The pancreas is located in the visceral region, and is a major part of the digestive system required for proper digestion and subsequent assimilation of macronutrient substances required for living. Pancreatic juice is alkaline in nature due to the high concentration of bicarbonate ions. Bicarbonate is useful in neutralizing the acidic gastric ...
Two ducts, the main pancreatic duct and a smaller accessory pancreatic duct run through the body of the pancreas. The main pancreatic duct joins with the common bile duct forming a small ballooning called the ampulla of Vater (hepatopancreatic ampulla). This ampulla is surrounded by a muscle, the sphincter of Oddi.
The mouth consists of two regions; the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks, [ 4 ] and the rest is the oral cavity proper. Most of the oral cavity is lined with oral mucosa , a mucous membrane that produces a lubricating mucus , of which only a small amount is needed.
Merocrine – the cells of the gland excrete their substances by exocytosis into a duct; for example, pancreatic acinar cells, eccrine sweat glands [dubious – discuss], salivary glands, goblet cells, intestinal glands, tear glands, etc. Apocrine – the apical portion of the cytoplasm in the cell membrane, which contains the excretion, buds off.
Chymotrypsin (EC 3.4.21.1, chymotrypsins A and B, alpha-chymar ophth, avazyme, chymar, chymotest, enzeon, quimar, quimotrase, alpha-chymar, alpha-chymotrypsin A, alpha-chymotrypsin) is a digestive enzyme component of pancreatic juice acting in the duodenum, where it performs proteolysis, the breakdown of proteins and polypeptides.

Trypsinogen (/ ˌ t r ɪ p ˈ s ɪ n ə dʒ ə n,-ˌ dʒ ɛ n / [1] [2]) is the precursor form (or zymogen) of trypsin, a digestive enzyme.It is produced by the pancreas and found in pancreatic juice, along with amylase, lipase, and chymotrypsinogen.
Pancreatic adenocarcinoma cells resemble pancreatic ductal cells. Both cell groups show tubule formation, cuboidal shape, and ductal markers. Additionally, acinar and endocrine cells have often been found in many of these cancers, demonstrating plasticity and the possibility that the initial target cells are pancreas progenitor cells.

The exocrine pancreas is one of two compartments that include digestive-acting acinar cells and duct cells.They represent an extension of the intercalated duct into each pancreatic acinus. [1] These cells are commonly known as duct cells , and secrete an aqueous bicarbonate solution under stimulation by the hormone secretin .
