<unk> s are<unk>  (or semi-automated)<unk> s designed to assist people with diabetes, primarily type 1, by automatically adjusting insulin<unk>  to help them control their blood glucose levels. Currently available<unk> s (as of October 2020) can only<unk> (and regulate<unk>  of) a single hormone—insulin. Other<unk> s currently in development aim to improve on current<unk> s by adding one or more additional hormones that can be<unk> d as needed, providing something closer to the endocrine functionality of a healthy pancreas. The endocrine functionality of the pancreas is provided by islet cells which produce the hormones insulin and glucagon. Artificial pancreatic technology mimics the secretion of these hormones into the bloodstream in response to the body's changing blood glucose levels. Maintaining balanced blood sugar levels is crucial to the function of the brain, liver, and kidneys. Therefore, for type 1 patients, it is necessary that the levels be kept balanced when the body cannot produce insulin itself.<unk> s are often referred to using the term artificial pancreas, but the term has no precise, universally accepted definition. For uses other than<unk>  insulin<unk> , see Artificial pancreas (disambiguation).
