Pancreas : structure of the pancreas in the human body


 What Is Pancreas?

The pancreas is a long, flat gland that sits tucked behind the stomach in the upper abdomen. It’s an important part of the digestive system and produces several enzymes that help the body break down and absorb food. The pancreas also produces the hormones insulin and glucagon, which help regulate blood sugar levels. Pancreas cancer occurs when cancerous cells form in the tissues of the pancreas.

What Is Pancreas

Your pancreas is a flat, pear-shaped gland about six inches long that's tucked behind your stomach in your upper abdomen. It has two main jobs: an exocrine function that involves secreting digestive enzymes into your small intestine to help you digest and absorb your food; and an endocrine function that involves secreting the hormones insulin and glucagon into the bloodstream to help regulate your blood sugar levels.  While the endocrine function is the one that's most often associated with diabetes — either type 1 diabetes, in which the pancreas doesn't produce enough insulin, or type 2 diabetes, in which the pancreas doesn't produce enough insulin or the body can't effectively use the insulin it produces — both types of.

The structure of the pancreas in the human body

The pancreas is a gland about 6 inches long that is shaped like a fish. The pancreas lies in the back of the abdomen, behind the stomach. The pancreas has several functions. It produces digestive juices that help to break down food in the small intestine.

The pancreas is an organ that in humans lies inside the abdomen, stretching from in the back of the stomach to the left higher stomach close to the spleen. In adults, its miles are approximately 12–15 centimeters (four.7–5.9 in) , lengthy, lobulated, and salmon-colored in appearance.


Anatomically, the pancreas is divided into a head, neck, frame, and tail. The pancreas stretches from the inner curvature of the duodenum, wherein the pinnacle surrounds  blood vessels: the advanced mesenteric artery and vein. The longest part of the pancreas, the body, stretches across in the back of the belly, and the tail of the pancreas ends adjoining to the spleen.


Two ducts, the principal pancreatic duct and a smaller accessory pancreatic duct run via the body of the pancreas. The important pancreatic duct joins with the not unusual bile duct forming a small ballooning referred to as the ampulla of Vater (hepatopancreatic ampulla). This ampulla is surrounded by a muscle, the sphincter of Oddi. This ampulla opens into the descending part of the duodenum. The beginning of the not unusual bile duct into the fundamental pancreatic duct is controlled by the sphincter of Boyden. The accent pancreatic duct opens into duodenum with separate openings placed above the outlet of the primary pancreatic duct.

The pancreas anatomy includes:

  • Head: The wider a part of the pancreas that sits within the curve of your duodenum.

  • Neck: The short part of the pancreas extending from the pinnacle.

  • Body: The center part of the pancreas between the pinnacle and neck, which extends upward.

  • Tail: The thinnest part of the pancreas, positioned near your spleen.

What is the role of the pancreas in the human body?

The pancreas is an organ in the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach. The pancreas is a mixed gland, having both an endocrine and an exocrine function. As an endocrine gland, it secretes hormones such as insulin, glucagon, somatostatin, and pancreatic polypeptide directly into the blood.

The pancreas performs  major features:

  • Exocrine characteristic: Produces materials (enzymes) that assist with digestion.

  • Endocrine characteristic: Sends out hormones that manage the amount of sugar in your bloodstream.

An exocrine gland runs the length of your pancreas. It produces enzymes that help to break down food (digestion). Your pancreas releases the following enzymes:

  • Lipase: Works with bile (a fluid produced by using the liver) to interrupt down fats.

  • Amylase: Breaks down carbohydrates for power.

  • Protease: Breaks down proteins.

When food enters your stomach:

  • Your pancreas releases the pancreatic enzymes into small ducts (tubes) that circulate the principal pancreatic duct.

  • Your important pancreatic duct connects together with your bile duct. This duct transports bile out of your liver in your gallbladder.

  • From the gallbladder, the bile travels to a part of your small gut called the duodenum.

  • Both the bile and the pancreatic enzymes enter your duodenum to break down food.

What affects the pancreas in the human body?

  • The pancreas is an organ located in the abdomen that produces a number of hormones including insulin, glucagon, and somatostatin. It also produces digestive enzymes that help to break down food in the small intestine. Pancreatic cancer is a type of cancer that affects the pancreas. It is a relatively rare form of cancer, but it is one of the most deadly forms of cancer.

  • The pancreas is a vital organ that is responsible for producing digestive juices and certain hormones, including insulin. It is located behind the lower part of the stomach. Problems with the pancreas can cause serious health problems. Pancreatitis is one such problem.

  • The pancreas is an organ located in the abdomen. It is responsible for producing digestive enzymes and hormones that help regulate blood sugar. Pancreatitis is a condition that occurs when the pancreas becomes inflamed. This can be a serious condition that can lead to death.

The following disorders can have an effect on the pancreas:

  • Type 1 diabetes: Type 1 diabetes happens whilst your pancreas doesn’t produce insulin.

  • Type 2 diabetes: Type 2 diabetes takes place when your body makes insulin but doesn’t use it efficiently.

  • Hyperglycemia: Hyperglycemia happens while your frame produces an excessive amount of glucagon. This affects high blood sugar degrees.

  • Hypoglycemia: Hypoglycemia happens whilst your frame produces an excessive amount of insulin. It causes low blood sugar levels.

  • Pancreatitis: Pancreatitis happens whilst enzymes start to paint inside the pancreas before they reach the duodenum. It may additionally result from gallstones or immoderate alcohol. Pancreatitis may be temporary or long-lasting (persistent).

  • Pancreatic most cancers: Cancerous cells within the pancreas cause pancreatic most cancers. Pancreatic most cancers may be hard to come across and deal with.

Maintaining the health of the pancreas in the human body

The pancreas is a large organ that’s located near the stomach. The pancreas is responsible for secreting digestive enzymes and insulin. When the pancreas fails, it can cause numerous health problems.

The pancreas is a vital organ in the human body that helps with the digestion of food. It is responsible for producing insulin and other hormones that help to control the blood sugar levels in the body. If the pancreas is not functioning properly, it can lead to a number of health problems. Improperly functioning pancreas can cause weight gain, diabetes, and even pancreatitis.

You can help reduce your hazard of pancreatic situations by way of:

  • Maintaining a healthy weight. Regular exercise and warding off weight benefit can help save you Type 2 diabetes and gallstones that can cause pancreatitis.

  • Eating a low-fats weight-reduction plan. High fat intake can cause gallstones, which can motivate pancreatitis. Being overweight is likewise a dangerous thing for pancreatic cancer.

  • Watching your alcohol consumption. Drinking alcohol can book your hazard of pancreatitis and pancreatic cancer.

  • Quitting smoking. Using tobacco, alongside cigar smoking and smokeless tobacco products, can boost your danger of pancreatic cancer and persistent pancreatitis.

  • Getting normal checkups. Seeing your healthcare company for regular exams can assist locate early signs and symptoms of conditions including pancreatic most cancers and pancreatitis.

Pancreas transplant

A pancreas transplant is a choice for a few humans with kind 1 diabetes. Type 1 diabetes is an autoimmune disorder wherein the pancreas stops producing the hormone insulin. The typical remedy for kind 1 diabetes entails everyday injections of insulin.

During a pancreas transplant, you’ll acquire a wholesome pancreas from a donor who has died. If you have got kidney failure out of your diabetes, your health care professional can also do a kidney transplant at the same time. The kidney transplant can be accomplished earlier or even after the pancreas transplant.
