Definition

1. Noun:
   • Any of the five lobes forming the liver: A "hepatic lobe" is one of the major anatomical subdivisions of the liver. In humans, the liver is typically described as having five lobes: the right lobe, left lobe, caudate lobe, quadrate lobe, and a portion of the right lobe called the caudate process. These lobes are defined by surface markings, blood supply, and biliary drainage.

  • The surgeon carefully resected the damaged hepatic lobe.
  • An ultrasound can help visualize each distinct hepatic lobe.
  • The right hepatic lobe is the largest of the liver's lobes.

Advanced Usage
