Question

The pancreatic gland secretes its exocrine secretion into
A. Duodenum
B. Large intestine
C. Spleen
D. Jejunum

Answer 1

The pancreas is a gland organ within the digestive and endocrine systems. As a secretor, it produces several hormones such as insulin, glucagon, somatostatin, and pancreatic polypeptide. The pancreas secretes digestive fluid that contains digestive enzymes that assist the absorption of nutrients and digestion within the intestine. These enzymes help to further break down the carbohydrates, proteins, and lipids within the chime.

Step by step answer: The pancreas is found posterior to the stomach and next to the duodenum. The pancreas functions as both an exocrine and endocrine. The exocrine function of the pancreas is important for digestion because it produces many of the enzymes that break down the protein, carbohydrates, and fats in digestible foods. The pancreas consists of pancreatic exocrine cells, whose ducts are arranged in clusters called acini. The pancreas may be a dual-function gland, having features of both endocrine and exocrine glands.
-Exocrine Function: Pancreas synthesizes its enzymes within the inactive form, referred to as zymogens, to avoid digesting itself. Enzymes are activated when they reach the small intestine. They also secrete bicarbonate ions from the ductal cells to neutralize the acidic chyme that the stomach churns out. This function of the pancreas is controlled by the hormones gastrin, cholecystokinin, and secretin, which are hormones secreted by cells within the stomach and duodenum in response to food. Once released within the intestine, the enzyme enterokinase, which is produced by the intestinal mucosa, activates trypsinogen by cleaving it to create trypsin. The free trypsin then cleaves the remaining trypsinogen and chymotrypsinogen to their active forms. Pancreatic secretions accumulate in small ducts that drain to the most channel that drains directly into the duodenum.
-Endocrine Function: The part of the pancreas with endocrine function is created by cell clusters called the islets of Langerhans. Four main cell types exist within the islets. The Islets of Langerhans are a collection of endocrine cells arranged in clusters and cords crisscrossed by a dense network of capillaries. The capillaries of the islets are lined by layers of endocrine cells that are in direct contact with blood vessels, either by cytoplasmic processes or by direct apposition.
Therefore, the correct option is A duodenum

Note: An inflammation of the pancreas is understood as pancreatitis. Pancreatitis is often diagnosed by the detection of pancreatic amylase and lipase in an exceeding biopsy. Patients may complain of pale stools and dark urine. In pancreatitis, the digestive enzymes of the pancreas damage the tissue and structure of the pancreas. The digestive enzymes don't reach the duodenum, resulting in incomplete digestion of fatty acids. This ends up in fatty stools (steatorrhoea), which have a pungent smell and float in water.
