GENERAL HISTOLOGY

Detailed explanation-1: -Anatomically the liver has four lobes: right, left, caudate, and quadrate. The quadrate lobe is located on the inferior surface of the right lobe. The caudate lobe is located between the left and right lobes in an anterior and superior location.

Detailed explanation-2: -The liver consists of 2 main lobes. Both are made up of 8 segments that consist of 1, 000 lobules (small lobes). These lobules are connected to small ducts (tubes) that connect with larger ducts to form the common hepatic duct.

Detailed explanation-3: -The liver has two lobes-the right and the left. Each lobe is made up of thousands of hexagonally-shaped lobules. These lobules are very small. Each lobule is made up of numerous liver cells, called hepatocytes, that line up in radiating rows.

Detailed explanation-4: -Segment IV is the medial segment of the left lobe. Segments II, III, and IV collectively make up the functional left lobe of the liver. The functional right lobe of the liver is made up of segments V and VIII, the anterior segments, and segments VI and VII, the posterior segments.
