Q. All of the following reasons can explain why most peptic ulcers, like Mr. Volpe's, occur in duodenum EXCEPT which statement? I have ruled out 2 of the answers and I am down to 2.
The first one is
a) Bicarbonate-rich pancreatic juice is secreted after the acidic chyme enters the duodenum
or b) Normally the duodenum lacks a mucosal layer. (originally I was leaning to this...but now I'm unsure)?
