What is the predominant frequency of slow waves in the small intestine?
Understand the Problem
The question is asking for the predominant frequency of slow waves in the small intestine, which refers to the rhythmic contractions associated with the digestive processes in that area.
Answer
12 cpm in the duodenum, 9-11 cpm in the jejunum, and 8-10 cpm in the ileum.
The final answer is the predominant frequency of slow waves in the small intestine is approximately 12 cycles per minute (cpm) in the duodenum, 9-11 cpm in the jejunum, and 8-10 cpm in the ileum.
Answer for screen readers
The final answer is the predominant frequency of slow waves in the small intestine is approximately 12 cycles per minute (cpm) in the duodenum, 9-11 cpm in the jejunum, and 8-10 cpm in the ileum.
More Information
In the small intestine, there is a descending gradient of the slow wave frequency. This means that as you move from the duodenum to the ileum, the frequency of slow waves decreases.
Tips
A common mistake is to treat the small intestine as a single homogeneous section without acknowledging the frequency gradient present along its length.
