Question

Pancreas secrete-
a. Digestive enzymes
b. Insulin
c. Glucagon
d. All of the above

Answer 1

Hint: The pancreas serves the exocrine as well as endocrine functions of the body which secretes digestive enzymes, insulin and glucagon.

Complete answer:
- The pancreas is the organ which is located in the upper left abdomen behind the stomach. It has an important role in converting the food we eat into the fuel of the body.

- It has two main functions: an endocrine function and an exocrine function. Almost 95% of pancreatic cells perform exocrine function. The remaining cells have endocrine function and are called as islets of langerhans.

Exocrine functions include:
- These produce the enzymes that are essential for digestion, which include trypsin chymotrypsin, amylases, lipases etc. When the food enters the stomach these juices are released into a system of ducts that joins to the main pancreatic duct.
- Another duct called the common bile duct originates in the liver and gallbladder and produces another important digestive juice called the bile juice.

Endocrine functions:
- The endocrine component of the pancreas consists of the islets cells (islets of Langerhans) that create and release important hormones directly into the bloodstream.
- Two of the main pancreatic hormones are:
Insulin-which acts to lower blood sugar, and
Glucagon- which acts to raise blood sugar.

So, correct option is All of the above

Note: For the proper functioning of our body each organ system is well coordinated with each other. No organ can perform its functions distinctively.
