The hepatic plexus is a sympathetic and parasympathetic nerve plexus that provides innervation to the parenchyma of the liver as well as contributing innervation to some other abdominal structures. Its sympathetic component is derived from the coeliac and superior mesenteric plexuses; its parasympathetic component is derived from the anterior ...
The hepatic vein subsequently drains into the inferior vena cava. The hepatic artery provides 30 to 40% of the oxygen to the liver, while only accounting for 25% of the total liver blood flow. The rest comes from the partially deoxygenated blood from the portal vein. The liver consumes about 20% of the total body oxygen when at rest.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. 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 .
A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.
proper hepatic artery (entering) hepatic portal vein (entering) The hepatic duct lies in front and to the right, the hepatic artery to the left, and the portal vein behind and between the duct and artery. It also transmits nerves and lymphatics. Sympathetic nerves - these provide afferent pain impulses from the liver and gall bladder to the brain.

Hepatic branches which supply the liver, [3] [1] gallbladder, and biliary apparatus. [1] Celiac branches which contributes parasympathetic afferents to the celiac plexus. [1] Anterior gastric branches which supply the stomach. [3] [1] Anterior and posterior nerves of Latarjet which innervate the pylorus, and proximal duodenum. [1]
Between the two layers of the lesser omentum, close to the right free margin, are the hepatic artery proper, the common bile duct, the portal vein, lymphatics, and the hepatic plexus of nerves—all these structures being enclosed in a fibrous capsule (Glisson's capsule).
