Imagine if the pancreas had to be pretty while releasing insulin.

It takes time for the islets to attach to new blood vessels and begin releasing insulin.

When glucose levels are elevated, the pancreas responds by releasing insulin.

Beta cells release insulin in response to rising levels of glucose.

When the level of blood glucose is high, the pancreas releases insulin into the bloodstream.

They inject calcium into the pancreas, which will cause the beta cells to release insulin.

When the body takes in sugar, the pancreas releases insulin to help blood glucose move into cells.

Conversely, when the blood-glucose levels are too high, the pancreas is signaled to release insulin.

Your body naturally releases insulin after you eat to keep your blood glucose at a certain level.

After some time, the islet cells attach to new blood vessels and begin releasing insulin.
