Liver histology
Make it clearer
Under a microscope, the liver can be pictured as a mosaic of units called lobules. A central vein sits in the middle of each unit, with hepatocytes arranged in cords around it.
Sinusoids run between those cords. These are thin-walled, fenestrated vascular spaces. At the edges of each lobule are portal triads, groups of three small channels: a branch of the bile duct, a branch of the portal vein, and a branch of the hepatic artery.
In brief
Under the microscope, liver tissue is organized into units called lobules. A central vein lies at the center of each lobule, with hepatocytes arranged around it.
The hepatocytes form cords around the central vein. Between these cords run sinusoids, vascular spaces with thin, fenestrated walls.
Portal triads appear at the edge of each lobule. Each triad contains three structures: a branch of the bile duct, a branch of the portal vein, and a branch of the hepatic artery.
