Full Blood Supply to the Liver and Gallbladder Description
[Continued from above] . . .
The gallbladder's blood is supplied by the cystic artery. The cystic artery originates in the right hepatic artery. The cystic artery also supplies the cystic duct; at this point it breaks up into two or four minor branches (these are called Calot's arteries), which supply blood to the gallbladder's cervix and to part of the cystic duct. Then these arteries divide into the superficial branch, which crosses over the left face of the gallbladder and the deep branch, which goes in between the gallbladder and the gallbladder fossa.
