I do believe it i the pancreas :)
In the pancreas, the cells responsible for secreting bicarbonate (NaHCO3-) are the ductal cells. These cells line the pancreatic ducts and play a crucial role in neutralizing the acidic chyme that enters the small intestine from the stomach, creating an optimal environment for digestive enzymes to function. The bicarbonate is produced in response to hormonal signals, particularly secretin, which is released when acidic contents enter the duodenum.
The layer of the GI tract that functions by secreting a lubricating fluid is the mucosa. The mucosa layer is responsible for producing mucus, which acts as a lubricant to facilitate the movement of food through the digestive system. The mucus also protects the digestive organs from the effects of digestive enzymes and stomach acid.

Digestive system .
the endocrine system
The pancrease
The pancreas is part of the endocrine and digestive systems, secreting a number of enzymes.

Glandular tissue, a type of epithelial tissue, is responsible for producing and secreting chemicals and fluids. This tissue forms glands, which can be classified as endocrine glands (releasing hormones directly into the bloodstream) or exocrine glands (secreting substances through ducts to the surface of organs or tissues). Examples of secretions include sweat, saliva, and digestive enzymes.
