where is insulin stored in the human body
Insulin Insulin is produced in the pancreas and the Brockmann body (in some fish), and released when any of several stimuli are detected. These stimuli include ingested protein and glucose in the blood produced from digested food.[43] Carbohydrates can be polymers of simple sugars or the simple sugars themselves. If the carbohydrates include glucose, then that glucose will be absorbed into the bloodstream and blood glucose level will begin to rise. In target cells, insulin initiates a signal transduction, which has the effect of increasing glucose uptake and storage. Finally, insulin is degraded, terminating the response.
Pancreas The pancreas is a secretory structure with an internal hormonal role (endocrine) and an external digestive role (exocrine). The endocrine part is composed of hormonal tissue distributed along the pancreas in discrete units called islets of Langerhans.[2] Islets of Langerhans have a well-established structure and form density routes through the exocrine tissue.[2] The exocrine part has two main ducts, the main pancreatic duct and the accessory pancreatic duct. These drain enzymes through the ampulla of Vater into the duodenum.[8]
