hepatic artery
hepatic portal vein

venous drainage
bile drainage

Question 28

venous drainage from the liver

via 3 main hepatic veins into the IVC

Question 29

describe the IVC and hepatic veins

Answer 29

lack valves

Question 30

hepatomegaly

Answer 30

a rise in central venous pressure is directly transmitted to the liver
it enlarges as it engorges with blood

Answer 33

one of the lowest parts of the peritoneal cavity when the patient is supine

Question 34

venous drainage of the liver - hepatic portal vein

Answer 34

drains blood from foregut, midgut and hindgut to the liver for first pass metabolism
