To prevent a child from touching or sticking anything inside a plug-in, I would use guards to cover the holes.

Explanation: Well, Insulin and glucagon are the hormones that cause blood glucose (blood sugar) preserved in a narrow range. The pancreas serves as the central part of this process. Secreted by the pancreas are both insulin and glucagon. Determined by the production of insulin and glucagon, people can find out whether someone may have diabetes, hypoglycemia, low blood pressure, etc. Insulin or glucose can be prescribed to victims of those listed issues, so it's mostly used to balance out the level of glucagon and insulin to try to stop the problem.
