Which of the following statements is not correct?

  1. Oxyntic cells are present in the mucosa of stomach and secrete HCl.
  2. Acini are present in the pancreas and secrete carboxypeptidase.
  3. Brunner's glands are present in the submucosa of stomach and secrete pepsinogen.
  4. Goblet cells are present in the mucosa of intestine and secrete mucus.

Answer

(3) Brunner's glands are present in the submucosa of stomach and secrete pepsinogen.

Solution

As per NCERT, Brunner's glands are present in the submucosa of the duodenum, not the stomach; they secrete an alkaline mucous fluid, not pepsinogen.

Pepsinogen is secreted by the peptic (chief) cells of the gastric glands.

Statements (A), (B) and (D) are correct.

Answer: (3)
