The posterior abdominal wall at the level of 1 to 2 lumbar vertebral bodies.

The pancreas is a long, narrow gland placed transversely on the posterior abdominal wall at the level of 1 to 2 lumbar vertebrae and is soft and grayish-red in color. The pancreas can be divided into four parts: pancreatic head, pancreatic neck, pancreatic body, and pancreatic tail.

The pancreatic duct is located in the parenchyma of the pancreas, and its walk is consistent with the long axis of the pancreas, from the tail of the pancreas through the body of the pancreas toward the head of the pancreas, along the way to receive many interlobular ducts, and finally in the descending portion of the duodenum within the wall of the choledochal duct and the common bile duct into the hepatic-pancreatic pot-bellied, opening in the duodenal large papillae. A small duct is sometimes seen in the upper part of the head of the pancreas, traveling above the pancreatic duct, called the parapancreatic duct, which opens into the small duodenal papilla.

Extended information:

The pancreas secretes pancreatic juices that contain a variety of digestive enzymes, and it also secretes insulin, which regulates blood sugar. Acute pancreatitis is a common pancreatic disease, in addition, the incidence of pancreatic cancer is increasing in China.

It is recommended that people over the age of 40 and those with a history of diabetes and pancreatitis should go to the hospital for a checkup at least once a year; and they should seek medical attention right away if they have symptoms such as abdominal discomfort or pain in the upper and middle parts of the abdomen, jaundice, back pain, and splenomegaly.

The most important thing you can do to protect your pancreas is to avoid overeating, eat no or less greasy food, and drink less alcohol. Preventing the "three highs" (hyperlipidemia, hypercalcemia and hyperglycemia) can also reduce the risk of pancreatic disease.
