What makes acidic, partially digested food from the stomach turn alkaline in the small intestine? a) Bile juice secreted by the liver b) Pancreatic juice secreted by the pancreas c) Bicarbonate ions secreted by the wall of the esophagus d) Intestinal juice (succus entericus) secreted by the jejunum and ileum
Food being digested in the stomach is in a highly acidic environment. The pH of the small intestine is higher than that of the stomach. Which statement best explains why this occurs? Secretin increases the flow of bicarbonate ions from the pancreas into the small intestine to neutralize the stomach acid. When pepsinogen activates pepsin, one result is the neutralization of stomach acid in the stomach. Trypsinogen is activated, thus neutralizing the stomach acid. Bile salts from the gallbladder neutralize the stomach acid.
The digestive enzymes of the small intestine $a .$ do not function best at a low pH. $b$. are produced and released in response to circulating secretin. $c .$ are produced and released under neural control. $d$. are all secreted by the pancreas. $e .$ are all activated by an acidic environment.
