The pancreas is nestled below the stomach and behind the small intestines. It is 15 to 25 cm long and consists of regions called the head, body, and tail.
The pancreas produces insulin. This is why some diabetics receive pancreas transplants. It also produces less well-known hormones including glucagon and somatostatin, as well as enzymes that aid in digestion.

The pancreas is an elongated, tapered organ located across the back of the abdomen, behind the stomach. The right side of the organ (called the head) is the widest part of the organ and lies in the curve of the duodenum (the first section of the small intestine). The tapered left side extends slightly upward (called the body of the pancreas) and ends near the spleen (called the tail).
The pancreas is made up of two types of tissue:
-The exocrine tissue secretes digestive enzymes. These enzymes are secreted into a network of ducts that join the main pancreatic duct, which runs the length of the pancreas.
endocrine tissue
-The endocrine tissue, which consists of the islets of Langerhans, secretes hormones into the bloodstream.
Functions of the pancreas:
-The pancreas has digestive and hormonal functions:
-The enzymes secreted by the exocrine tissue in the pancreas help break down carbohydrates, fats, proteins, and acids in the duodenum. These enzymes travel down the pancreatic duct into the bile duct in an inactive form. When they enter the duodenum, they are activated. The exocrine tissue also secretes a bicarbonate to neutralize stomach acid in the duodenum.
-The hormones secreted by the endocrine tissue in the pancreas are insulin and glucagon (which regulate the level of glucose in the blood), and somatostatin (which prevents the release of the other two hormones).

Function of the Pancreas
The pancreas is a small organ located near the lower part of the stomach and the beginning of the small intestine. This organ has two main functions. It functions as an exocrine organ by producing digestive enzymes, and as an endocrine organ by producing hormones, with insulin being the most important hormone produced by the pancreas.
The pancreas secretes its digestive enzymes, through a system of ducts into the digestive tract, while it secretes its variety of hormones directly into the bloodstream.
Abnormal pancreatic function can lead to pancreatitis or diabetes mellitus.

Properties?
Hormones produced in the Islets of Langerhans are secreted directly into the blood flow by (at least) four different types of cells:
Beta cells producing Insulin and Amylin (65-80% of the islet cells)
Alpha cells releasing Glucagon (15-20%)
Delta cells producing Somatostatin (3-10%)
PP cells containing polypeptide (1%)
Produces the above stated and also pancreatic juice containing enzymes needed for digestion.

The pancreas is a gland organ in the digestive and endocrine systems (of vertebrates. It is both exocrine (secreting pancreatic juice containing digestive enzymes) and endocrine (producing several important hormones, including insulin, glucagon, and somatostatin).

The pancreas also produces digestive enzymes like proteases (breaks down proteins), lipases (breaks down fatty acids) and amylases (breaks down starch) plus other specialized digestive enzymes.
