Secretory portion is composed of mucous tubules
Serous cells produce amylase
Serous acini are their main component
Serous acini produces IgA
Intercalated ducts belong to the interlobular ducts

The pancreas
The sublingual gland
The liver
The parotid gland
The submandibular gland
What is true about the exocrine part of the pancreas?
Serous cells of the pancreas produce digestive enzymes
Duct system includes striated ducts
The majority of enzymes are stored as proenzymes in secretory granules
Centroacinar cells constitute intra acinar portion of intercalated ducts
Contains spaces of Disse
Centroacinar cells may be found in the lumen of acini
Submandibular gland:
Formed by serous cells only
Mucous cells are its main component
Serous cells are the main component
There are no striated ducts
Centroacinar cells continues in the intra acinar portion of the intercalated duct
The pancreas develops from cells of:
