Stimulation of the duodenum by ingested foods leads to hormonal effects, which include:



A. A copious flow of pancreatic juice rich in bicarbonate

B. Decreased gastric motility

C. Contraction of the gall bladder and sphincter of Oddi

D. All of the above statements are correct

Answer :

Final answer:

The stimulation of the duodenum by ingested foods leads to several effects, including increased pancreatic secretion, decreased gastric motility, and gall bladder contraction. All these processes are essential for digestion. Thus, the correct answer is that all statements are correct.


Explanation:

Hormonal Effects of Duodenal Stimulation

The stimulation of the duodenum by ingested foods triggers several important hormonal responses that aid in digestion. The effects include:

  1. A copious flow of pancreatic juice rich in bicarbonate: This helps to neutralize gastric acid in the small intestine.
  2. Decreased gastric motility: This slows down the rate at which the stomach empties its contents into the duodenum, allowing for better digestion and absorption.
  3. Contraction of the gall bladder and sphincter of Oddi: This facilitates the release of bile, which is crucial for fat digestion.

Therefore, the correct answer is All of the above statements are correct, as each of these responses is vital for the digestive process.
