Understanding Your Pancreas
The pancreas is a glandular organ in the upper abdomen, but really it serves as two glands in one: a digestive exocrine gland and a hormone-producing endocrine gland. Functioning as an exocrine gland, the pancreas release enzymes to break down the proteins, . The pancreas gland works both as endocrine and exocrine gland, because it is a glanduar organ in the upper abdomen, but really it serves as two glands in one: a digestive exocrine gland and hormone - producing endocrine gland functioning as an exocrine gland, the pancreas excretes enzymes to breakdown the proteins, lipids, carbohydrates and nucleic food functioning as an endocrine gland, the .
When the pancreas secretes pancreatic juices into the duodenum of the digestive systemthose pancreatic enzymes are actually working outside of the human body. Technically the food that is being processed in the digestive tract is actually not yet part of the body until it is absorbed through the walls of the intestines and into the body tissues. We can think of the digestive tract as the hole of a donut. The empty space is actually not part of the donut.
Therefor the pancreatic enzymes in the intestine are exocrine in nature. When the pancreas secretes insulin from the Islets of Langerhans, the insulin is introduced into the functoons tissue and becomes and endocrine hormone. Liver: Exocrine function is secretion of bile through biliary tract. Kidney: Exocrine function is secretion of urine through the pelvis.
Endocrine function is the production and secretion of three hormones: Erythropoietin, Calcitriol and Renin technically an enzyme but functionally a hormone. Testis: Exocrine function is secretion of sperm through vas deferens. Endocrine function is production of testosterone. Ovary: Exocrine function is ovulation.
Endocrine function is production of estrogen and progesterone. What organ functions as both an endocrine and exocrine organ? Jun 1, The How to check video quality on skype acts as both an exocrine gland and an endocrine gland. Explanation: The Pancreas acts as exoceine an exocrine gland and an endocrine gland.
Samin Yasar. Sep 13, Pancreas is the common organ. There are some others like Liver, Kidney, and Gonads. Explanation: Liver: Exocrine function is secretion of bile through biliary tract. Endocrine function is to release IFG Insulin like Growth Factors that are edocrine for skeletal growth Kidney: Exocrine function is secretion of urine through the pelvis. Endocrine function is the production and secretion of three hormones: Erythropoietin, Calcitriol and Renin technically an enzyme but functionally a hormone Testis: Exocrine function is secretion of sperm through vas deferens.

Feb 26, · The pancreas is a gland that has both exocrine and endocrine functions. The exocrine portion of the pancreas secretes digestive enzymes, while the endocrine segment of the pancreas produces hormones. Pancreas Location and Anatomy The pancreas is elongated in shape and extends horizontally across the upper abdomen. The pancreas is both an endocrine and exocrine gland because it secretes both hormones and digestive enzymes. The pancreas the the main regulator of blood glucose levels. It produces insulin which decreases blood glucose levels and glucagon which increases blood glucose levels. This is . Pancreas functions both as an endicrine glands & exocrine glands. Endocrine glands in pancreas are made up of cell clusters & play an important role in glucose metabolism. Exocrine glands in pancreas support the digestive system through excreting digestive enzymes.
The pancreas is a soft, elongated organ located in the upper abdominal area of the body. It is a component of both the endocrine system and the digestive system. The pancreas is a gland that has both exocrine and endocrine functions. The exocrine portion of the pancreas secretes digestive enzymes, while the endocrine segment of the pancreas produces hormones.
The pancreas is elongated in shape and extends horizontally across the upper abdomen. It consists of a head, body, and tail region. The wider head region is located in the right side of the abdomen, nestled in the arc of the upper portion of the small intestine known as the duodenum.
The more slender body region of the pancreas extends behind the stomach. From the body of the pancreas, the organ extends to the tapered tail region located in the left side of the abdomen near the spleen. The pancreas is comprised of glandular tissue and a duct system that runs throughout the organ. The vast majority of glandular tissue is composed of exocrine cells called acinar cells. The acinar cells are assembled together to form clusters called acini. Acini produce digestive enzymes and secrete them into nearby ducts.
The ducts collect the enzyme containing pancreatic fluid and drain it into the main pancreatic duct. The pancreatic duct runs through the center of the pancreas and merges with the bile duct before emptying into the duodenum.
Only a very small percentage of pancreatic cells are endocrine cells. These small clusters of cells are called islets of Langerhans and they produce and secrete hormones. The islets are surrounded by blood vessels , which quickly transport the hormones into the bloodstream.
The pancreas has two main functions. The exocrine cells produce digestive enzymes to assist in digestion and the endocrine cells produce hormones to control metabolism. Pancreatic enzymes produced by acinar cells help to digest proteins , carbohydrates and fats. Some of these digestive enzymes include:.
The endocrine cells of the pancreas produce hormones that control certain metabolic functions, including blood sugar regulation and digestion. Some of the hormones produced by the islets of Langerhans cells include:. The production and release of pancreatic hormones and enzymes are regulated by the peripheral nervous system and gastrointestinal system hormones. Neurons of the peripheral nervous system either stimulate or inhibit the release of hormones and digestive enzymes based on environmental conditions.
For instance, when food is present in the stomach, peripheral system nerves send signals to the pancreas to increase the secretion of digestive enzymes.
These nerves also stimulate the pancreas to release insulin so that cells can take up the glucose obtained from the digested food.
The gastrointestinal system also secretes hormones that regulate the pancreas to aid in the digestive process. The hormone cholecystokinin CCK helps to elevate the concentration of digestive enzymes in pancreatic fluid, while secretin regulates the pH levels of partially digested food in the duodenum by causing the pancreas to secrete a digestive juice that is rich in bicarbonate. Due to its role in digestion and its function as an endocrine organ , damage to the pancreas can have serious consequences.
Common disorders of the pancreas include pancreatitis, diabetes, exocrine pancreatic insufficiency EPI , and pancreatic cancer. Pancreatitis is inflammation of the pancreas that can be acute sudden and short-lived or chronic long-lasting and occurring over time.
It occurs when digestive juices and enzymes damage the pancreas. The most common causes of pancreatitis are gallstones and alcohol abuse.
A pancreas that does not function properly can also lead to diabetes. Diabetes is a metabolic disorder that is characterized by persistent high blood sugar levels. In type 1 diabetes, insulin-producing pancreatic cells are damaged or destroyed resulting in insufficient insulin production. Without insulin, the cells of the body are not stimulated to take up glucose from the blood. Type 2 diabetes is initiated by the resistance of body cells to insulin. The cells are unable to utilize glucose and blood sugar levels remain high.
Exocrine pancreatic insufficiency EPI is a disorder that occurs when the pancreas does not produce enough digestive enzymes for proper digestion. EPI most commonly results from chronic pancreatitis. Pancreatic cancer results from the uncontrollable growth of pancreatic cells.
The vast majority of pancreatic cancer cells develop in areas of the pancreas that make digestive enzymes. Major risk factors for the development of pancreatic cancer include smoking , obesity, and diabetes. Share Flipboard Email. Regina Bailey. Biology Expert.
