So if we look at the blood supply
to the pancreas and the spleen.
Again we need to look at the coeliac trunk. We can see
the coeliac trunk is giving rise to whole series of blood vessels.
It gives rise to a big branch that runs along
the posterior aspect of the pancreas towards the spleen
and that's the splenic artery.
Coming off the splenic artery we have some small
branches that supply the body and tail
and neck of the pancreas.
But importantly at the head region we have
what are known as the pancreaticoduodenal arteries.
So here we can see the pancreaticoduodenal arteries.
They supply the pancreas and the duodenum.
We have a superior pancreaticoduodenal artery
and that comes from the coeliac trunk
by way of various branches of gastroduodenal.
And that has superior pancreaticoduodenal artery as anterior
and posterior branches which we can see
running on the anterior and the posterior
surface of the pancreas and the duodenum.
Coming from the superior mesenteric artery
we also have inferior pancreaticoduodenal arteries
and these themself have anterior and posterior branches
which supply the anterior and posterior surface
of the duodenum and the pancreas.
We will explore these in more detail
when we look at the arterial supply to the
gastrointestinal tract in a later lecture.
