The intestinal hormone that stimulates the pancreas to release a watery, bicarbonate-rich fluid is<\/p>\n\n\n\n

A) enterocrinin.<\/p>\n\n\n\n

C) cholecystokinin.<\/p>\n\n\n\n

B) secretin.<\/p>\n\n\n\n

E) gastrin.<\/p>\n\n\n\n

D) GIP.<\/p>\n\n\n\n

The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is:<\/p>\n\n\n\n

B) Secretin<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Secretin is a crucial hormone in the digestive system that plays a significant role in regulating the pH of the small intestine. It is produced by the S cells<\/strong> located in the mucosa of the duodenum<\/strong>, which is the first part of the small intestine.<\/p>\n\n\n\n

Function of Secretin:<\/strong><\/h4>\n\n\n\n

When acidic chyme<\/strong> (partially digested food mixed with stomach acid) enters the duodenum from the stomach, secretin is released into the bloodstream. This hormone then stimulates the pancreas<\/strong> to release a bicarbonate-rich fluid<\/strong> into the small intestine. The bicarbonate neutralizes the stomach acid, creating a more alkaline environment. This is essential because:<\/p>\n\n\n\n

    \n
  1. Protects the intestinal lining<\/strong> \u2013 The stomach acid could damage the delicate lining of the small intestine if not neutralized.<\/li>\n\n\n\n
  2. Optimizes enzyme activity<\/strong> \u2013 Digestive enzymes from the pancreas function best in a neutral or slightly alkaline pH.<\/li>\n\n\n\n
  3. Prevents acid reflux into the duodenum<\/strong> \u2013 Secretin helps regulate gastric acid secretion by inhibiting the production of gastrin<\/strong>, a hormone that stimulates stomach acid release.<\/li>\n<\/ol>\n\n\n\n

    Comparison with Other Hormones in the Answer Choices:<\/strong><\/h4>\n\n\n\n
      \n
    • Enterocrinin (A):<\/strong> Stimulates intestinal glands to secrete digestive juices but does not affect the pancreas.<\/li>\n\n\n\n
    • Cholecystokinin (C):<\/strong> Stimulates the gallbladder to release bile and the pancreas to release digestive enzymes, but not bicarbonate.<\/li>\n\n\n\n
    • Gastrin (E):<\/strong> Stimulates gastric acid production in the stomach.<\/li>\n\n\n\n
    • Gastric Inhibitory Peptide (D) (GIP):<\/strong> Inhibits gastric motility and stimulates insulin secretion.<\/li>\n<\/ul>\n\n\n\n

      Thus, secretin<\/strong> is the primary hormone responsible for stimulating the pancreas to release a bicarbonate-rich fluid.<\/p>\n\n\n\n
