The Lancet is giving Wu Miao water popular science.

The Lancet: "Gastric acid, which refers to the secretion of hydrochloric acid in gastric juice." The human stomach continuously secretes gastric acid. ”

Wu Miaoshui: "Continuous secretion? That's not going to fill up anytime soon. ”

The Lancet: "If there is secretion, there will be discharge, how can it be full?" Its basal excretion rate is about 10% of the maximum excretion rate and varies diurnally, peaking a few hours after falling asleep and lowest before waking up in the morning. When food enters the stomach, stomach acid is secreted. The pH value of the stomach is about 7.0~7.2 when emptying, and when the bolus enters the stomach, the pH value can drop to between 2~3. ”

Wu Miaoshui: "So to speak. Stomach acid is really good. ”

The Lancet: "Good things are good things, but nothing is absolute. Stomach acid is a double-edged sword. ”

Wu Miaoshui: "'Double-edged sword. 'Did he injure 1,000 enemies and injure 800 himself?' ”

The Lancet: "That's right. The double-edged sword refers to the fact that when it is secreted too little or lacking, it can cause indigestion such as bloating and diarrhea; Excessive secretion will invade the gastric and duodenal mucosa, and at the same time increase the ulcer-induced efficacy of pepsin, which will directly lead to ulcer formation, ulcer perforation, bleeding and other complications. Moreover, high gastric acid can affect the aggregation of platelets and the activity of clotting factors, making the blood not easy to clot, leading to bleeding and rebleeding. ”

Wu Miaoshui: "Usually I eat faster. I didn't feel any discomfort in my stomach, I just ate too much and was a little bloated. But it was digested all at once, and it seems that my stomach is quite good. ”

The Lancet: "When it comes to gastric juice, we have to say that the gastric mucosa, the two of them can say that one is a spear and the other is a shield." ”

Wu Miaoshui: "The spear and the shield are mixed together, isn't that a contradiction?" ”

The Lancet: "You're right, they've always been in 'self-contradiction', and Li has been attacking and defending. It depends on which one is better? But it's usually a tie. ”

Wu Miaoshui pretended to think: "Well, it turns out that they are joking." ”

The Lancet: "What do you think, it's a duel to the death." ”

Wu Miaoshui didn't understand: "How is it a duel of life and death?" Then why don't I usually feel that he is fighting and fighting? ”

The lancet half-jokingly pointed to Wu Miaoshui's stomach and said, "You can hear it when your kid's stomach is barking." ”

Wu Miaoshui: "Sister, my stomach did scream, but it was hungry, not a fight." ”

The Lancet: "Are you hungry?" ”

Wu Miaoshui: "I'm hungry." ”

The Lancet: "Maybe you can find the residue here, you can go and find it!" It's still okay to fill your little belly. ”

Wu Miaoshui: "Sister, you're making fun of me again." ”

The Lancet: "Then you can listen to me." ”

Wu Miaoshui: "I've written it down, so you can continue." ”

The lancet brushed his hair with his fingers: "Gastric mucosa: The mucosa on the inner surface of the gastric cavity is the gastric mucosa, which is the innermost layer of the stomach wall. The fresh gastric mucosa is pale pink. When the stomach is empty or semi-full, the gastric mucosa forms many wrinkled walls. There are about 4~5 longitudinal wrinkles in the small curvature of the stomach; The greater curvature of the stomach is mostly transverse or obliquely wrinkled; The wrinkled walls of other parts are irregularly shaped. The gastric mucosa is composed of three layers: epithelium, lamina propria, and muscularis mucosa. Usually, the various types of gastritis and ulcers we talk about are mainly lesions of the gastric mucosa. Gastric mucosal lesions are more common, especially inflammation, ulcers, mucosal prolapse, and cancer. That's it for you, do you understand? ”

Wu Miaoshui didn't say a word, just stared at the stomach wall, his expression frozen, and his face was hideous.

The lancet kicked it over, lightly touching the side of its shoe.

"What are you doing, boy? I've said it all in vain. Didn't you listen to a word? ”

Wu Miaoshui pointed to the lining of his stomach and said, "Sister, is he hungry when he leaves there?" There are so many folds. 1, 2, 3, 4, 5, 5 longitudinal wrinkles. ”

The Lancet also silently counted with Wu Miaoshui in his heart.

There are indeed 5 longitudinal wrinkles, and this organism, the monkey is indeed hungry. If it weren't for the old slippery head, the professor choked him and fainted, then this should be the time to eat, the stomach will move very much, and the food eaten will fall through the esophagus over the cardia into the stomach. It is possible to bury both of them alive. In that case, it mixes with the food, is pushed into the stomach acid, and melts.

Lancet was scared when he thought about it, and hurriedly told Wu Miaoshui to find a safe place to hide.

In the vast sea, there is not a lot of land, where is it safe? The two of them looked around for a long time, but they couldn't find a so-called safe place.

At the beginning of the experiment, the old slippery professor, they had already expected this situation, so the monkeys did not eat, and they were kept with potions, and they were raised with potions such as glucose. So there is not a trace of food residue in the monkey's stomach.

In this unaccompanied, vast sea, there is only such a short period of land in it, which is really desperate.

There must be a road before the car reaches the mountain, and the boat is naturally straight to the bridge.

A small boat appeared in the center of the ocean, and a person could be faintly seen shaking on the boat, as if he was paddling, and from time to time there was a beautiful ballad.

"Melodious rippling oars, like the sea is not the sea without borders, not an inch of grass grows barren land, and the joy of fish and water is no water. Pre-conditioned carp jumping over the dragon gate. ……”

The Lancet was fascinated by this beautiful poem and couldn't help but sing along: "...... It's so nice. ”

Wu Miaoshui: "Sister, what is he singing?" ”

The Lancet: "He is expressing his feelings, and he has a revenge in vain, but he is helpless in this place where there is no grass and no birds and no." hindered his direction. ”

Wu Miaoshui: "I see, should we stop him for a ride." ”

The Lancet: "Okay, I also want to see who this master is." ”

Wu Miaoshui shouted with her hands flying: "Rower, come over to me, we want to take a boat." ”

The Lancet scolded Wu Miaoshui for treating elegant people with such rude and uncultured language. Then he was taught how to call the boatman.

Wu Miaoshui learned the words handed over by the lancet, and shouted loudly again: "Boat man, may I ask if you can cross the river for us." ”

The whole family seemed to have heard Wu Miaoshui's call, and smashed it over this side at an accelerated pace.

From time to time to come to the shore.

Boatman: "Where did you two come from?" Where are you going? ”

The Lancet: "We want to find a village and a city to rest. I don't know if the manufacturer can cross our ride. ”

Boatman: "Yes, but I charge for it, and you need to pay for it." ”

The Lancet: "Okay, please hurry, let's have a ride!" ”

Boatman: "Two people need 20% energy. I don't know if you can have it. ”

The Lancet remembered the registration card given to him by the mayor of District 98.

Holding it in both hands, he respectfully handed it to the boatman.

"Is this okay?"

The boatman took the registration card, looked at it, and said, "Yes." As he spoke, he took out a box that was a little bigger than the card and placed the registration card on it. The name card suddenly disappeared, only to be revealed two seconds later, and the transaction was complete.
