classic hepatic lobule

Answer 9

hexagonal lobule
surrounding a central vein
portal triads at angles

Question 10

portal lobule

Answer 10

triangular arrangement
center of the triangle is bile duct collecting from 3 hepatic lobules
angle are the central veins of three hepatic lobules

Question 11

liver acinus

Answer 11

based on the oxygen gradient of venous sinusoids of adjacent lobules
3 zones based on blood supply to hepatocytes

Question 12

microscopic structure of lobule

Answer 12

sinusoids are b/w rows of hepatocytes and they supply blood to the liver cells
bile flows opposite of blood
