Chapter 23: The Gastro System

2.

Most ulcers are found in the:

Ileum
Stomach
Liver

Correct Answer

A. Stomach

Explanation

Most ulcers are found in the stomach. This is because the stomach lining is constantly exposed to stomach acid and digestive enzymes, which can damage the protective layer of mucus that lines the stomach. When this protective layer is compromised, the acid and enzymes can irritate and erode the stomach lining, leading to the formation of ulcers. Ulcers can also occur in other parts of the digestive system, such as the duodenum, but the stomach is the most common location.
