The pancreas maintains constant blood glucose levels (shown as the waving line). When the blood glucose level is too high, the pancreas secretes insulin and when the level is too low, the pancreas secretes glucagon. Cells within the pancreas help to maintain blood glucose levels (homeostasis). The cells that do this are located within the ...
Beta cells (β-cells) are specialized endocrine cells located within the pancreatic islets of Langerhans responsible for the production and release of insulin and amylin. [1] Constituting ~50–70% of cells in human islets, beta cells play a vital role in maintaining blood glucose levels. [2] Problems with beta cells can lead to disorders such ...
The pancreas is involved in digestion and managing blood sugar. When it's is in trouble, diabetes, pancreatitis, or pancreatic cancer can result. How to care for this organ.
Enteroendocrine cells are specialized cells of the gastrointestinal tract and pancreas with endocrine function. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses.
If the blood glucose level falls to dangerously low levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a peptide hormone which travels through the blood to the liver, where it binds to glucagon receptors on the surface of liver cells and stimulates them to break down glycogen stored inside the cells into glucose (this ...

Pancreas contain nearly 1 to 2 million islets of Langerhans (a tissue which consists cells that secrete hormones) and acini. Acini secretes digestive enzymes. [9] Alpha cells. The alpha cells of the pancreas secrete hormones to maintain homeostatic blood sugar. Insulin is produced and excreted to lower blood sugar to normal levels.
Endocrine function: This involves the secretion of hormones directly into the bloodstream. Pancreas produces hormones such as insulin and glucagon, which help regulate blood sugar level. Insulin is released when blood sugar levels are high, and it promotes the uptake of glucose by cells, reducing blood sugar (hypoglycemia).
