    00:00 Here we just have a schematic which is going through the various branches that come from the coeliac trunk that I have already spoken about. So we have seen the coeliac trunk that's coming at T12. That gives rise to three branches. It gives rise to the left gastric the splenic and the common hepatic.

    00:20 The left gastric may give rise to an oesophageal branch that runs up and supplies the oesophagus We can see that the common hepatic artery this is going to divide into the gastroduodenal artery, which we spoke about, and the hepatic artery proper.

    00:38 It’s the hepatic artery proper that is going to supply the gallbladder via the cystic artery.

    00:44 It goes to supply the liver via the right and left hepatic arteries.

    00:48 And it gives rise to the right gastric. And it’s the right gastric and the left gastric that run along the lesser curvature of stomach, the lesser curvature of the stomach.

    01:04 If we go to the gastroduodenal artery, we know that gastroduodenal artery gives rise to the superior pancreatcioduodenal which then has its anterior and its posterior branches that go anterior and posterior to the head of the pancreas and the duodenum. It also gives rise to the right gastroomental artery.

    01:24 And the right gastroomental artery is going to run along the greater curvature of the stomach; where it anastamoses with the left gastroomental artery.

    01:36 And we know the left gastroomental artery comes from the splenic.

    01:40 So we can see we have these anastomotic loops, two of them, originating from the coeliac trunk that goes around the stomach. We have one left gastric right gastric, hepatic artery proper, common hepatic back to the coeliac trunk.

    01:59 We then have a second which is the splenic, left gastroomental right gastroomental, gastroduodenal comon hepatic, coeliac trunk.

    02:09 We have two anastomotic loops running around the stomach.

    By oktay cem K. on 15. January 2018 for Coeliac Trunk: Branches – Arterial Supply to the GI Tract

    This diagram sums up everything and really helpful. I will do this kind of diagram for every arterial supplies. Thank you for giving me the idea. Really appreciated
