A

Starts at cardiac notch and ends at pyloric antrum

22
Q

What indictaes the junction of the body and pyloric region?

A

Lesser curvature

23
Q

Which ligament attaches at the lesser curvature?

A

Hepatogastric ligament

24
Q

Generally, what is the blood supply of the stomach?

A

Coeliac trunk

25
