HUMAN NUTRITION

Detailed explanation-1: -Pancreas secretes fluid rich in digestive enzymes and bicarbonate. The alkaline secretion is important in buffering of acid chyme entering duodenum and for activation of enzymes.

Detailed explanation-2: -The pancreas produces the enzyme-and bicarbonate-rich pancreatic juice and delivers it to the small intestine through ducts.

Detailed explanation-3: -The exocrine pancreatic duct is unique in its ability to secrete a fluid with bicarbonate concentrations as great as 140 mM [4–6]. The ductular epithelium and the centroacinar cell are enriched in the enzyme carbonic anhydrase which facilities the formation of bicarbonate from CO2 and H2O [102, 103].

Detailed explanation-4: -Pancreatic juice consists of an alkaline (chiefly bicarbonate) fluid and enzymes; 200–800 mL is produced each day. The enzymes, such as trypsin, lipase, and amylase, are essential for the digestion of most of the protein, fat, and carbohydrate in the meal.
