How long does it take for food to reach the stomach and intestines How long does food stay in the in

Food into the stomach, it takes four hours to be decomposed and digested by the stomach, and then the stomach transports 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 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, which is pushed to the duodenum through the pylorus many times in small quantities. 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 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.

It only takes a minute, but there's also the knowledge that you don't feel until 20 minutes later, that you're full. That's why you don't feel full when you first eat, and you feel uncomfortable a few minutes after you eat too much, because the stomach and intestines don't send this message to your cerebral cortex until 20 minutes after you eat.

Hope mine can make you increase your knowledge, good luck!!

Different foods stay in the stomach for different lengths of time. Under normal circumstances, dry and dilute mixed foods can stay in the stomach for 4-5 hours, while liquid foods feel full just after eating due to their large size, but stay in the stomach for a short time.

The time for food to stay in the stomach is about 1 hour for sugars, 2-3 hours for proteins, and 5-6 hours for fat.

It's useless, you're causing trouble with chronic enteritis, and it's useless if enteritis is good.

Anyone is different, your diarrhea may be half an hour after eating this kind of stuff and you start to have a reaction, so it can't be extrapolated from this.

I don't know much about this, but I will digest meat in five days, and vegetarian food in three days, I mean complete digestion.
