Insulin is produced by the pancreas in a region called islets of Langerhans. In the islets of Langerhans, there are beta-cells, which are responsible for production and storage of insulin. Insulin is secreted as a response mechanism for counteracting the increasing excess amounts of glucose in the blood.
The infusion set is replaced regularly, usually every 2–3 days. Insulin absorption becomes less effective the longer the set is left in place, leading to poorer control of blood glucose. For this reason, the site of the infusion set is moved when the set is changed. Often a number of favorite sites for the infusion set are used on a rotation ...
This is because many of the principles of insulin dosage adjustment are remarkably similar in both type 1 and type 2 diabetes mellitus, and even without an endogenous insulin secretion model function, AIDA still can offer realistic simulations (from an educational perspective) for people with non-insulin dependent (type 2) diabetes mellitus ...
In many people, both a rapid- or short-acting insulin product as well as an intermediate- or long-acting product are used to decrease the amount of injections per day. In some, insulin injections may be combined with other injection therapy such as GLP-1 receptor agonists. Cleansing of the injection site and injection technique are required to ...
There are about 1 million islets distributed throughout the pancreas of a healthy adult human. While islets vary in size, the average diameter is about 0.2 mm. [5]:928 Each islet is separated from the surrounding pancreatic tissue by a thin, fibrous, connective tissue capsule which is continuous with the fibrous connective tissue that is interwoven throughout the rest of the pancreas.
Small lumps that form under the skin when a person keeps injecting a needle in the same spot. See also: Lipodystrophy; injection site rotation. Insulin pen An insulin injection device the size of a pen that includes a needle attached to a vial of insulin. It can be used instead of syringes for giving insulin injections. Insulin pump

The insulin receptor (IR) is a transmembrane receptor that is activated by insulin, IGF-I, IGF-II and belongs to the large class of receptor tyrosine kinase. [5] Metabolically, the insulin receptor plays a key role in the regulation of glucose homeostasis; a functional process that under degenerate conditions may result in a range of clinical manifestations including diabetes and cancer.
