Overview - Hepatic Circulation - NCBI Bookshelf
Liver blood flow determines liver parenchymal cell volume by a mechanism that is based on the effect of hepatic blood flow to generate shear stress on hepatic endothelium, with the result being nitric oxide generation and triggering of the hepatic regeneration cascade .
Liver: Blood supply, innervation and anatomy - Kenhub
Oct 30, 2023 · The blood supply of the liver is delivered through the portal vein and the hepatic artery. The hepatic artery brings oxygenated blood to the hepatic tissues, while the portal vein collects the deoxygenated blood from the abdominal contents and filters it.
Liver blood flow: Physiology, measurement, and clinical ...
Apr 9, 2015 · This chapter outlines the physiologic control of the liver’s blood supply, describes the techniques used for its measurement in both human and animal models, and explores its function in various clinical situations.
Regulation of hepatic blood flow: The hepatic arterial buffer ...
Among parenchymal organs, blood flow to the liver is unique due to the dual supply from the portal vein and the hepatic artery. Knowledge of the mutual communication of both the hepatic artery and the portal vein is essential to understand hepatic physiology and pathophysiology.
Liver: Anatomy and Functions | Johns Hopkins Medicine
Nutrient-rich blood flows in from the hepatic portal vein. The liver holds about one pint (13%) of the body's blood supply at any given moment. The liver consists of 2 main lobes. Both are made up of 8 segments that consist of 1,000 lobules (small lobes).
