The liver is divided into a large right lobe and a small left lobe, which are divided into smaller parts called hepatic ________ that contain macrophages and hepatocytes.

Hepatic Lobules

The microscopic functional units of the liver, consisting of a hexagonal arrangement of liver cells (hepatocytes) centered around a central vein.

Macrophages

A type of phagocytic cell found in the liver, spleen, lungs, bone marrow, and connective tissue. Macrophages play several roles in humoral and cell-mediated immunity, including presenting the antigens to the lymphocytes involved in these defenses; also known as monocytes while in the bloodstream.

Hepatocytes

The cells within the lobules of the liver. Hepatocytes process nutrients in the blood and make bile.
