Abdominal Viscera Part 2 Flashcards
What is the largest internal organ
liver
what is secreted by the liver
bile
What is stored by the liver
glycogen
What is the blood supply to the liver
75% portal vein
25% hepatic artery
What is the portal vein rich in
products of digestion
What is the hepatic artery rich in
O2
What is the venous drainage of the liver
hepatic veins
What is the coronary ligament of the liver
crown like ligaments on top of the liver
What is the function of the coronary ligaments of the liver
connect liver to diaphragm
What is the falciform ligament
ventral mesentery that connects liver to anterior abdominal wall
What is the ligamentum teres
obliterated umbilical vein
Where is the ligamentum teres found
going from liver to umbilicus
What is the porta hepatis
hilum of liver
What does the porta hepatis contain
hepatic artery
hepatic duct
portal vein
How are the portal lobes separated
by the functional lobes: each gets a distinct branch of portal triad contents
What are the fissures of the liver
right sagittal
left sagittal
transverse
What is found within the right sagittal fissure
IVC, gallbladder
What is found within the left sagittal fissure
ligamentum venosum groove/ligamentum teres groove
What is found within the transverse fissure
porta hepatis
What is the bare area of the liver
triangular surface on the superior surface of the liver where the liver is attached to the diaphragm via fat tissue; there is no peritoneum between liver and diaphragm
Other than the bare area of the liver, what other parts lack peritoneum
gallbladder bed
porta hepatis
What are the triangular ligaments of the liver
triangular reflections of visceral peritoneum where liver is attached to diaphragm
What type of blood is contained within the hepatic veins
processed portal blood reentering the caval circulation
Where do hepatic veins empty
IVC
What is innervation to the liver
vagus
T6-T9
What is innervation to the gallbladder
T6-T9
vagus
Where might gallbladder pain refer
shoulder due to phrenic nerve innervation
Is the pancreas intraperitoneal or retroperitoneal
retroperitoneal
Is pancreas endocrine or exocrine
both
How is pancreas exocrine
secretes juices into duodenum
How is pancreas endocrine
insulin glucagon into blood
What is arterial supply to the pancreas
pancreatoduodenal superior and inferior
pancreatic artery
Where is the portal triad found
hepatoduodenal ligament
What are the parts of the portal triad
hepatic artery
portal vein
hepatic duct
Describe the orientation of the structures within the portal triad
hepatic duct and artery are anterior
portal vein is more posterior
What structures combine to make the common hepatic duct
left and right hepatic ducts
What is the hepatopancreatic ampulla
dilated tube that receives the pancreatic duct and bile duct
What is the sphincter of Oddi
muscular valve that controls the flow of juices through the ampulla of Vater into the duodenum
What will result from blockage of the sphincter of Oddi
jaundice and bile back up
Where is spleen found
LUQ between ribs 9-11
What ligaments are associated with the spleen
splenorenal
gastrosplenic
What is the function of the spleen
removal of blood cells and formation of lymphocytes and antibodies
