Question

Which of the following digestive system structures releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic? a. Gallbladder b. Appendix c. Liver d. Pancreas

Answer 1

Answer:

d. Pancreas

Explanation:

The digestive system structure which releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic is called the pancreas. It makes use of the pancreatic duct in releasing the bicarbonates into the small intestine.

The bicarbonates aids the digestive processes and also neutralizes the duodenum from acidity. This is due to the the acidic food from the stomach and is as a result of the stomach being acidic and having acids such as dil. Hcl.

Answer 2

The system that breaks food molecules into smaller pieces and components for absorption and excretion is called the digestive system. It includes organs and secretions required for digesting liquids and food.

The digestive system that releases sodium bicarbonate is:

Option d. Pancreas

The system can be explained as:

• The pancreas is an organ that releases sodium bicarbonate and enzymes rich in pancreatic juices to send them to the small intestine through ducts.

• The acidic chyme produced in the stomach gets passed to the small intestine where the pancreatic secretion along with sodium bicarbonate buffers the acidic juices and inactivates the enzyme pepsin which changes the pH of chyme to basic.

• The bicarbonate salt neutralizes the acidic nature of chyme and protects the further digestive organs from acidic food.

Therefore, the pancreas secretes sodium bicarbonate.
