The digestive system can respond to external stimuli, such as the sight or smell of food, and cause physiological changes before the food ever enters the body. This reflex is known as the cephalic phase of digestion.he endocrine system is affected largely by many internal and external stimuli. One internal stimulus that causes hormone release is blood pressure. Hypotension, or low blood pressure, is a large driving force for the release of vasopressin, a hormone which causes the retention of water in the kidneys.
The digestive hormones should not be confused with digestive enzymes. The hormones coordinate the digestive process by acting as a chemical messenger. The enzymes are a part of chemical digestion by acting as a catalyst to breakdown food within the gut. Since most digestion hormones play multiple roles, any deficiency or excess can have a profound impact on the digestive process as described in Digestive Problems.
