GENERAL HISTOLOGY

Detailed explanation-1: -Final answer: Hepatic Lobules are the structural and functional unit of the liver.

Detailed explanation-2: -Each lobule is made up of numerous liver cells, called hepatocytes, that line up in radiating rows. Between each row are sinusoids. These small blood vessels diffuse oxygen and nutrients through their capillary walls into the liver cells.

Detailed explanation-3: -Functional Units: Acinus and Lobule The acinus is a unit that contains a small portal tract at the center and terminal hepatic venules at the periphery. It is the smallest functional unit and is divided into zones 1, 2, and 3, wherein zone 1 surrounds the portal tract and zone 3 surrounds the hepatic venule.

Detailed explanation-4: -The multiple tasks of the liver are not split up between them: every hepatocyte cell is capable of carrying out several functions. Hepatocytes are split up into groups of lobules. These are the functional units of the liver. There are up to a million lobules in the liver.

Detailed explanation-5: -The hepatic lobule is the anatomic unit of the liver. In the anatomic model, liver lobules are organized into irregular polygons demarcated by connective tissue and composed of plates of hepatocytes radiating outward from the central vein to the portal triads (Figure 61-1).
