==Control of GIT Secretions==
==Control of GIT Secretions==
*
*Presence of food in the GIT is detected by open chemoreceptors
*Signals to the endocrine cells or via the ANS releases gastrointestinal peptide hormones
*These hormones act to promote secretion, provide negative feedback or affect motility
*Closed mechanoreceptors also act to alter secretions
*Conditioned (associative) and unconditiones responses act via the ANS
