Question

Identify the correct statement with reference to human digestive system.

• A. IIeum is a highly coiled part
• B. Vermiform appendix arises from duodenum
• C. Ileum opens into small intestine
• D. Serosa is the innermost layer of the alimentary canal

Answer 1

The correct option is A IIeum is a highly coiled part

All segments of the alimentary canal are divided into four layers: mucosa, submucosa, muscularis propria and the serosa. Serosa is the outermost layer of the alimentary canal.


Small intestine is divided into - duodenum, jejunum and ileum. Ileum is a highly coiled part of the small intestine and opens into large intestine.

Vermiform appendix arises from the caecum of the large intestine.

Thus, the correct answer is option a.
