How long does it take for the eaten food to get to the stomach and how long does the food stay in th

The gastrointestinal tract is the place where food is digested and absorbed, and the food eaten will pass through the esophagus and directly enter the stomach, causing myopia.

The food will flow into the stomach very quickly. However, food will generally stay in the stomach for about four hours, and after four hours of gastric peristalsis and digestion, it will enter the small intestine, and after the small intestine absorbs nutrients, it enters the large intestine for excretion.

The food eaten will soon reach the stomach, because the time the food is in the mouth is only chewed and ground and swallowed, and the food passes through the esophagus into the stomach, and the esophagus is equivalent to the passage of food, and the food does not stay in it until it reaches the stomach.

Eaten food is generally digested into the stomach after 2 to 4 hours, and it will not be completely absorbed after 6 hours, so gastric lavage is generally meaningless after 6 hours.

The food that is eaten quickly reaches the stomach. It's just chewing through the mouth, then through the esophagus and into the stomach.

The food you eat will be in the house in a while, and it will be in your stomach in less than a minute.

The food you eat can reach your stomach right away, but digest it for a few hours.

What you eat goes straight to the stomach, and there is no other way!

Basically, it will get to the stomach in a short time.

It depends on everyone's situation.

Different foods stay in the stomach for different lengths of time.

1. Different foods stay in the stomach for different digestion times, the liquid eaten only stays for 5 10 minutes, the sugary foods such as rice and pasta stay for about 1 hour, the protein stays for about 2 3 hours, and the fat stays for 4 5 hours.

2. Generally, 5 minutes after the food enters the stomach, part of the chyme is excreted into the duodenum. Different foods are emptied at different rates, which is related to the physical properties of the food and its composition.

3. Thin and fluid food is faster than thick or solid food; Chopped, small-grained foods empty faster than larger pieces; Isofhomy fluid is faster than non-isotonic fluids.

4. Among the three main foods, the emptying time of sugars is shorter than that of proteins, and the emptying time of fatty foods is the slower. For mixed foods, it usually takes 4-6 hours for the stomach to empty completely.

In a normal person, the stomach can be emptied in two to three hours.

Four hours under normal circumstances.

1. Grain: hours - 3 hours. Liquid or semi-liquid cereals (e.g., porridge) take less time to digest, and foods that have been fermented and have no added fats (e.g., steamed buns, bread without fat) are easier to digest.

They have the highest digestibility in the body and can reach 98 .

2. Protein: hours - 4 hours. Liquid protein foods such as milk and soy milk are easier to digest, while protein-rich meats such as beef and chicken take 4 hours or more to fully digest.

3. Fats: 2 hours - 4 hours. The digestibility of fats is related to their content of lower fatty acids and unsaturated fatty acids, and the higher the content of these fatty acids, the easier they are to digest. Therefore, vegetable oils are more digestible than animal oils.

Analysis: Food into the stomach, it takes four hours to be decomposed and digested by the stomach, and then the stomach transports the food to the small intestine, after further decomposition and absorption, the components needed by the body are absorbed, and the unwanted ones will be sent to the large intestine, which has to be discharged from the body through intestinal peristalsis, each person's physique is different, and the time of discharge is also different, basically it takes about 8 to 10 hours.

The digestion of food begins in the oral cavity, and the digestion of food in the oral cavity is mainly mechanical (food is ground), because the food stays in the oral cavity for a short time, so the digestion in the oral cavity does not play a big role.

After the food enters the stomach from the esophagus, it is subjected to the mechanical digestion of the gastric wall muscles and the chemical digestion of gastric juice, at this time, the protein in the food is initially decomposed by pepsin in the gastric juice (with the participation of gastric acid), and the gastric contents become a porridge-like chyme state, and a small amount is pushed to the duodenum through the pylorus many times. After the chyme enters the duodenum from the stomach, it begins digestion in the small intestine.

The small intestine is the main site of digestion and absorption. Food is chemically digested in the small intestine by pancreatic juice, bile and small intestinal fluid, as well as mechanical digestion by the small intestine, and various nutrients are gradually broken down into simple absorbable small molecules that are absorbed in the small intestine. As a result, after food passes through the small intestine, the digestion process is almost complete, leaving only the indigestible food residues, which enter the large intestine from the small intestine.

There is no digestion in the large intestine, and it only has a certain absorption function.

The length of time food stays in the stomach depends on the nature of the food. The liquid is highly fluid and usually takes only a few minutes. Foods containing sugars and powdered foods are also easy to digest.

Fat and protein foods will take a little more time. Usually a meal stays in the stomach for about five hours, and the previous physiological hygiene books said that water and other liquids can be emptied in 15 minutes, and the time for mixed food to stay in the stomach is about 4 to 5 hours
