What are main function of the secretin in monogastric digestion

Answer 1

1. Secretin stimulates the pancreas to release bicarbonate-rich fluid, which neutralizes the acidic chyme coming from the stomach. This helps create a more optimal pH environment for the digestive enzymes in the small intestine to function.

2. Secretin also stimulates the liver to produce bile, which is essential for the emulsification and breakdown of fats in the small intestine.

3. Secretin inhibits gastric acid secretion, helping to regulate the acidity levels in the stomach and prevent damage to the lining of the small intestine.

4. Secretin stimulates the release of enzymes from the pancreas that help break down carbohydrates, proteins, and fats into smaller molecules that can be absorbed and utilized by the body.
