Single layer squamous epithelium/single layer cuboidal epithelium

The beginning of the duct, directly connected to the acinus

thin

single layer tall columnar epithelium

LM: The nucleus is rounded at the top, the cytoplasm is eosinophilic, and the base is vertically striated.

EM: Plasma membrane infoldings and mitochondria (increases the surface area at the base of the cell, which facilitates water and electrolyte transport between cells and tissues)

Simple columnar epithelium→pseudostratified columnar epithelium

striated ducts merge into

interlobular duct: connective tissue between lobules

Common duct: opens into the mouth

Classification

Incomplete pipe wall

→Sublobular veins→Hepatic veins

Hepatocytes are an uneven plate-like structure arranged radially with the central vein as the center, and are cord-like in section.

The liver plate surrounding the liver lobules is called the boundary plate

Hepatocyte

Endothelial cells

liver macrophages

NK cells/intrahepatic large granular lymphocytes

The narrow area between liver sinusoidal endothelium and liver plate

filled with plasma

The place where liver cells and blood exchange substances

Lipid storage cells/hepatic stellate cells

Microscopic channels formed by local membrane depressions of two adjacent hepatocytes
