==The Physiology of feeding==

Different hormones, neurotransmitters and reflexes are involved in the complicated [[Control of Feeding - Anatomy & Physiology|process of feeding]] in animals. [[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, and reflexes prevent food from accidentally passing into the trachea during [[Deglutition|deglutition]], or swallowing.

When a harmful substance is ingested the body acts to eliminate it in different ways to prevent the animal becoming ill, for example, through [[Control of Feeding - Anatomy & Physiology#The Vomit Reflex|vomiting]] or diarrhoea. If one or more of the [[Control of Feeding - Anatomy & Physiology#Neuroendocrine Regulation of Feeding|neuroendocrine pathways]] involved with the control of feeding is damaged or inhibited, then problems such as obesity can occur.
