For example, a buffer can be composed of dissolved HC 2 H 3 O 2 (a weak acid) and NaC 2 H 3 O 2 (the salt derived from that weak acid). Bicarbonate secretion by the duodenal mucosa is accepted as the primary important defense mechanism against the hydrochloric acid intermit- tently expelled from the stomach. How do secretin and cholecystokinin inhibit the stomach? Furthermore, What is the buffer in the duodenum?, In the human stomach and duodenum, the bicarbonate buffer system serves to both neutralize gastric acid and stabilize the intracellular pH of epithelial cells via the secretion of bicarbonate ion into the gastric mucosa. 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. All rights reserved.
