Liver histology: Structure, cells and characteristics | Kenhub
WEBAug 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.
Porta hepatis - Kenhub
WEBFeb 16, 2024 — The bile duct, hepatic artery, and hepatic portal vein together constitute the portal triad. This triad runs between the layers of the hepatoduodenal ligament to enter the liver at the porta hepatis.
Hepatic portal vein: Anatomy, function, clinical points - Kenhub
WEBOct 30, 2023 — These portal venule branches run alongside hepatic arterioles in the spaces between the liver lobules, and these two vessels, along with a (common) bile duct, form the hepatic portal triad. These vessels all empty eventually into the hepatic sinusoids to supply blood to the liver, which also means that there is an unusual mixing of venous and ...
Portal Triad - medcell.org
WEBPortal Triad. Portal triads are composed of three major tubes. Branches of the hepatic artery carry oxygenated blood to the hepatocytes, while branches of the portal vein carry blood with nutrients from the small intestine.
Anatomy, Abdomen and Pelvis: Liver - StatPearls - NCBI Bookshelf
WEBNov 26, 2022 — 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. Blood flows from the portal vein branch and hepatic artery branch across the lobule and finally into the central vein, a branch of the hepatic vein.
Liver Structure and Function - Liver Structure and Function
WEBOverview of liver structure. At the cellular level, portal triads consist of adjacent and parallel terminal branches of bile ducts, portal veins, and hepatic arteries that border the hepatocytes. Terminal branches of the hepatic veins are in the center of hepatic lobules.
Portal Triad: Essential Structures and Associated Diseases
WEBSep 17, 2024 — The portal triad consists of three important structures that play a key role in blood supply. It contains the extrahepatic structures, including portal vein, hepatic artery, and bile ducts. The hepatic artery is a branch of the common hepatic artery.
Physiology, Liver - StatPearls - NCBI Bookshelf
WEBMay 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 physiologically distinct apical and basolateral membranes.
Anatomy and Physiology of the Hepatic Circulation
WEBJan 1, 2014 — The six portal triads in the corners of the lobule harbour portal veins (blue), hepatic arterioles (red) and bile ductules (green). Upon entry into the lobule, the portal venous and arterial blood sources merge and flow from the periphery along the sinusoids towards the central vein.
The liver, a functionalized vascular structure - PMC
WEBOct 1, 2020 — 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.
