Course
The right gastric artery typically arises from hepatic artery proper (although can also originate from the common hepatic artery or left hepatic artery).
After its origin, the right gastric artery passes anteriorly and to the left, travelling between the two layers of the hepatogastric ligament (part of the lesser omentum). It travels along the lesser curvature of the stomach, where branches arise at right angles to supply the organ.
The right gastric artery terminates by anastomosing with the left gastric artery.
