Coeliac trunk

The coeliac trunk is a branch of the aorta in the abdomen that supplies blood to the stomach, liver, gallbladder, pancreas, spleen and parts of the duodenum and oesophagus. It is important because its branches supply blood to important organs but also because stomach and duodenal ulcers can erode through these arteries and cause significant bleeding. The anatomy here is difficult to describe but let's try and describe the branches of the coeliac trunk and how they supply blood to the organs that they are reponsible for.
