Pancreas, Spleen, And Liver Flashcards
What are the three enzymes of the pancreas?
Amylase, Lipase, and protease
What is the Uncinate process?
Prolongation of the lower portion of the pancreas and left part of the head
What is enclosed by the head of the pancreas?
The SMA and SMV
Where does the tail of the pancreas end?
Near the spleen
What makes up the hepatoduodenal duct? What does it drain?
- The main pancreatic duct and the common build duct
- The main pancreatic duct drains the body and tail of pancreas
What drains the head of the pancreas?
Accessory pancreatic duct
Which duodenal papilla is associated with which duct?
Accessory - Lesser duodenal papilla
Main - Greater Duodenal Papilla
How do the splenic artery vein run in relationship to the pancreas?
Splenic Artery: Superior surface of pancreas
Splenic Vein: Posterior surface of pancreas
What are the main sources of blood supply to the pancreas?
Celiac Trunk: DP, ASPD, PSPD, IP, GP, CP
SMA: AIPD, PIPD
Where is the spleen located positionally?
Against the diaphragm and between ribs 9-11
Posterior to stomach and anterior to kidneys
What suspends the spleen in the abdominal cavity? What do they contain?
Gastrosplenic ligament (Contains short gastric and left gastroepiploic vessels)
Splenorenal ligament (Contains splenic vessels and tail of pancreas)
When present, where is the accessory spleen located?
Between the Gastrosplenic ligament
What dumps into the splenic vein?
- IMV
- Left Gastroepiploic vein
- Short Gastric Veins
- Pancreatic veins
Which lobe of the liver is nearest to the gall bladder?
Quadrate Lobe
What separates the left and right lobes of the liver?
Falciform ligament
Caudate and quadrate are part of the _________
Right lobe of liver
How does the Liver divide up functionally?
- Portal vein splits into right/left branch
- Common hepatic Duct relieves hepatic duct fro right/left halves
***Functional halves DO NOT correspond to lobes
Where might you be able to access the liver without going through a peritoneum?
Bare Area of liver:
- Visceral surface of liver
- Posterior near IVS
- Posterior RIGHT lobe
What happens to the falciform ligament at the visceral surface of the liver?
Divides into:
Coronary ligament —>Anterior/posterior
Right/left
What is the Ligamentum venosum and it’s significance?
Remnant of the ductus venosus in fetus which shunts blood flow of umbilical vein directly to inferior vena cava thus allowing oxygenated blood from placenta to bypass liver
What is the nerve supply to the liver?
Hepatic plexus via Celiac plexus
Where is the gall bladder located positionally?
- Fossa on visceral surface of liver
- Between right costal margin and right linea semilunaris at the transpyloric plan (RUQ L1)
Describe the pathway that dumps into the duodenum through the greater duodenal papilla.
Common bile duct + Main pancreatic duct (hepatopancreatic ampulla) —> Greater duodenal papilla —> 2nd part of duodenum
What controls the exit of bile through the bile duct?
The sphincter of Oddi
