Name the branches of the common hepatic artery
Hepatic artery proper, right gastric, gastroduodenal a.
What happens after the splenic artery supplies the spleen?
It gives rise to short gastric arteries and the left gastroepiploic artery
What do the short gastric arteries supply? Where do these arteries arise from?
Supply fundus of stomach
Celiac artery-> splenic a. -> short gastric a.
How do you find the gastroduodenal artery?
It branches off the common hepatic a. and goes behind 1st part of the duodenum
What does the gastroduodenal a. Split into?
