Pancreatic secretions accumulate in small ducts that drain to the main pancreatic duct that drains directly into the duodenum.

The free trypsin then cleaves the rest of the trypsinogen and chymotrypsinogen to their active forms. Once released in the intestine, the enzyme enterokinase, which is produced by the intestinal mucosa, activates trypsinogen by cleaving it to form trypsin. These zymogens are inactivated forms of trypsin and chymotrypsin. The two major proteases that the pancreas synthesizes are trypsinogen and chymotrypsinogen. The exocrine function of the pancreas is controlled by the hormones gastrin, cholecystokinin, and secretin, which are hormones secreted by cells in the stomach and duodenum in response to food. The pancreas also secretes bicarbonate ions from the ductal cells to neutralize the acidic chyme that the stomach churns out. The enzymes are activated once they reach the small intestine. The pancreas synthesizes its enzymes in the inactive form, known as zymogens, to avoid digesting itself. The pancreas is a dual-function gland, having features of both endocrine and exocrine glands. The cells are filled with secretory granules containing the inactivated digestive enzymes, mainly trypsinogen, chymotrypsinogen, pancreatic lipase, and amylase, that are secreted into the lumen of the acini. The pancreas is composed of pancreatic exocrine cells, whose ducts are arranged in clusters called acini. The exocrine function of the pancreas is essential for digestion as it produces many of the enzymes that break down the protein, carbohydrates, and fats in digestible foods. The pancreas functions as both an exocrine and endocrine gland. The pancreas is located posterior to the stomach and next to the duodenum. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme. As an endocrine gland, the pancreas produces several important hormones that include insulin, glucagon, somatostatin, and pancreatic polypeptide.ДЄs a digestive organ, the pancreas secretes pancreatic juice that contains digestive enzymes that assist the absorption of nutrients and digestion in the small intestine. The pancreas is a gland organ in the digestive and endocrine systems. pancreas: A gland near the stomach that secretes a fluid into the duodenum to help with food digestion.These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.

As a digestive organ, the pancreas secretes pancreatic juice that contains digestive enzymes that assist the absorption of nutrients and digestion in the small intestine.As an endocrine gland, the pancreas produces several important hormones that include insulin, glucagon, somatostatin, and pancreatic polypeptide.The pancreas is a gland organ in the digestive and endocrine systems.Thus, in short, we can say that the partially-hydrolysed proteins present in the chyme are acted upon by various proteolytic enzymes of the pancreatic juice for their complete digestion.
