Insulin signal transduction pathway is secreted after glucose enters the beta cell and that triggers several other processes in a chain reaction. While insulin is secreted by the pancreas to lower blood glucose levels, glucagon is secreted to raise blood glucose levels. This is why glucagon has been known for decades as a counter-regulatory hormone. When blood glucose levels are low, the pancreas secretes glucagon, which in turn causes the liver to convert stored glycogen polymers into glucose monomers, which is then released into the blood. This process is called glycogenolysis. Liver cells, or hepatocytes, have glucagon receptors which allow for glucagon to attach
Insulin pump being injected, or if the cannula becomes bent or kinked in the body, preventing delivery. Therefore, pump users typically monitor their blood sugars more frequently to evaluate the effectiveness of insulin delivery. Use of insulin pumps is increasing because of: In 1963 Dr. Arnold Kadish designed the first insulin pump to be worn as a backpack. A more wearable version was later devised by Dean Kamen in 1976. Kamen formed a company called "AutoSyringe" to market the product, which he sold to Baxter Health Care in 1981. The insulin pump was first endorsed in the United Kingdom in 2003, by
