Location of the Pancreas The pancreas is located behind the stomach in the upper left abdomen. The central section of the pancreas is called the neck or body. The thin end is called the tail and extends to the left side. Functions of the Pancreas A healthy pancreas produces the correct chemicals in the proper quantities, at the right times, to digest the foods we eat.
Exocrine Function: The pancreas contains exocrine glands that produce enzymes important to digestion. 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. Pancreatitis Pancreatitis is inflammation of the pancreas that occurs when pancreatic enzyme secretions build up and begin to digest the organ itself.
Precursors to Pancreatic Cancer The exact cause of pancreatic cancer is still unknown, but there are known risk factors that increase the risk of developing the disease. During digestion, your pancreas makes pancreatic juices called enzymes.
These enzymes break down sugars, fats, and starches. Your pancreas also helps your digestive system by making hormones. These are chemical messengers that travel through your blood. Pancreatic hormones help regulate your blood sugar levels and appetite, stimulate stomach acids, and tell your stomach when to empty. Your pancreas creates natural juices called pancreatic enzymes to break down foods. These juices travel through your pancreas via ducts.
They empty into the upper part of your small intestine called the duodenum. Each day, your pancreas makes about 8 ounces of digestive juice filled with enzymes. These are the different enzymes:.
This enzyme works together with bile, which your liver produces, to break down fat in your diet. If you don't have enough lipase, your body will have trouble absorbing fat and the important fat-soluble vitamins A, D, E, K. Symptoms of poor fat absorption include diarrhea and fatty bowel movements. This enzyme breaks down proteins in your diet. The main hormones secreted by the endocrine gland in the pancreas are insulin and glucagon, which regulate the level of glucose in the blood, and somatostatin, which prevents the release of insulin and glucagon.
Health Home Conditions and Diseases. The pancreas is made up of 2 types of glands: Exocrine. Functions of the pancreas The pancreas has digestive and hormonal functions: The enzymes secreted by the exocrine gland in the pancreas help break down carbohydrates, fats, proteins, and acids in the duodenum.
Glucose levels remain very stable in the blood at all times to ensure that the body has a steady supply of energy. This energy is needed for metabolism , exercise and, in particular, to fuel the parts of the brain that 'run' on glucose.
This makes sure that the body doesn't starve between meals. The most important hormone that the pancreas produces is insulin. Insulin is released by the 'beta cells' in the islets of Langerhans in response to food. Its role is to lower glucose levels in the bloodstream and promote the storage of glucose in fat, muscle, liver and other body tissues. This has the opposite effect to insulin, by helping release energy into the bloodstream from where it is stored, thus raising blood sugar levels.
Therefore, glucagon and insulin work in tandem to control the balance of glucose in the bloodstream. Other hormones produced by the pancreas include pancreatic polypeptide and somatostatin. They are believed to play a part in regulating and fine-tuning the insulin and glucagon-producing cells. Type 1 diabetes mellitus is caused when the body's immune system attacks its own cells in the islets of Langerhans, meaning that these cells cannot produce insulin.
Type 2 diabetes mellitus is a metabolic disorder where the body is no longer able to produce or respond to insulin. Some women also get diabetes temporarily when they are pregnant.
