Jul 16, 2023 · The hepatic artery carries oxygenated, nutrient-poor blood to the liver whereas the portal vein carries nutrient-rich, oxygen-poor blood to the liver. The blood then flows through the liver and provides it with oxygen and nutrients.

Jan 31, 2025 · The liver is unique among organs in that it receives blood via two distinct circulatory routes: systemic circulation and hepatic portal circulation. Each of these routes provides blood of differing compositions that allow the liver to perform its unique and vital digestive and metabolic functions.

Diagram (A) and a 3D volume rendered CTA (B) showing conventional hepatic artery anatomy. Note in the CTA there is middle hepatic artery (MHA) and only a stub of LGA (black arrow) is shown.

1 day ago · It delivers oxygen-rich blood from the systemic circulation, originating from the celiac trunk and branching into the right and left hepatic arteries. This arterial supply constitutes approximately 25% of the liver’s blood flow, yet provides nearly half of the liver’s oxygen requirements, underscoring its importance.

Jan 24, 2025 · The common hepatic artery originates from the celiac trunk, a major arterial branch of the abdominal aorta. The celiac trunk arises at the level of the twelfth thoracic vertebra (T12), just below the diaphragm, and divides into three main branches: the left gastric artery, splenic artery, and common hepatic artery. [8]

Oct 30, 2023 · The blood supply of the liver is delivered through the portal vein and the proper hepatic artery. The proper hepatic artery (arises from the celiac trunk via common hepatic artery) brings oxygenated blood to the hepatic tissues, while the portal vein collects the deoxygenated blood from the abdominal contents and filters it, eliminating toxins ...

Identify on a diagram and be able to describe the liver’s blood supply: hepatic artery, hepatic portal vein, hepatic vein. Identify on a diagram and be able to describe the function of the cells and structures in a liver lobule: hepatocytes, Kupffer cells, hepatic sinusoids, bile canaliculi, central vein, portal triad (hepatic triad).

Utilizing micro-computed tomography images, the hierarchical structure, interbranch segment lengths and diameters of a hepatic artery, a portal vein, and two biliary trees from intact rat liver...

Aug 15, 2020 · The hepatic artery, being a muscular member of the systemic circulation, is affected by all sorts of clearly defined regulatory mechanisms. If one had to classify them, they would fall into two messy overlapping categories:
