Left lobe
Caudate lobe (superior)
Quadrate lobe (inferior)
Which of the lung lobes contains a bare area?
Quadrate lobe
What is meant by a “bare area”?

The porta hepatis is closely associated with the gallbladder at _______ aspect
posterior
How many functional divisions of the liver are there?
8
Why can individual functional lobes be removed from the liver?
Because each lobe has a branch of the hepatic artery, hepatic portal vein and bile drainage (to bile duct) and venous drainage (to IVC)
