Correct Option
The appendix is a small, finger-shaped, blind-ended tube projecting from the cecum, which is the beginning part of the large intestine. It is typically located in the lower right quadrant of the abdomen, near the ileocecal junction where the small intestine meets the large intestine. While historically considered a vestigial organ, current understanding suggests it may contribute to gut immunity and serve as a reservoir for beneficial gut flora.
Incorrect Options
Option 2: The appendix is not directly attached to the small intestine. It is situated at the junction where the small intestine (ileum) empties into the large intestine (cecum), specifically projecting from the cecum.
Option 3: The gall bladder is an organ of the biliary system, primarily responsible for storing and concentrating bile produced by the liver. It is anatomically and functionally distinct from the appendix and the large intestine.
Option 4: The stomach is located in the upper abdomen and is a primary organ of digestion. The appendix is situated in the lower right abdomen, making it anatomically distant and unrelated to the stomach.
