Document Summary
Non-git hormones may influence growth and development of the git. Git hormones may influence activities outside of the git. E. g. ghrelin is secreted by the endocrine cells of the stomach, but rarely acts in the git, it instead travels to the hypothalamic feeding centre to influence appetite. Leptin is secreted by adipose tissue, which acts on the brain to suppress appetite. At the same time, git hormones may play an important role in the regulation of the git itself. The diffuse endocrine system (des) is the largest and the most diversified endocrine system in the body. 5 of the most important gi hormones are gastrin, cck, secretin, gip and. 3 ways of endocrine regulation: autocrine (affect self). Released from the mucosa into the portal blood, which then goes to the liver, and via the circulation, reaches its target. They are capable of interacting with each other and the neurotransmitters.
