The hepatic lobule is a building block of the liver tissue, consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein. Lobules are different from the lobes of liver: they are the smaller divisions of the lobes.

Aug 8, 2023 · Together with the bile duct, the hepatic portal vein and hepatic artery form the portal triad. Those structures supply blood to the sinusoids and the hepatocytes, subsequently draining into the central vein followed by the sublobular veins.

Sep 17, 2024 · The portal triad offers sufficient blood supply to the liver. In addition, it also increases bile flow from the gallbladder to the lumen of the duodenum. The portal vein provides about 75% of the liver’s blood supply.

Feb 13, 2025 · In this article, we shall look at the anatomy of the liver – its position, structure, and neurovascular supply. Explore, cut, dissect, annotate and manipulate our 3D models to visualise anatomy in a dynamic, interactive way. The liver is predominantly located in the right hypochondrium and epigastric areas and extends into the left hypochondrium.

May 1, 2023 · The functional unit of the liver is the lobule. Each lobule is hexagonal, and a portal triad (portal vein, hepatic artery, bile duct) sits at each corner of the hexagon. The foundation of the lobule is composed of hepatocytes, which have …

Nov 26, 2022 · These sinusoids contain Kupffer cells, the resident macrophage of the liver, and stellate cells, which are hepatic lipocytes. At the vertices of the hexagon is a triad of a bile duct branch, a portal vein branch, and a hepatic artery branch, referred to as a portal triad.

The inlet flow comes from the hepatic artery and the portal vein constituting the triad (the third element being the bile canal). The outlet flow (hepatic vein) is located at the center of each lobule.

Portal Triad. Scanning electron micrograph (SEM) of a portal triad in the liver. A distinctive component of a hepatic lobule found running along each of the lobule’s corners. Portal triads are composed of branches of three vessels: Hepatic Artery (red) - …

Histology of the liver - lobules, central veins, hepatocytes, portal triads (hepatic arteries, portal venules, bile ductules), and bile ducts.

Scanning electron microscopy (SEM) of a portal triad in the liver. The following three vessels are bundled together and found at the corners of the hexagonally shaped hepatic lobules. A continuous wall of hepatocytes surrounds the portal area. The term “portal triad” is a bit of a misnomer because it implies only three components.
