In which part of the body would appendicitis occur?

Appendicitis occurs in the appendix, which is a small, tube-like structure attached to the large intestine. When the appendix becomes inflamed, it leads to the condition known as appendicitis. Symptoms commonly include abdominal pain, often starting near the navel and then shifting to the lower right abdomen, nausea, vomiting, and fever. Understanding this is essential because timely diagnosis and treatment, often involving surgical removal of the appendix, are crucial to prevent complications such as rupture.

The other options pertain to different organs that do not have any association with appendicitis. The gallbladder, liver, and spleen are distinct anatomical structures with separate functions in the body, making them unrelated to the occurrence of appendicitis.
