what is the function of the pancreas and where is it located?

The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.

The endocrine portion of the pancreas controls the homeostasis of glucose in the bloodstream. Blood glucose levels must be maintained within certain limits so that there is a constant supply of glucose to feed the cells of the body but not so much that glucose can damage the kidneys and other organs.

The endocrine hormones are secreted by clusters of cells called pancreatic islets (or islets of Langerhans). As a digestive organ, the pancreas secretes many digestive enzymes and also bicarbonate, which helps to neutralize acidic chyme after it enters the duodenum.

The pancreatic duct, or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct), is a duct joining the pancreas to the common bile duct to supply pancreatic juice provided from the exocrine pancreas, which aids in digestion.

The liver has a wide range of functions, including detoxification and the production of bile to help with digestion. It also plays a large role in metabolism. The pancreas serves two roles. As an endocrine gland, it produces several important hormones, including insulin and glucagon.

Location of the Pancreas The pancreas is located behind the stomach in the upper left abdomen. It is surrounded by other organs including the small intestine, liver, and spleen.

The pancreas is solid (acinar tissues), and contains drainage tubes (the pancreatic ductal system). The pancreatic juices are made in the acinar tissues, and passed by secretion into the tubes (ducts) for transport into the duodenum. The exit hole into the duodenum is called the papilla of Vater.

function in digestive systems of animals other mammals, an alpha-amylase called ptyalin is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine.

The pancreas is one of the most important endocrine glands. It is responsible for the secretion of insulin, a hormone that regulates the amount of sugar in the blood.

In the digestive system, CF mainly affects the pancreas. The pancreas is an organ that puts out (secretes) certain substances. They help with digestion and control the body's blood sugar levels. The abnormality in CFTR makes the pancreas secretions become thick.

Bile is stored in the gallbladder until it is needed. The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways (called ducts) into the small intestine, where they help to break down food.
467537
Ninety percent of the pancreas is composed of acinar cells which secrete digestive enzymes such as trypsin, chymotrypsin, and amylase for digestion of food in the small intestine.

Endocrine Function: The endocrine component of the pancreas consists of islet cells (islets of Langerhans) that create and release important hormones directly into the bloodstream. Two of the main pancreatic hormones are insulin, which acts to lower blood sugar, and glucagon, which acts to raise blood sugar.

Acinar cells are the exocrine (exo=outward) cells of the pancreas that produce and transport enzymes that are passed into the duodenum where they assist in the digestion of food.

It is located inside your abdomen, just behind your stomach. It's about the size of your hand. During digestion, your pancreas makes pancreatic juices called enzymes. These enzymes break down sugars, fats, and starches.

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. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.

As in all vertebrates, the pancreas has two digestive functions. It is the source of: 1) exocrine secretion of digestive enzymes (proteases, lipases, and carbohydrases) into the intestine and 2) endocrine secretion of the hormones insulin and glucagon that act to lower and raise blood sugar.
