The first is the hepatic artery which delivers oxygenated blood from the general circulation. The second is the hepatic portal vein delivering deoxygenated blood from the small intestine containing nutrients. The blood flows through the liver tissue to the hepatic cells where many metabolic functions take place.

In the literature, the most frequently encountered variation is Type III, present in between 6% and 15.5% of all cases [12, 13]. The second most frequent variation, Type II, was reported in 2.5–10% of all cases [13, 14]. In our study too, Types III and II were the most commonly seen hepatic arterial variations.

What order is the hepatic artery?
Common hepatic artery It arises from the celiac artery, runs obliquely forward and towards the right, thereby forming a concave curve from the aorta. The common hepatic artery runs to the right, along the upper border of the pancreas to the left side of the portal vein.
What is the importance of Calot’s triangle?
It contains the cystic lymph node of Lund (also known as the Calot node); it is also where the cystic artery branches off the right hepatic artery. This triangular space is dissected to allow the surgeon to identify, divide, and ligate the cystic duct and artery.
What is the Hepatocystic triangle?

The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder.
Where does blood go from the hepatic artery?
Blood leaves the liver through the hepatic veins. This blood is a mixture of blood from the hepatic artery and from the portal vein. The hepatic veins carry blood to the inferior vena cava—the largest vein in the body—which then carries blood from the abdomen and lower parts of the body to the right side of the heart.
Where is the proper hepatic artery?
Gross anatomy The hepatic artery proper runs anteromedial to the portal vein and medial to the common bile duct to form the portal triad within the hepatoduodenal ligament 1. It terminates by bifurcating into the right and left hepatic arteries before entering the porta hepatis of the liver.
