Miracle digestive: 10 Numbers that will surprise you

Up to nine meters distance sets every bite that we can swallow. On these nine meters, a lot has happened, just the visual and olfactory change to have a glimpse of the ingested food after their trip through the body has taken place, no Matter how appetizing the food originally looked, and smelled – at the end of the Eaten usually looks unappealing and has also lost in terms of flavor is significantly more attractive.

What happens in digestion, the knowledge, however, few so carefully. Clearly, kind of sugar, proteins, fatty acids, minerals, vitamins and trace elements from the food you eat in the body. But how? And where?

Station 1: the eyes and the nose, or the head phase

The digestive process starts even before the first bite. Just the idea, the sight and the smell of a delicious dish, place the brain in such a way in anticipation that it is equal to the digestive apparatus into the swing brings The mouth produces saliva, gastric acid production is stimulated, and the liver prepares to the exploitation of the forthcoming meal before. Head stage doctors call this first step of digestion.

Already in front of the food produced in the stomach 30 to 40 percent of the juice, for the processing of the meal required.

Station 2: The Mouth

The jaw is equipped with 28 teeth, with the addition of four wisdom teeth. The sharp incisors are used primarily for a Bite, the cheek teeth are responsible for grinding coarse pieces, fine porridge. Schluckbar the chyme through the saliva. This contains mucous substances, so-called Mucins, which the chyme is nice and soft and flutschig make.

In addition to the Mucins stuck in the saliva also digestive enzymes, the time of the exploitation of the food, begin by carbohydrates in the sugar to decompose. The sugar is then absorbed by the oral mucosa and into the blood and transported. That is to say: If carbohydrate-rich food to eat, increases the level of blood sugar while Chewing.

Up to 1.5 liters of saliva are the salivary glands every day.

Station 3: esophagus and stomach

Swallowing takes only about five seconds. Hard to believe that this entertaining process 20 muscles involved are. They ensure that the food from the mouth passes through the approximately 25-centimeter-long esophagus into the stomach, and – very important – also there remains.

Because the stomach gets the food with a very aggressive mixture of hydrochloric acid, mucus and digestive enzymes to do that in the sensitive esophagus nothing to search has.

The stomach, the acidic juice can’t hurt, because it is lined with a neutralizing layer of protection. The acid – meets in the stomach a very important purpose: it kills germs from. Meanwhile, break down the digestive enzymes dietary proteins and make them available to the body. The muscle layers in the wall of the stomach knead the porridge vigorously, so that he can mix well with the juice.

Between one and four hours of time taking the stomach for a meal. The shortest retention time have proteins remain water and carbs, a little longer, and the longest, the stomach fat needs a diet rich in shares.

If the stomach with his work is done, provides the stomach muscles to ensure that the food in portions in the intestine slides can a body, whose surface is as large as a tennis court.

Station 4: The Small Intestine

The inner wall of the small intestine is very wrinkled. Would it be smooth, you would never ever in the belly of a people fit: Overall, has the small intestine on its inside an approximately 200-square-metre surface.

This has its meaning. Because in the wall of the small intestine sit cells, which are responsible for it, the chyme as many nutrients as possible to escape. The more cells in the intestinal wall space, the more efficient the absorption of nutrients can take place.

The length of the small intestine is from person to person different. Typically, it measures between three and seven meters.

Station 5: The Large Intestine

The large intestine is only about 1.5 meters long, for there is here, in the last section of the intestine, significantly more lives than in the small intestine: researchers estimate that each person, on average, about 39 trillion bacteria of 400 different species in the large intestine contributes.

Since it is predominantly useful bacteria, that is no reason for concern, but pleasing. The tiny organisms are so nice to us in the digestion of so-called ballast substances to help.

Ballast substances are very healthy, among other things, because you saturate relative to their low calorie content very well. That we can gain from these plant fibers at all power, to whom we owe our intestinal bacteria. In contrast to our digestive enzymes can intestinal bacteria of plant cell walls crack and the bulky carbohydrates into short-chain fatty acids decompose, which the body can use.

Unfortunately, the bacteria do something else: they produce Gas. Whoever has a lot of fiber-rich foods such as legumes, or raw food to take, has, therefore, sometimes with flatulence to fight. Up to two litres of Gas escape from the intestine per day.

Less like the gut of liquid separates. The 0.5-to 1.5 litres of food, which are smuggled every day from the small intestine into the colon, remove the colon about a Liter of water. After the Thickening remains a maximum of 200 grams of feces is left – unless you have diarrhea.
