Which eukaryotic organelle is responsible for holding the coils of the small intestine together?

• A. Golgi apparatus
• B. Mesentery
• C. Mitochondrion
• D. Nucleus

Answer: (B)

Verified step by step guidance

1. Understand the question: The problem is asking which structure in the body holds the coils of the small intestine together. This is a structural and anatomical question rather than one related to cellular organelles.
2. Clarify the options: The Golgi apparatus, mitochondrion, and nucleus are cellular organelles found within eukaryotic cells. These organelles perform specific functions within the cell, but they are not involved in holding the small intestine together.
3. Introduce the correct concept: The mesentery is a fold of tissue (specifically, a double layer of peritoneum) that attaches the small intestine to the posterior abdominal wall. It provides structural support and contains blood vessels, nerves, and lymphatics that supply the intestines.
4. Explain why the mesentery is the correct answer: The mesentery's role is to stabilize the position of the intestines and prevent them from tangling while allowing movement during digestion. Cellular organelles like the Golgi apparatus, mitochondrion, and nucleus are unrelated to this anatomical function.
5. Conclude with a key takeaway: The mesentery is an anatomical structure, not a cellular organelle, and is responsible for holding the coils of the small intestine together. This highlights the importance of distinguishing between cellular and anatomical structures in physiology.
