6. Fissures

Question 2

What do portal veins do?

Answer 2

Return nutrient rich (oxygen poor) blood from the spleen, pancreas and intestines

Question 3

What does the hepatic artery do?

Answer 3

Supplies oxygen rich (nutrient poor) blood to the liver from the celiac trunk/aorta

Question 4

Question 6

What are fissures?

Answer 6

Anatomical divisions

Question 7

What does the liver receive?

Answer 7

Answer 8

75%

Question 9

What percentage does the hepatic artery take up?

Question 10

What happens in hepatic veins? (2)

Answer 10

1. Blood from the portal veins and hepatic arteries mix as they travel though the liver sinusoids/lobules
2. This blood gets picked up by the hepatic veins before returning to the heart via the IVC
