Pancreas and insulin: An Overview - myDr.com.au

The pancreas is a thin, 15cm long organ that lies behind the stomach and under the liver. It is a vital organ with two crucial roles — helping the body digest food and making hormones that control blood sugar levels.
The pancreas has two main functions. Firstly, it helps the body break down, digest and absorb food. Secondly, it makes hormones that help control your blood sugar levels.
The pancreas is made up of glandular tissue and ducts (passages for body substances to flow through). These ducts help fluid from the pancreas flow into the duodenum (part of the small intestine).
The pancreas is made up of 2 types of cells.
Cells in your pancreas produce and release digestive enzymes into your duodenum, which is the start of the small intestine. In the duodenum, the digestive enzymes break down partially-digested food from the stomach.
A small part of the pancreas makes hormones that help control blood sugar levels. This part has alpha cells (which make glucagon) and beta cells (which make insulin). Glucagon and insulin work together to keep your blood glucose level steady.
