W4 Liver, Stomach, Spleen & Pancreas Flashcards
What is the largest internal organ in the body
liver
Where does the liver mainly lie
right hypochondrium, close to the diaphargm
What protects the liver
rib cage
How many lobes does the liver have
4
What is the largest lobe of the liver
right lobe
What is the liver a derivative of
embryonic foregut
Where does the liver receive its blood from
coeliac trunk
What does 70% of the blood supply to the liver come from
hepatic portal vein
Describe 70% of the blood arriving at the liver
nutrient rich venous blood
What a function of the liver (bile)
synthesises and secretes bile into the duodenum
How does the liver secrete bile into the duodenum
through the common bile duct
Where does the quadrate lobe of the liver sit
lower visceral surface, between gall bladder and fossa
Where does the caudate lobe of the liver sit
upper visceral surface, between inferior vena cava and fossa
What is the bare area of the liver
change in texture on posterior surface, where coronary ligaments have pealed back
What is the function of the triangular ligaments
attach the left and right lobes to the diaphragm
What is the function of the falciform ligament
divides left and right lobes
What type of structure is the gall bladder
intraperitoneal
What is the function of the gall bladder
concentrate and store bile
Where does the gall bladder lie
right hypochondrial region of the abdomen
What is the function of the vena cava in reference to the liver
takes blood from the liver back to the heart
What is the function of the hepatic artery
supplies non-parenchymal structures of liver with blood
What is the hepatic artery derived from
coeliac trunk
What is the dominant blood supply of the liver
hepatic portal vein
What does the hepatic portal vein allow the liver to perform
detoxification
What is the function of the hepatic veins
collect venous blood
What do the hepatic veins drain into
vena cava
What is the function of the hepatic duct
drain bile from the liver
What is the function of the coronary ligament
suspend liver from the diaphragm
What is the function of the cystic duct
connect gall bladder to hepatic duct
What is the function of the porta hepatis
separates the caudate and quadrate lobes
Describe the porta hepatis
deep transverse fissure
At what level does the oesophagus penetrate the diaphragm
T10
What are the four regions of the stomach
cardiac, pylorus, body and fundus
What regions of the stomach serve as a reservoir for food
fundus and body
What region does the oesophagus enter the stomach
cardiac
Where is the food broken down into chyme
pyloric antrum
What is the function of the pyloric sphincter
separate stomach from duodenum
What nerve supply does the stomach receive
vagus nerve
Where does the vagus nerve enter the abdomen
either side of the oesophagus
Describe the sympathetic innervation of the stomach
coeliac plexus supplies the stomach with sympathetic fibers
What does the coeliac plexus surround
root of coeliac trunk
How many arteries supply the stomach
4
What arteries supply the lesser curvature of the stomach
right and left gastric
What arteries supply the greater curvature of the stomach
right and left gastro-epiploic
What are rugae
folds to increase surface area
Where are rugae mainly found
body of the stomach
What do rugae aid
churn up of food
Where does the pancreas lie
posterior abdominal wall behind the stomach
What are the regions of the pancreas
head, neck, body, tail and uncinate process
Where does the body of the pancreas lie
left of the midline
What does the tail of the pancreas reach
hilium of the spleen
What blood vessels supply the pancreas
branches of the coeliac artery - splenic artery
Where does the pancreas receive additional blood supply from
Superior mesenteric artery
Where does the head of the pancreas sit
curve of the duodenum
Where does the aorta and vena cava pass in reference to the pancreas
posteriorly to the head
Where does the spleen lie
left hypochondrium, mid axillary line adjacent to 9th and 11th ribs
What is a unique characteristic of the spleen
notched anterior border
What supplies the spleen with blood
splenic artery
What vein does the splenic vein join onto
inferior mesenteric vein
What are splenic nodules
common non cancerous lesions found in the spleen - clotted blood
What is the portal triad composed of
hepatic artery, hepatic vein, bile ductule
