Explain the regulation of pancreatic juice and bile secretion. High protein meals thus stimulate much acid secretion by the gastric mucosa and also buffer the acid secreted. 1 Approved Answer. In conclusion, we could demonstrate that the duodenal bulb has a large buffering effect, thus counteracting the large amount of gastric acid passing into the small bowel after duodenal switch. The buffering effect is when the stomach acid is met with bicarbonate to reach a stable pH so that the cyme can be digested by the small intestine. Percentage of time with pH<4 was 70.0 (19.992.0) and 13.0 (0.034.6) pre and postpylorically, demonstrating a large buffering effect. government site. 7th August 2018.
