Stimulus (physiology) 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.

digestive system The main hormones that control digestion are gastrin, secretin, and cholecystokinin (CCK): 1  Gastrin causes the stomach to produce an acid for dissolving and digesting some foods. 2  Secretin causes the pancreas to send out a digestive juice that is rich in bicarbonate.

Nerves and the Digestive System Two types of nerves help control the action of the digestive system. Extrinsic nerves controlled by the brain cause muscle contractions that push food along the digestive tract.hey also cause the stomach and pancreas to produce more digestive juice. Intrinsic nerves within the walls of the esophagus, stomach, small intestine, and large intestine react when their walls are stretched by food.

- In addition, bowel disorders in the intestines can cause abdominal issues like stomach spasms. Irritable bowel syndrome serves as one such example. Changes in bowel habits — namely diarrhea or constipation — enlarge and irritate the intestinal tract, which in turn puts similar pressures on the connective stomach area.n addition, bowel disorders in the intestines can cause abdominal issues like stomach spasms.

Your Digestive System The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.our digestive system is uniquely designed to turn the food you eat into nutrients, which the body uses for energy, growth and cell repair. Here's how it works.

The Digestive System Stop 1: The Mouth. The mouth is the beginning of the digestive system, and, in fact, digestion starts here before you even take the first bite of a meal. The smell of food triggers the salivary glands in your mouth to secrete saliva, causing your mouth to water.When you actually taste the food, saliva increases.n addition, juices are produced that will help to further break down food. Chew your food more -- it helps with your digestion. Stop 2: The Pharynx and Esophagus. Also called the throat, the pharynx is the portion of the digestive tract that receives the food from your mouth.

The SNS is responsible for the Flight or Fight response of the body.When we get scared, the SNS increases our heart rate and provides energy to our muscles in preparation for action.he digestive system is under control of the Autonomic Nervous System (ANS).

- Another key digestive factor is that HCl is a stimulus to pancreatic secretions, containing the majority of enzymes that actively break down foods. The poor digestion of proteins, fats, and carbohydrates then further contributes to poor assimilation and nutritional problems. great many factors contribute to proper digestion, absorption, and utilization of the foods so needed to nourish our cells, tissues, and organs. The stomach, small intestine, liver, gallbladder, pancreas, and large intestine are primarily involved in the digestive process.

Digestive System The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).he six primary processes of the digestive system include: 1  Ingestion of food. 2  Secretion of fluids and digestive enzymes. 3  Mixing and movement of food and wastes through the body. 4  Digestion of food into smaller pieces. 5  Absorption of nutrients. 6  Excretion of wastes.
