Different hormones, neurotransmitters and reflexes are involved in the complicated process of feeding in animals. Secretions and motility of the gastrointestinal tract are stimulated and carefully regulated by numerous factors, including environmental stimuli and the presence of food in different parts of the gastrointestinal tract, which are detected by chemoreceptors.

[[Control of Feeding - Anatomy & Physiology#Control of GIT Secretions|Secretions]] and [[Control of Feeding - Anatomy & Physiology#Control of Motility|motility]] of the gastrointestinal tract are stimulated and carefully regulated by numerous factors, including environmental stimuli and the presence of food in different parts of the gastrointestinal tract, which is deteted by chemoreceptors and mechanical receptors. Motility is modified by both intrinsic and extrinsic nervous sytems.
When a harmful substance is ingested the body acts to eliminate it in different ways to prevent the animal becoming ill, for example, through vomiting or diarrhoea.
