The hepatic artery proper (also proper hepatic artery) is the artery that supplies the
liver
The liver is a major organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and biochemicals necessary for digestion and growth. In humans, it ...
and
gallbladder
In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although ...
. It raises from the
common hepatic artery
The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder.
It arises from the celiac artery and has the following branches:

, a branch of the
celiac artery
The celiac () artery (also spelled ''coeliac''), also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in ...

Structure
The hepatic artery proper arises from the common hepatic artery and runs alongside the
portal vein and the
common bile duct
The common bile duct, sometimes abbreviated as CBD, is a duct in the gastrointestinal tract of organisms that have a gallbladder. It is formed by the confluence of the common hepatic duct and cystic duct and terminates by uniting with pancrea ...
to form the
portal triad
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 a portal triad, hepatocyte ...
. A branch of the common hepatic artery –the
gastroduodenal artery
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum. It also indirectly supplies the pancreatic head (via the anterio ...
gives off the small
supraduodenal artery
The supraduodenal artery is an artery which usually branches from Gastroduodenal artery. This artery supplies the superior portion of the duodenum.

to the
duodenal bulb
The duodenal bulb is the portion of the duodenum closest to the stomach. It normally has a length of about 5 centimeters. The duodenal bulb begins at the pylorus and ends at the neck of the gallbladder. It is located posterior to the liver and the ...
. Then the
right gastric artery
The right gastric artery arises, in most cases (53% of cases), from the proper hepatic artery, descends to the pyloric end of the stomach, and passes from right to left along its lesser curvature, supplying it with branches, and anastomosing with ...

left gastric artery
In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus. The left gastric artery anastomoses with the right g ...

celiac trunk
The celiac () artery (also spelled ''coeliac''), also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) i ...
. It subsequently bifurcates into the right and left hepatic arteries.
Variant anatomy
Of note, the right and left hepatic arteries may demonstrate
variant anatomy. A misplaced right hepatic artery may arise from the
superior mesenteric artery
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the du ...

left gastric artery
In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus. The left gastric artery anastomoses with the right g ...
. The
cystic artery
The cystic artery (also known as bachelor artery) supplies oxygenated blood to the gallbladder and cystic duct.

In the classic arrangement, occurring with a frequency of approximately 70%, a singular cystic artery originat ...
generally comes from the right hepatic artery.
Other variants of right hepatic artery includes: arising directly from the proximal or middle part of common hepatic artery, gastroduodenal artery, superior mesenteric artery, celiac axis, aorta, splenic artery, or left gastric artery instead of arising from proper hepatic artery.
