The Function and Mechanics of the Digestive System Essay

Through this paper Let me explain the function and mechanics from the digestive system. The body’s technique of taking the food we eat and breaking it down to get hold of vital nutrients that will allow us to live and become healthy can be digestion.

Relating to “Wikipedia. com” (2013), “Digestion is a type of catabolism: a breakdown of enormous food molecules to smaller sized ones, is it doesn’t mechanical and chemical break down of food into smaller sized components which can be more easily soaked up into a blood stream” (Digestion). Digestion period varies between individuals and between males and females. After you take in, it takes regarding six to eight hours for meals to pass through your stomach and small is going to. Food after that enters your large intestinal tract (colon) for more digestion, compression of drinking water and, finally, elimination of undigested food (Picco, M. D., 2012).

The point when ever food enters the mouth, digestive function of the meals starts by the action of mastication, a type of mechanical digestive function where the teeth allow the chewing of food to aid inside the digestive procedure and the wetting contact of saliva (“Wikipedia. com”, 2013). Saliva, a liquid released by the salivary glands, is made up of salivary amylase, an enzyme which begins the digestion of starch in the foodstuff. After undergoing mastication and starch digestive function, the food will be in the form of a tiny, round slurry mass called a bolus.

It will eventually then travel around down the esophagus, the part of gastrointestinal tract that reaches from the goitre, and into the stomach, the organ inside the digestive tract that mixes foodstuff and secretes gastric juice, by the actions of peristalsis, this process could be 2 to 6 hours. Intestinal, digestive, gastrointestinal juice inside the stomach starts off protein digestion. Gastric juice mainly contains hydrochloric acidity and pepsin. As these two chemicals may damage the stomach wall membrane, mucus can be secreted by stomach, offering a slimy level that provides a shield up against the damaging effects of the chemicals. Although protein digestive function is occurring, mechanical mixing takes place by peristalsis, waves of muscular spasms that move along the belly wall.

This allows mass of food to increase mix with the digestive nzymes, typically several hours in human beings (“Wikipedia. com”, 2013). The resulting thick liquid is known as chyme. When the pyloric sphincter valve clears, chyme makes its way into the duodenum where it mixes with digestive enzymes from the pancreas, and then goes by through the little intestine, a tube formed organ from the digestive tract where digestion of ingested meals is completed and lots of of chemical absorption takes place and digestion continues coming from 3 to 5 hours.

When the chyme is completely digested, it can be absorbed in the blood. five per cent of consumption of nutrients occurs in the small intestinal tract. Water and minerals happen to be reabsorbed back into the blood inside the colon (large intestine) the place that the pH can be slightly acidic about five. 6 ~ 6. 9. Some vitamins, such as biotin and nutritional K (K2MK7) produced by bacteria in the intestines are also soaked up into the blood vessels in the bowel (“Wikipedia. com”, 2013). This procedure could take approximately 24 hours.

Garden waste is eliminated from the rectum during defecation through the anus, the lower beginning of the digestive tract through which the feces keep the body.
