anastomse with Inferior Pancreaticoduodenal Arteries (branch of Superior Mesenteric) at ______
Foregut-midgut transition (near panc head and lesser curve of duodenum)
Duodenal Papillae and Duct openings are in what segment?
2nd segment of duodenum
–marks opening of accessory pancreatic duct
–Found higher in second segment of duodenum
Minor Duodenal Papilla
–marks opening for Hepatopancreatic Ampulla (Ampulla of Vater)
Major Duodenal Papilla
where bile and panc secretions mix before entering lumen
Hepatopancreatic Ampulla (Ampulla of Vater)
The Duodenum is ___ aas well as almost all of the pancreas
secondarily retroperitoneal
What part of the pancreas remains mesenteric?
tail (located within liorenal ligament)
Ligament containing the spenic artery and vein, connecting the spleen to the posterior abdominal wall
—only portion of pancreas remains mesenteric
liorenal ligament (headed for the hilum of the spleen)
Pancreas Peritonal covering is ___ because of the way it is innervate. Result?
Parietal….pain sensitive!
T/F: The splenic artery becomes retroperitoneal along with the majority of the pancreas
True
Supplies the body and tail of the pancreas
Splenic Artery (first part is retroperitoneal but beomes mesenteric at tail of pancreas)
Main artery supplying foregut structures
Celiac Artery
The spleen is located ___ to the stomach and attached via ________
left of the stomach; attached via gastric splenic ligament and lionalrenal ligament (splenic vessels traverse these ligaments)
Lesser Sac formed by lesser omentum divided into:
Hepatogastric ligament and Portohepatic Ligament
Attaches to lesser curve of stomach and contains left and right gastric arteries (ligament)
Hepatogastric ligament
Gastric Splenic Ligament and Lionalrenal ligament contribute to the ___ wall of the lesser sac
left wall
T/F: the pancreas lies within the lesser sac, posterior to stomach and posterior abd wall covered by parietal peritoneum
True
T/F: The spleen is a mesodermal lymphoid organ
True (NOT a gut derivative)
Spleen location:
Left upper quad of abdomen, posterior to stomach and protected by rib cage
T/F: The spleen is entirely coveref with visceral peritoneum
True (hanging from a couple mesenteries)
2 Key ligaments of the Spleen:
Lienorenal Ligament (spleen to post ab wall–carries blood supply) abd Gastrosplenic Ligament (connects spleen to stomach greater curv with short gastric arteries and veins running through it)
T/F: Pancreatitis can cause visceral and somatic pain
True (Visceral: Splanchnic nerves–inflam and distent) (Somatic: irritates peritoneal)
