Mediterranean Hegemon of Ancient Greece

With this in mind, Dionia is the place that Greek doctors yearn for.

Davers opened the outer skin of the model's jaw and neck, revealing the passage inside: "Let's see, the passage of the mouth and nose is combined here, and then divided into two channels -"

He pointed to the hose made of nitrated leather: "We all know that the nose is used to breathe the air, but the mouth not only breathes the air, but also eats and drinks water. The air and the food go through the passages. After long-term observation by doctors in the medical school, they thought that the pipeline was taking air and calling it the trachea. In another passage behind him, through food and water, we called it the esophagus. Everyone touched themselves. Below the neck, the harder underside of the skin is not smooth, the trachea.

The Gentile doctor under the pulpit really touched his neck with his hands and realized the trachea that Devers said.

“Someone may ask if the openings of the esophagus and the trachea are connected together, isn't food and leeches easy to get into the trachea?” Davers said, seeing many people nodding, and laughing: “Facts This is almost impossible. There is a soft bone at the opening of the trachea. When we swallow, it will automatically cover the tracheal opening, so that food and water will not enter the trachea. If you have Interests, when the meeting is over, you can take a look at it. Our humanoid model made by our doctors under the guidance of a doctor is very accurate. However, you can not break it, but this model is The treasure of the town of the medical school, how much can't be bought? I am right, Hampus."

"Yes, Teacher Daves. We usually only use it when we are teaching. It is generally not going to touch people." Herpps smiled.

According to Davers and Hells, the Gentile doctors were so upset that they stood up and looked at the human body model beside Daves. The scene was a bit messy.

Davers continued to ask: "I heard that the young doctor of the school of cartilage found this cartilage. For this reason, he also specialized in dissecting live pigs and sheep, and carefully observed the movement of this cartilage. And mechanism, right?"

"Yes." Herpps nodded.

"Have he been here today?" Daphus asked with a smile.

"coming."

"So, ask Dr. Krytos to stand up and let everyone know." Daphus smiled and said loudly.

Under the push of his colleagues, Kritos stood up.

"Let us thank Kratos for this important discovery with warm applause!" Daves first applauded, and then the audience applauded warmly, and his classmates even whistled with excitement.

Kritos is nervous and excited.

Lycausus looked enviously at Kritos standing in front: this doctor who seems to be a little different from his age is shyly accepting the applause of the audience, and when he can be as famous as he is, he is Isn't it always an apprentice like a slave?

"Kritos, I look forward to your more medical discoveries and greater achievements!" Daves enthusiastically encouraged him.

It is ridiculous that a young man encourages another young person with the tone of his elders, but most doctors present do not think so. And Kritos is even more excited and ups and downs: "Good... good, Daves teacher!"

When Christos sat down, Davers continued: "If you sometimes eat something not seriously, you will suddenly have a cough. This is actually the cartilage covering the trachea is not timely, causing food to enter the trachea; if a mother holds The baby is looking for you to see a doctor and tells you, 'The child coughs when drinking milk,' but it may be because of this reason..."

What Davers said was to let the Gentile doctors remember it and confirm the similar cases he had seen before.

"The air goes into the organ along the trachea. The Dionysian medical school has dissected it many times and called this trachea a lung." Davers said, opening the chest of the mannequin and disassembling the left lung carved with wood. Show it to everyone.

"The result of the medical school's solution shows that there is a lung on each side of our body. It is like a pig's urine bubble. When the air enters, the lungs will expand; when exhaled, the air will expel. The lungs will shrink. You may be surprised that the air enters the lungs from the mouth and nose, and then exhales from the lungs. It seems that there is no point in turning back to the origin. But I tell you, we The body is the most precious treasure that the gods have given to the world. It is very wonderful and never makes meaningless things!"

The doctors under the Daves look around, seeing that they are all listening to it, and seriously said: "The medical school has repeatedly dissected the body and found that after the trachea enters the lungs, it continuously draws down the thinner pipes. Like a branch of a big tree with branches, how big is the trachea we can see?"

Davers pulled a hair from his head and said, "It's just that big! And what is the end of such a small trachea? Can anyone tell me?!"

At this time, a young Diaonia doctor stood up: "It's a blood vessel! We found that there are many tiny blood vessels that are intertwined with these airways. These tiny blood vessels have two large blood vessels from the heart. Constantly differentiated..."

"So, what is the use of these two large blood vessels from the heart?" Davers continued.

"They come from different parts of the heart, one is responsible for pumping blood into the lungs and the other is responsible for collecting blood from the lungs."

“What else is the difference?”

"Well... the blood pumping out is a blood vessel, and the blood is coming back with two blood vessels..." the young doctor hesitated and replied.

"This is different, is there?"

"Oh..." The young doctor blushes and can't answer.

"Thank you for your answer, what is your name?"

"Strobus of the University of Dionynia."

"Thank you for your wonderful answer, you said it is very good!"

Strobs, who was slightly frustrated, heard Davis's compliment and smiled.

"You, the air turned around in the lungs and went out, the blood turned around in the lungs, and returned to the heart. If nothing happened, then our body was too boring, so that I was free all the time. Do this meaningless thing, is this possible?!” Daphus questioned and convinced everyone, and he replied categorically: “This is certainly impossible! The air and blood must have some wonderful things in the lungs. The reaction is just that our naked eyes can't see it, just as we can't see what is causing our wounds to infect. So what is this reaction? How important is our body?"

When the doctors heard this, they showed great interest. While thinking, they even erected their ears to listen to Daves' next speech.

Davers smiled: "I don't know what happens to blood and air, but we can find out the existence of this reaction through certain phenomena. Hulps, you can carefully observe the blood in the human body or animal body. Can you find out what is different in blood?"

"Blood?" Herpps fell into thought. To be honest, Daves’s speech today did not inform him in advance that he and other people are accustomed to the transparent air and have not considered this issue in depth. In addition, he has been the head of the Ministry of Health for the past two years, and he has served as the Dean of the Tuli Hospital and the Dean of the Diaonian School of Medicine. His administrative affairs have increased and he has lacked time to do medical research.

Stacy Codas next to it is also immersed in contemplation.

"Hey!" Someone suddenly remembered something and shouted: "It's color! The color of the blood!"

Daves fixed his eyes on it. The person who spoke was Kritos. He looked at the young doctor who was thinking and thinking. He quickly regained his gaze: "Yes, it is the color of blood! Medicine Doctors at the hospital~www.novelmtl.com~ As long as you have done the living anatomy of this animal, you will find that when the blood of the original color is in the lungs and is brought back to the heart by another blood vessel, the blood has become Bright and bright. Only the air and blood are flowing in the lungs, then there must be something in the air that has entered the blood, and the color of the blood has changed! And this kind of thing... this invisible thing has entered the bloodstream and started again. What is the role?"

Hulps, Stacy Codas, Kritos... All the doctors, including Lucassus, are now staring at Davers, all holding their breath, lest they miss a word.

Davers’s look is also serious: “We noticed that the blood that returned to the heart was pumped by the heart all over the body. The bright red blood is reflected in our body. Our lips are red, we The fingers are red, and our faces will turn red when they move. But when we see that a person has these characteristics, we can easily judge this person with years of experience in medical practice. Very healthy and very energetic. And we sometimes encounter such patients, their lips are purple, the ends of their hands and feet are black, their faces are blue, and the walk is trembling... We will also easily judge that this person is sick. And it is very ill. Isn't it because the two kinds of blood are mixed in and not mixed with this kind of thing from the air, and the changes in the body?! Can we think that this kind of thing is like food? The human body is indispensable, it makes us healthy and energetic?! Can we also make such inferences about patients with purple lips and black fingers, their trachea, or lungs, or Enter the lungs and blood vessels, or back to the heart blood vessels, which one way out of the problem, making this kind of thing in the air ultimately did not pass the blood out to the body?! ......
