Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The duodenum receives blood supply from two main arterial sources.
The first and second parts are mainly supplied by the superior pancreaticoduodenal artery, which is a branch of the gastroduodenal artery.
The third and fourth parts are supplied by the inferior pancreaticoduodenal artery, which arises from the superior mesenteric artery.
The supraduodenal artery only supplies the superior portion near the duodenal bulb.
The gastroduodenal artery is the parent artery but does not directly supply the third part.
Therefore, the third part is supplied mainly by the inferior pancreaticoduodenal artery.
The first and second parts are mainly supplied by the superior pancreaticoduodenal artery, which is a branch of the gastroduodenal artery.
The third and fourth parts are supplied by the inferior pancreaticoduodenal artery, which arises from the superior mesenteric artery.
The supraduodenal artery only supplies the superior portion near the duodenal bulb.
The gastroduodenal artery is the parent artery but does not directly supply the third part.
Therefore, the third part is supplied mainly by the inferior pancreaticoduodenal artery.
