Glucagon is a peptide hormone, produced by alpha cells of the pancreas. It raises the concentration of glucose and fatty acids in the bloodstream and is considered to be the main catabolic hormone of the body. [1] It is also used as a medication to treat a number of health conditions.
In beta cells, insulin release is stimulated primarily by glucose present in the blood. [4] As circulating glucose levels rise such as after ingesting a meal, insulin is secreted in a dose-dependent fashion. [4] This system of release is commonly referred to as glucose-stimulated insulin secretion (GSIS). [10]
The release of these hormones into the blood is stimulated by the entry of the acidic chyme into the duodenum. Their coordinated action results in the secretion of a large volume of pancreatic juice, which is alkaline and enzyme-rich, into the duodenum. The pancreas also receives autonomic innervation.
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
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.
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).
Pancreas, ileum: Increases insulin secretion Glucagon-like peptide 2: Ileum, colon: Enterocyte-specific growth hormone Growth factors: Throughout the gut: Cell proliferation and differentiation Growth hormone-releasing factor: Small intestine: Unclear Leptin: Stomach: Appetite control Motilin: Throughout the gut: Increases gastric emptying and ...
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.
