Lobus quadratus
DigestiveOrgansAbdomen
- What it is
- Rectangular area of the visceral surface in front of the porta hepatis, between the gallbladder fossa and the fissure for the ligamentum teres.
- Function
- Hepatocytes make bile, process nutrients arriving in the portal vein, store glycogen and vitamins, build plasma proteins such as albumin and clotting factors, and detoxify drugs and ammonia.
- Size
- About 5 cm long and 3 cm wide (segment IVb).
- Clinical note
- Although classically counted with the right lobe, its blood supply and bile drainage come from the left branches, so functionally it belongs to the left liver.
