Which organ is a small, tube-like structure attached to the first part of the large intestine?

• A. Appendix
• B. Pancreas
• C. Cirrhosis
• D. Gallstones

Answer: (A)

Identifying the tube-like structure attached to the first part of the large intestine. That structure is the appendix, a narrow pouch that extends from the cecum, which is the beginning section of the large intestine right after the ileum. It's typically a few centimeters long and can become inflamed in appendicitis. The pancreas sits behind the stomach and connects to the small intestine, not attached to the cecum. Cirrhosis is scarring of the liver, not a tube-like structure. Gallstones form in the gallbladder or bile ducts, not as a tubular extension of the large intestine. So the tube-like structure in that location is the appendix.
