GI - Why might my patient be jaundiced? Flashcards
The Portal Triad consists of:
Hepatic Artery
Hepatic Portal Vein
Common bile duct
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)
