pancreas

Examples of pancreas in the following topics:

• Anatomy of the Pancreas

  • The pancreas lies in the epigastrium or upper central region of the abdomen and can vary in shape.
  • The pancreas lies in the epigastrium or upper central region of the abdomen.
  • The tail is the left end of the pancreas.
  • The pancreatic branches of the splenic artery also supply the neck, body, and tail of the pancreas.
  • 1: Head of pancreas 2: Uncinate process of pancreas 3: Pancreatic notch 4: Body of the pancreas 5: Anterior surface of the pancreas 6: Inferior surface of the pancreas 7: Superior margin of the pancreas 8: Anterior margin of the pancreas 9: Inferior margin of the pancreas 10: Omental tuber 11: Tail of the pancreas 12: Duodenum.

• Pancreas

  • The pancreas is a gland organ in the digestive and endocrine systems.
  • The pancreas is a gland organ in the digestive and endocrine systems.
  • The pancreas is located posterior to the stomach and next to the duodenum.
  • The pancreas functions as both an exocrine and endocrine gland.
  • The pancreas crosses above the left kidney.

• Histology of the Pancreas

  • The pancreas is a glandular organ in the digestive system and endocrine system of vertebrates.
  • Under a microscope, stained sections of the pancreas reveal two different types of parenchymal tissue.
  • These produce hormones that underlie the endocrine functions of the pancreas.
  • Acinar cells belong to the exocrine pancreas and secrete digestive enzymes into the gut via a system of ducts.
  • The pancreas is a dual-function gland that has the features of endocrine and exocrine glands.

• Associated Organs

  • The pancreas, liver, and gallbladder are the essential associated organs of the digestive system.
  • The pancreas, liver, and gallbladder are organs that are essential for digestion.
  • The pancreas is located posterior to the stomach and next to the duodenum.
  • The pancreas functions as both an exocrine and endocrine.
  • The two major proteases which the pancreas synthsizes are trypsinogen and chymotrypsinogen.

• Pancreatitis

  • Pancreatitis, or inflammation of the pancreas, occurs when the pancreatic enzymes that digest food are activated inside the pancreas.
  • Pancreatitis is inflammation of the pancreas.
  • Pancreatitis occurs when the pancreatic enzymes that digest food are activated in the pancreas instead of the small intestine, causing the pancreas to digest, or break down, its own tissue .
  • Severe pancreatitis has high mortality rates, especially where the pancreatic enzymes have begun to kill off parts of the pancreas, causing tissue necrosis.
  • The pancreas connects to the small intestine via the pancreatic duct.

• Types of Cells in the Pancreas

  • The islets of Langerhans are the regions of the pancreas that contain many hormone-producing endocrine cells.
  • The pancreas is a glandular organ that belongs to both the digestive and the endocrine systems of vertebrates.
  • Under a microscope, stained sections of the pancreas reveal two different types of parenchymal tissue.
  • Acinar cells belong to the exocrine pancreas and secrete digestive enzymes into the gut via a system of ducts.
  • Somatostatin is a hormone that suppresses the release of the other hormones made in the pancreas.

• Pancreatic Juice

  • The pancreas is a glandular organ in the digestive system and endocrine system of vertebrates.
  • Pancreatic juice is a liquid secreted by the pancreas that contains a variety of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases, and amylase.
  • Because the pancreas is a sort of storage depot for digestive enzymes, injury to the pancreas is potentially fatal.
  • A puncture of the pancreas generally requires prompt and experienced medical intervention.

• Overview of Pancreatic Islets

  • Pancreatic islets, also called the islets of Langerhans, are regions of the pancreas that contain its hormone-producing endocrine cells.
  • The pancreas serves two functions, endocrine and exocrine.
  • The pancreatic acini are clusters of cells that produce digestive enzymes and secretions and make up the bulk of the pancreas.
  • Somatostatin is a hormone that suppresses the release of the other hormones made in the pancreas.
  • The islets of Langerhans are the regions of the pancreas that contain its endocrine (hormone-producing) cells.

• Anatomy of the Liver

  • The hepatic artery carries blood from the aorta to the liver, whereas the portal vein carries blood containing the digested nutrients from the entire gastrointestinal tract, and also from the spleen and pancreas to the liver.
  • The spatial relationship between the liver, stomach, gall bladder, and pancreas.
  • The liver is seen above the stomach, gall bladder, and pancreas.

• Chemical Digestion of Carbohydrates, Proteins, Lipids, and Nucleic Acids

  • Protein digestion occurs in the stomach and the duodenum through the action of three primary enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.
  • Thus, trypsin is secreted by the pancreas in the form of trypsinogen, which is activated in the duodenum by enterokinase to form trypsin.
  • The presence of fat in the small intestine produces hormones that stimulate the release of pancreatic lipase from the pancreas, and bile from the liver, enabling the breakdown of fats into fatty acids.
  • DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase), which are released by the pancreas.
