What is segment 6 of the liver?
segment 6 (VI) is located below the portal plane to the right of the right hepatic vein. segment 7 (VII) is located above the portal plane to the right of the right hepatic vein. segment 8 (VIII) is located above the portal plane between the middle and right hepatic veins.
How many segments are in the liver according Couinaud nomenclature?
Couinaud classification. The Couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments. Each segment has its own vascular inflow, outflow and biliary drainage. In the centre of each segment there is a branch of the portal vein, hepatic artery and bile duct.
How do you separate the segments of the liver?
A horizontal plane further divides the liver, known as the portal plane where the portal vein bifurcates and becomes horizontal, dividing each section (or sector) of the liver into superior and inferior segments: left lateral section: segment 2 above and segment 3 below the portal plane.
What is excreted from the liver?
The liver is a very important organ of excretion. The liver breaks down many substances in the blood, including toxins. The liver also excretes bilirubin — a waste product of hemoglobin catabolism — in bile. Bile then travels to the small intestine , and is eventually excreted in feces by the large intestine .
Is there a right and left liver?
Anatomically, the liver is divided into a larger right lobe and a smaller left lobe by the falciform ligament (see the image below).
Do liver lobes grow back?
The liver is the only visceral organ that possesses the capacity to regenerate. The liver can regenerate after either surgical removal or chemical injury.
How is the liver divided into anatomical lobes?
Each lobe is divided into 2 sectors. The right hepatic vein (RHV) divides the right lobe into anterior and posterior sectors; the left hepatic vein (LHV) divides the left lobe into medial (quadrate) and lateral sectors.
