Question

Identify the correct statement with reference to the human digestive system.

Accepted Answer

Correct Answer: B — Ileum is a highly coiled partSolution:The ileum is the longest and most coiled part of the small intestine, occupying a large portion of the abdominal cavity. Its highly coiled nature increases the transit time of food, allowing maximum absorption of digested nutrients.Why other options are incorrect:A: The wall of the alimentary canal has four layers from inside out: Mucosa (innermost), Submucosa, Muscularis, and Serosa (outermost). Serosa is the outermost, not innermost layer.C: The vermiform appendix is a finger-like projection arising from the caecum (the first part of the large intestine), not from the duodenum.D: The ileum is the last part of the small intestine; it opens into the large intestine (specifically the caecum) at the ileocaecal junction, not into the small intestine.Key Concept: Layers of alimentary canal (inside to outside): Mucosa, Submucosa, Muscularis, Serosa. Ileum is the coiled last part of small intestine, opening into the caecum (large intestine). Vermiform appendix arises from the caecum.
