Stomach, duodenum: Opiate-like actions Enteroglucagon: Small intestine, pancreas: Inhibits insulin secretion Galanin: Enteric nerves: Ghrelin: Stomach: Stimulates appetite, increases gastric emptying Glucagon-like peptide 1: Pancreas, ileum: Increases insulin secretion Glucagon-like peptide 2: Ileum, colon: Enterocyte-specific growth hormone ...
Insulin undergoes extensive posttranslational modification along the production pathway. Production and secretion are largely independent; prepared insulin is stored awaiting secretion. Both C-peptide and mature insulin are biologically active. Cell components and proteins in this image are not to scale.
Several hormones can affect insulin secretion. Estrogen is correlated with an increase of insulin secretion by depolarizing the β-cells membrane and enhancing the entry of Ca 2+. In contrast, growth hormone is known to lower the serum level of insulin by promoting the production of insulin-like growth factor-I (IGF-I).
This fluid is composed of four primary components: ions, digestive enzymes, mucus, and bile. About half of these fluids are secreted by the salivary glands, pancreas, and liver, which compose the accessory organs and glands of the digestive system. The rest of the fluid is secreted by the GI epithelial cells.
Heterocrine glands typically have a complex structure that enables them to produce and release different types of secretions. The two primary components of these glands are: Endocrine component: Heterocrine glands produce hormones, which are chemical messengers that travel through the bloodstream to target organs or tissues.

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.
