what are the four main parts of the pancreas?
474452
The pancreas has four main parts: the head, neck, body, and tail. The widest part is the head, which is attached to the first part of the small intestine, known as the duodenum.

The small intestine, pancreas, and liver This causes the pancreas to release pancreatic amylase. This enzyme breaks down the chyme into dextrin and maltose. From there, the wall of the small intestine begins to make lactase, sucrase, and maltase.

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.

Islets of Langerhans are micro-organs located in the pancreas and composed of at least four types of endocrine cells. The α- and β-cells are the most abundant and also the most important in that they secrete hormones (glucagon and insulin, respectively) crucial for glucose homeostasis.

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 bulk of the pancreas is composed of “exocrine” cells that produce enzymes to help with the digestion of food. These exocrine cells release their enzymes into a series of progressively larger tubes (called ducts) that eventually join together to form the main pancreatic duct.

The abdomen contains all the digestive organs, including the stomach, small and large intestines, pancreas, liver, and gallbladder. These organs are held together loosely by connecting tissues (mesentery) that allow them to expand and to slide against each other. The abdomen also contains the kidneys and spleen.

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. It is spongy, about six to ten inches long, and is shaped like a flat pear or a fish extended horizontally across the abdomen.

Where is the Pancreas? By Marty Makary M.D., M.P.H. Located directly behind the stomach, the pancreas lies deep in the center of the abdomen. Its position corresponds to an area 3-6 inches above the “belly button”, straight back on the back wall of the abdominal cavity.

The pancreas is a brownish, flattened gland found in the tissue between the stomach and small intestine. The pancreas produces digestive enzymes that are sent to the intestine via small ducts (the pancreatic duct). The pancreas also secretes insulin, which is important in the regulation of glucose metabolism.

Stomach. The stomach has four major regions: the cardia, fundus, body, and pylorus.

Pancreatic islets, also called islets of Langerhans, are groups of cells in your pancreas. The pancreas is an organ that makes hormones to help your body break down and use food. Islets contain several types of cells, including beta cells that make the hormone insulin.

The end of this duct is connected to a similar duct that comes from the liver, which delivers bile to the duodenum. Around 95 percent of the pancreas is exocrine tissue. It produces pancreatic enzymes to aid digestion. A healthy pancreas makes about 2.2 pints (1 liter) of these enzymes every day.

The abdominal cavity contains the greater part of the digestive tract, the liver and pancreas, the spleen, the kidneys, and the adrenal glands located above the kidneys.

Pancreatic juice: It consists of three enzymes such as trypsinogen, amylase and lipase. These enzymes act best in an alkaline medium and hydrolyze the food.

The pancreas contains exocrine glands that produce enzymes important to digestion. These enzymes include trypsin and chymotrypsin to digest proteins; amylase for the digestion of carbohydrates; and lipase to break down fats.

The pancreas is both an exocrine organ and an endocrine organ. This chapter is devoted to the exocrine pancreas. The exocrine pancreas is responsible for secretion of digestive enzymes, ions and water into the duodenum of the gastrointestinal tract.
