Mediterranean Hegemon of Ancient Greece

Based on this, Dionia is the place where Greek doctors aspire.

Daphes broke apart the outer skin of the model's mandible and neck, exposing the inner channel: "Look, the mouth and nose channels are merged here, and then divided into two channels -"

He pointed to a hose made of nitro leather: "We all know that the nose is used to breathe air, but the mouth not only breathes air, but also eats and drinks water. Air and food go through different channels, and After long-term observation by medical school doctors, they think that this tube is taking air, and it is called the trachea. And the other channel behind him, through food and water, we call it the esophagus. Everyone touches themselves. Below the neck, the hard bumps under the skin are not smooth and are the trachea.

The Gentile doctors under the pulpit really touched their necks with their hands and realized what Daphs said about the trachea.

"Someone may ask if the openings of the esophagus and trachea are connected together, wouldn't it be easy for food and water to enter the trachea?" Daveus said, and many people nodded, so he laughed: "Fact It’s almost impossible. There is a very soft bone at the opening of the trachea. When we swallow, it will automatically cover the opening of the trachea, and will not let food and water enter the trachea. If everyone has Interested, when the meeting is over, you can come and take a look. This mannequin made by our Dionysian craftsmen with superb skills under the guidance of a doctor is quite accurate. However, don’t break it, this model is The treasure of the township hospital of the medical school can’t be bought for any amount of money! I’m right, Helps."

"Yes, Mr. Davers. We usually use it only when we are teaching, and it is generally not touched." Helps smiled.

According to Daphes and Helps, the Gentile doctors were very irritated and stood up one after another, looking at the mannequin beside Daphes, the scene was a little messy.

Daveus continued to ask: "I heard that the young medical doctor Dr. Critos who discovered this cartilage. For this reason, he also specially dissected live pigs and sheep, and carefully observed the movement of this cartilage. And mechanism, right?"

"Yes." Helps nodded.

"Is he here today?" Daveus asked with a smile.

"coming."

"Then, please ask Dr. Critos to stand up and let everyone know." Daveus said with a smile.

Critos stood shyly under the push of his colleagues.

"Let us thank Critos for this important discovery with warm applause!" Daveus took the lead in applause, and then there was a warm applause, and his classmates even whistled in excitement.

Critos was nervous and excited.

Lucasus looked enviously at Critos, who was standing in front of him: This doctor, who seemed to be about the same age as him, was shyly accepting the applause of the audience. When could he become famous in Greece like him, and Isn’t Tiantian always an apprentice like a slave?

"Critos, I look forward to you discovering more in medicine and making greater achievements!" Daveus encouraged him enthusiastically.

It seems ridiculous for a young man to encourage another young man with the tone of an elder, but most of the doctors present do not think so.And Critos was so excited that his chest fluctuated sharply: "Okay...Okay, Mr. Daphes!"

After Critos sat down, Daphes continued: "If you don't take food seriously sometimes, there will be a sudden choking, which is actually the cartilage covering the trachea in time, causing food to enter the trachea; if when a mother holds When the baby is looking for you to see a doctor, telling you,'The child coughs more than once while drinking milk', in fact, it may be because of this reason...

What Daphs said made the Gentile doctors remember it and confirmed the similar cases he had seen before.

"The air went down the trachea to an organ. The Dionysian School of Medicine, after many anatomies, called this trachea the lung." said Daveus, breaking open the chest of the mannequin and dismantling the left lung carved in wood. And show it to everyone.

"As a result, the medical school found that there are two lungs on the left and right sides of our body, which are like pig urine bubbles played by children. When inhaled, the air enters and the lungs expand; when exhaled, the air is expelled The lungs will shrink. Everyone may be surprised that the air enters the lungs from the mouth and nose, and then exhales from the lungs, so it turns around and returns to the original point. It seems meaningless. But I tell you, we The body is the most precious treasure that the gods have given to the world. It is so wonderful that it never does meaningless things!"

The doctors under Davies looked around and saw that they were all listening attentively, and said seriously: "After many dissections of the corpse, the medical school found that the trachea entered the lungs and continued to divide down the thinner tubes. Like the branches of the big tree, how big is the trachea that we can finally see?"

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

At this time, a young Dionysian doctor stood up: "It is a blood vessel! We found that there were many same small blood vessels intertwined with these trachea during the dissection. These small blood vessels are two large blood vessels from the heart. Continue to differentiate..."

"So, what's the use of these two large blood vessels from the heart?" Daveus continued to ask.

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

"What other obvious difference?"

"Well... it's a blood vessel that pumps blood, and two blood vessels that come back..." the young doctor replied hesitantly.

"This is different, is there any?"

"Uh..." The young doctor blushed and couldn't answer.

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

"Strobes of Dionysian Medical School."

"Thank you for your wonderful answer, you said very well!"

Strobus, who was slightly frustrated, smiled again when he heard Davers' praise.

"Everyone, the air circulates in the lungs and goes out again, the blood circulates in the lungs and goes back to the heart. If nothing happens, then our body is too boring, so that we are always idle. Is it possible to do such a meaningless thing?" Daveus questioned, and at the same time pondered everyone, he replied categorically: "Of course impossible! Air and blood must have some kind of wonder in the lungs. The response is just invisible to our naked eyes, just like we can’t see what infects our wounds. So what is this response? How important is it to our body?"

When the doctors heard this, they all showed great interest. While thinking, they even raised their ears and listened to Davis's next speech.

Davies smiled: "Although I don't know what happens to the blood and the air, we can discover the existence of this reaction through certain phenomena. Helps, you have carefully observed the blood in the human or animal body ?Do you find any difference in blood?"

"Blood?" Helps fell into thought.To be honest, Davers did not inform him of the topic of his speech today. He is as accustomed to transparent air as everyone else, and has not considered this issue in depth.Coupled with the fact that he has been the director of the Ministry of Health for the past two years, as well as the dean of Turriy Hospital and the dean of Dionys Medical College, administrative matters have increased, and he has lacked time to do medical research.

The Stacey Kodas beside him was also in deep contemplation.

"Oh!" Someone suddenly remembered something and yelled, "It's color! The color of blood!"

Daveus looked closely, and it was Critos who spoke. He glanced at the thoughtful and creative young doctor, and then quickly looked back: "Yes, it is the color of blood! Medicine Doctors in the hospital, as long as you have done an animal biopsy in this area, you will find that the blood of the original dim color enters the lungs, and when it is brought back to the heart by another blood vessel, the blood has become bright. Only in the lungs Air and blood are flowing, then something must have entered the blood in the air, and then the color of the blood has changed! And this kind of thing... what role does this invisible thing enter the blood?"

Helps, Stacy Codas, Critos... All the doctors, including Lucasus, were staring at Daphes at the moment, holding their breaths, lest any word be missed.

Dave's expression also became serious: "We noticed that the blood back to the heart was pumped all over the body by the heart again, and the bright red blood was reflected in our bodies. Our lips are red and red, we Fingers are red and red, and our face will become red after exercise... But when we see a person with these characteristics, we can easily judge this person with many years of medical experience Very healthy and energetic. We sometimes encounter patients with dark purple lips, black hands and feet, blue face, trembling walking... We will also easily judge that this person is sick , And the disease is very serious. Isn't this the change in the body that these two kinds of blood are mixed in and not mixed in from the air?! 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 an inference for this kind of patients with purple lips and black fingers, their trachea, or lungs, or into the lungs Blood vessels, or blood vessels back to the heart, one of these pathways has a problem, so that this kind of thing in the air eventually failed to reach the whole body through the blood?!......"
