Etymology

Origin of pancreas

First recorded in 1570–80; from New Latin, from Greek pánkreas “sweetbread”; pan- + kréas “flesh, meat”

Explanation

The pancreas is part of the digestive system. It helps the stomach digest food. It’s a large, long gland that secretes insulin and digestive enzymes. Although the stomach gets the most of the credit for digesting food, it has a helper — the pancreas. The pancreas hides behind your stomach and helps digest and absorb nutrients, and it also helps you maintain a healthy blood sugar level by secreting insulin. This dual function makes the pancreas part endocrine (for the insulin) and part exocrine (for the digestive juices). These two functions make the pancreas important, but you can actually live without it.
