About those Langerhans...

The little patches in your pancreas. Is it “islands”, “islets” or “isles”? I’ve heard it all those ways.

Google gives you: islands: 109 100 - islets 279 000.

Wikipedia says Islets.

Islets. I used to transplant them.

Because it came up in pub trivia one night: Are they considered a separate organ from the pancreas, or just part of it?

Pancreas are divided in exocrine and endocrine parts. The endocrine part (ie, substances released within the vasculature with systemic effects) are the islets of Langerhans. The exocrine pancreas releases digestive enzymes to the duodenum via the pancreatic duct.
