Is The Pancreas A Gland Or An Organ – The pancreas is located behind the stomach in the upper part of the abdomen, it is a glandular organ that has two basic “functions”. It is a digestive exocrine gland (secreting products through the tubes) and an endocrine gland secreting hormones (putting substances directly into the bloodstream). The pancreas produces enzymes to break down the food we eat, and produces insulin and glucagon to control blood sugar (Taylor 2018). The sponge, with a flat pear shape, is about 6-10 inches long (Columbia University Medical Center 2018). To better visualize its position, touch your right thumb with your right little finger, while holding the other three fingers straight and together. Place your hand in the middle of your stomach, just below the ribs, fingers pointing to the left. Your hand will approximate the shape and size of your pancreas (Johns Hopkins Medicine Pathology 2016).

It produces insulin and releases water that helps break down food. Problems with the pancreas can lead to diabetes, pancreatitis, and other health issues.
Pancreas: Functions And Disorders
The pancreas secretes enzymes, or digestive juices, into the small intestine. There, it continues to break down the food that has left the stomach. The pancreas also produces the hormone insulin and secretes it into the blood, where it controls the level of sugar or glucose in the body.
Problems with insulin regulation can lead to secondary diabetes, and inflammation of the pancreas can lead to pancreatitis. Benign and malignant tissue can also grow in the pancreas.
The largest part is on the right side of the stomach, where the stomach joins the first part of the small intestine, the duodenum. A narrow part of the pancreas extends to the left side of the abdomen near the spleen.
The duct runs the length of the pancreas and connects to the organ at several points. At its end, this duct joins the common bile duct that extends down from the liver. This joint releases bile into the duodenum.

About 95% of the pancreas is exocrine tissue. Exocrine tissues secrete substances into tissues and parts of the body other than the blood system.
. Endocrine tissues secrete substances into the blood. These clusters of grape cells produce important hormones that regulate pancreatic secretions and regulate blood sugar.
The exocrine tissues secrete a clear, watery, alkaline juice into the common bile duct and, ultimately, the duodenum. This substance contains several enzymes that break down food into small molecules. The intestine can then absorb these small molecules.
Endocrine tissue secretes insulin and other hormones into the blood. The beta cells of the pancreas release insulin when blood sugar levels rise.
Accessory Organs Of Digestion
Insulin moves sugar from the blood into muscles and other tissues for use as energy. Insulin also helps the liver absorb glucose, storing it as glycogen if the body needs energy during stress or exercise. When blood sugar drops, the alpha cells of the pancreas release the hormone glucagon.
Glucagon stimulates the breakdown of glycogen into glucose in the liver. Glucose then enters the blood, restoring blood sugar levels to normal.
If the pancreas does not produce enough digestive enzymes, for example, the digestive system will not absorb nutrients as intended. This can cause weight loss and diarrhea.
Inflammation can occur if gallstones or tumors block the main duct from the pancreas. Pancreatic juice will accumulate in the pancreas, causing damage. The pancreas may begin to digest itself.
Diabetes And Endocrine Function
Pancreatitis can occur as a result of mumps, gallstones, trauma, and the use of alcohol, steroids, and drugs.
Acute pancreatitis is a sudden, rapid inflammation of the organ. The condition is rare, but requires immediate treatment.
It is a progressive condition that can cause permanent damage. A person may experience pain, diarrhea, malnutrition, or diabetes. Treatment is aimed at controlling the pain to replace the lost enzymes.
Symptoms of pancreatic cancer may not appear until the cancer is in the advanced stages. By then, it may be too late for successful treatment. The outlook for pancreatic cancer tends to be poor. The 5-year survival rate is

For internal pancreatic cancer. This rate drops to 3% if the cancer is in other organs. The overall 5-year survival rate is 11%.
Type 1 diabetes is an autoimmune disease. It occurs when the immune system attacks and destroys the beta cells in the pancreas so that they can no longer produce insulin. The exact cause is still unknown, but it may be due to genetic and environmental factors, including viruses.
Glucose process adequately. This happens when the cells can’t use the insulin that the pancreas makes properly, or the pancreas can’t make enough insulin. As a result, the body can no longer control blood glucose levels.
The pancreas is a large gland that plays an important role in the digestive system. It produces enzymes that help break down food and release insulin, which is important in controlling blood sugar.
Can Body Repair Pancreas
Inflammation of the pancreas is called pancreatitis. This can cause pain, discomfort, and many health problems.
Avoiding smoking and excessive alcohol consumption and eating a balanced and healthy diet are the best ways to maintain a healthy pancreas.

In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, that is, it has docrine and exocrine digestive functions.
As an endocrine gland, it mainly works to control blood sugar levels, secreting the hormones insulin, glucagon, somatostatin and pancreatic polypeptide. As part of the digestive system, it functions as an exocrine gland that secretes pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which reduces acid tering duodum from the stomach; and digestive zymes, which break down carbohydrates, proteins and fats in food tering the duodum from the stomach.
Glands Of The Abdomen
Inflammation of the pancreas is known as pancreatitis, and common causes include chronic alcohol consumption and gallstones. Because of its role in blood sugar control, the pancreas is also an important organ in diabetes. Pancreatic cancer can occur following chronic pancreatitis or for other reasons, and carries a very poor prognosis, as it is often diagnosed only after it has spread to other parts of the body.
The word pancreas comes from the Greek πᾶν (pân, “all”) & κρεας (kréas, “body”). The function of the pancreas in diabetes has been known since at least 1889, and its role in insulin production was recognized in 1921.
The pancreas (shown here in pink) sits behind the stomach, with the body near the circumference of the duodenum, and the tail extending to touch the spleen.
The pancreas is an organ that in humans lies in the abdomen, stretching from the back of the stomach to the upper left abdomen near the spleen. In adults, it is about 12–15 centimeters (4.7–5.9 in) long, jointed and salmon-colored.
Pancreas Anatomy And Function
Anatomically, the pancreas is divided into the head, neck, body and tail. The pancreas extends from the inner fold of the duodenum, where the head surrounds two blood vessels: the superior mesenteric artery and vein. The longest part of the pancreas, the body, extends behind the stomach, and the tail of the pancreas is attached to the spleen.
Two ducts, the main pancreatic duct and the small accessory pancreatic duct run through the body of the pancreas. The main pancreatic duct joins the common bile duct to form a small balloon called the ampulla of Vater (hepatopancreatic ampulla). This ampulla is surrounded by a muscle, the sphincter of Oddi. This ampulla enters the descending part of the duodenum. The insertion of the common bile duct into the main pancreatic duct is controlled by Boyd’s sphincter. The pancreatic adduct enters the duodenum and separate shunts above the main pancreatic duct.
The head of the pancreas sits within the circumference of the duodum, and surrounds the superior mesenteric artery and vein. The right one resides in the descending part of the duodenum, and these betwe travel the superior and inferior pancreaticoduodal arteries. Behind sits the inferior va cava, and the common bile duct. In front sits the peritoneal membrane and the transverse colon.
A small uncinate process arises from the base of the head, located behind the superior mesenteric vein and sometimes the artery.
