Question

Does the pancreas secrete bicarbonate?

Answer 1

Pancreas

1. The pancreas is a compound (both exocrine and endocrine) elongated organ situated between the limbs of 'U' shaped duodenum.
2. Digestion enzymes and bicarbonate are two secretory products found in pancreatic juice that are essential for healthy digestion.
3. Bicarbonate is secreted by the epithelial cells lining the tiny pancreatic ducts, whereas the enzymes are produced and released by the exocrine acinar cells.
4. The pancreas secretes sodium bicarbonate to aid digestion.
5. This substance breaks down specific enzymes and assists in neutralizing stomach acid produced during digestion.
6. It protects the mucosal lining of the intestine by neutralizing acid.
7. It also maintains an alkaline pH, which is ideal for enzyme activity.
