The Portal Triad consists of:
Hepatic Artery
Hepatic Portal Vein

The portal triad is found in the..
…FREE EDGE of the LESSER OMENTUM.
Bilirubin is a product of the breakdown of..
… red blood cells.
The breakdown of red blood cells usually occurs in:
The spleen.
Bilirubin is used to form:
Bile.
The formation of bile, from bilirubin, occurs in the:
Liver.
Bile is stored and concentrated in the:
Gallbladder.
The pancreas excretes digestive enzymes into the:
2nd part of the duodenum.
What 3 branches trifurcate from the celiac trunk?
Splenic artery
Hepatic artery
Left gastric artery
The spleen is protected by which ribs?
Ribs 9-11
Where does the liver’s blood supply come from?
The hepatic artery
(Branches into right and left hepatic arteries)
Plus Hepatic Portal Vein!
(most of blood supplied by hepatic portal vein)
Which ribs protect the liver?
Ribs 7-11
What are the 4 anatomical segments of the liver?
Right lobe
Left lobe
Caudate lobe
Quadrate lobe
What supplies each functional segment (e.g. V) of the liver with blood?
Hepatic artery
Hepatic portal vein
Hepatic (bile) duct
Which of the following supplies the liver segments with blood?
Hepatic Vein
Hepatic Portal Vein
Hepatic Portal Vein
Which of the following drains blood from the liver segments?
Hepatic Vein
Hepatic Portal Vein
Hepatic Vein
Liver lobules contain:
A central vein in middle and an interlobular portal triad at each corner.
What does the “central vein” in a liver lobule do?
Collects “cleaned” blood and drains it into the hepatic veins.
What is a hepatocyte?
A liver cell.
Where does the bile that is formed in hepatocytes drain to (within the liver lobule)?
The bilary duct.
What 2 areas of the peritoneal cavity are clinically related to the liver?
Hepatorenal recess (Morison's pouch) Sub-phrenic recess
(These are both within the greater sac)
How does peritonitis lead to an abscess formation?
Peritonitis can result in a collection of pus in the recesses (hepatorenal and sub-phrenic), leading to an abscess formation.
When may a hepatorenal recess abscess be likely to form.?
When the patient is bedridden.
When the patient is supine.
(Because the Hepatorenal recess is one of the lowest parts of the peritoneal cavity when the patient is supine).
Where does the hepatic portal vein drain blood from.
The foregut, midgut and hindgut. (To the liver, for cleaning)
The splenic vein drains blood from the _______ to the _______.
The splenic vein drains blood from the foregut to the hepatic portal vein.
The inferior mesenteric vein drains blood from the ______ to the _________.
The inferior mesenteric vein drains blood from the hindgut to the splenic vein.
The superior mesenteric vein drains blood from the ______ to the _________.
The superior mesenteric vein drains blood from the midgut to the hepatic portal vein.
The inferior vena cava drains _____ blood from the _________ into the _____________.
The inferior vena cava drains cleaned blood from the hepatic veins into the right atrium.
What ligaments attach the liver to the diaphragm?
Coronary ligaments.
What ligament attaches the liver to the anterior abdominal wall?
Falciform Ligament.
What is the roll of the gallbladder (in relation to bile)? And when does this occur?
The gallbladder stores and concentrates bile.
In between meals.
The neck of the gallbladder narrows and becomes the…
Cystic duct.
