Understanding the Pancreas: Functions and Health

Understanding the Pancreas Functions and Health

The pancreas is a sizable gland with a shape reminiscent of a tadpole, located deep within the abdominal cavity. It is quite essential for the processes of digestion and the regulation of blood sugar levels in our body.

Diagnosing pancreatic disease can be challenging because of the organ’s positioning. However, there are actions you can take to lower your likelihood of experiencing these issues.

What is a Pancreas?

Detailed anatomy of the pancreas showing its location behind the stomach and near the duodenum.

The pancreas is a big gland located behind your stomach. It resides in the curve of your duodenum, which is the initial segment of your small intestine. Your pancreas functions as a dual organ. Your pancreas serves two primary roles, and it produces:

  1. Enzymes (amylase, lipase, trypsin) that assist in the digestive process which includes the breakdown of carbohydrates, proteins, and fats (exocrine system).
  2. Hormones (insulin, glucagon, somatostatin) to regulate the levels of sugar present in your blood (endocrine system).

What role does the pancreas play in our body?

The pancreas is an essential organ that keeps your body in balance and helps support other organs such as your heart, liver, and kidneys.

One of the primary functions of your pancreas is to assist in the digestive process and it is responsible for releasing hormones that help regulate blood sugar levels.

Help with the process of digestion

Your pancreas produces approximately 1-4 liters of enzyme-rich digestive juice daily to help you digest nutrient breakdown from consumed foods. The specific amount can change based on the quantity of food you consume.

Following a meal, it’s likely that you don’t give much thought to the process of digestion unless you experience discomfort or develop indigestion.

However, multiple organs collaborate to assist in the breakdown process. Let’s explore what happens when food enters your stomach:

The Digestive Process: A Step-by-Step Breakdown

  • Step 1: Pancreatic Juice Release: After eating, your pancreas releases digestive juice into small ducts that flow into your main pancreatic duct.
  • Step 2: Duct Connection: Your main pancreatic duct merges with the bile duct. This duct transports bile from your liver to the gallbladder.
  • Step 3: Bile Transport: Bile travels from your gallbladder to the duodenum (small intestine’s first section).
  • Step 4: Digestive Breakdown: Pancreatic juice and bile enter the duodenum to breakdown food into nutrients.

Pancreas Create Hormones

Pancreas hormone production process regulating blood sugar levels.

The pancreas produces important hormones, such as insulin and glucagon, which play a crucial role in regulating the sugar levels in your bloodstream.

When your blood sugar levels rise, your pancreas produces insulin to help bring them back down. When the blood sugar levels drop, your pancreas generates glucagon to help raise them back up.

Maintaining balanced blood sugar is essential for your body to function effectively, ensuring that vital organs such as your heart, liver, kidneys, and brain operate smoothly.

Anatomy of Pancreas

Location of Pancreas in Body

Your pancreas is located deep within your abdomen, positioned behind the stomach and in front of the spine. The spleen, gallbladder, and liver surround the pancreas.

Anatomy of Pancreas

Pancreas has various components, each fulfilling a distinct function.

  1. Head: The head of the pancreas is located on the right side of the abdomen, which measures about 2-3 centimeters adjacent to the small intestine.
  2. Body: The pancreas central portion measures about 10-12 centimeters long and it contains most of the pancreatic tissue.
  3. Tail: The pancreas’ tail is about 2-3 cm in diameter, and it extends to the left side of the abdomen, adjacent to the spleen.
  4. Pancreatic Duct: The pancreatic duct runs the full length of the pancreas.

How does the pancreas appear?

The pancreas is a glandular organ, that measures about 6-10 inches (15-25 cm) in length and is situated in the abdominal cavity.

Your pancreas has a unique shape that resembles a tadpole, featuring a thicker head and a thin tail. Its surface is uneven, resembling the texture of a corn cob.

The pancreas constitutes around 0.1-0.2% of total body mass, which is roughly the weight of a small banana.

Common Pancreatic Disorders and Symptoms

Symptoms and types of pancreatic disorders such as pancreatitis and pancreatic cancer.

The pancreas is tucked away in your body, but it can still face issues. These issues can go from short-term inflammation of the pancreas to lasting illnesses.

Which diseases and disorders can compromise the pancreas?

Your pancreas can be affected by various conditions and ailments that can influence its functionality, including:

  • Chronic pancreatitis is persistent inflammation. It occurs due to excessive alcohol consumption, which may lead to discomfort, digestive issues, and the onset of diabetes.
  • Pancreatic cancer is a serious condition, and it is hard to detect in the early stages. It can also spread to other organs before being noticed. Signs and symptoms of pancreatic cancer may include pain in the abdominal area or back, weight loss, and jaundice.
  • Pancreatic cysts are quite common among individuals. They are fluid-filled sacs that could potentially contain precancerous cells. Regular checks and tests, like endoscopic ultrasound and biopsy, are important to keep an eye on these cysts.
  • Type 1 diabetes occurs when the pancreas is unable to generate adequate insulin levels.
  • Type 2 diabetes happens when the body makes insulin but does not use it well.
  • Hypoglycemia (low blood sugar) happens when blood glucose levels drop under 70 mg/dL, which can pose risks to the brain and essential organs. It is typically associated with diabetes, yet it can also impact individuals who do not have the condition.
  • Hyperglycemia (high blood sugar) arises when blood sugar levels exceed 180 mg/dL, which can lead to harm to organs and tissues. This situation frequently arises in diabetes when there is an insufficient amount of insulin available. If left unaddressed, it may lead to significant complications such as diabetic ketoacidosis.

Symptoms of Pancreatic Disease
