Question

Quizplus · Accepted Answer

The duodenum is the first part of the small intestine and receives partially digested food from the stomach along with acidic gastric juice. This acidic fluid can cause damage to the lining of the duodenum and lead to the development of an ulcer. Other parts of the small intestine, such as the jejunum and ileum, are less likely to develop ulcers because they are not exposed to as much acidic fluid. The pylorus and cecum are not part of the small intestine and therefore not relevant to this question.
