Dietary fibre passes through several structures after leaving the stomach. In which order does the dietary fibre pass through the structures?
Correct answer: E. duodenum -> jejunum -> ileum -> colon -> rectum
- A. duodenum -> jejunum -> ileum -> rectum -> colon
- B. ileum -> duodenum -> colon -> jejunum -> rectum
- C. ileum -> duodenum -> jejunum -> rectum -> colon
- D. colon -> duodenum -> ileum -> rectum -> jejunum
- E. duodenum -> jejunum -> ileum -> colon -> rectum
Explanation
After leaving the stomach, the food enters the small intestine through a pyloric sphincter. The first region of the small intestine is the duodenum, the second is the jejunum, and the third is the ileum. The junction between the ileum and the large intestine is called the ileocecal junction. The caecum is the proximal end of the small intestine with a vermiform appendix attached to it. Then comes the colon, which has four parts and then the rectum. The last part of the large intestine is the anus. Thus, the order given in option E is correct.
