There is no need to be too normal to be a doctor.

Chapter 28 Is it heartbeat?

"Why is Wu Tianjie gone?"

Chen Gong glanced at everyone curiously, and then added: "Why are you looking at me?"

"Pay attention to the dissection!"

As soon as these words came out, Tao Shengnan shuddered, always feeling that the anatomy room was a bit cold.

"Hurry up and do it."

Chen Gong urged.

Tao Shengnan was startled and nodded quickly: "Okay... okay!"

Originally, the most difficult thing about making a spinal animal, that is, a spinal frog, was the removal of brain tissue.

However, Chen Gong completed this set of actions in a few seconds, so that the subsequent process went very smoothly.

Tao Shengnan looked at the book and said: "The first is the scratching reflex."

At this time, Meng Ting quickly attached a small piece of filter paper soaked in 0.5% sulfuric acid to the skin of the lower abdomen of the frog.

Suddenly, the frog seemed to have reacted, and its limbs scratched here.

Several people watching this scene were pleasantly surprised!
"Oh my God, my head is gone...can I still react?"

"Sure enough, the brain is a lie!" Shou Weixiang looked at everyone with a mysterious face and asked in a low voice: "Do you know which organ is the smartest in the human body?"

Tao Shengnan blurted out: "Of course it's the head!"

Shou Weixiang smiled mysteriously as if he had discovered the truth: "This is the answer your brain tells you!"

"It's a hoax!"

Chen Gong rolled his eyes: "Who is the most handsome in our class?"

Shou Weixiang said with a dashing expression: "Of course it's me!"

Several people all gave their middle fingers: "Your brain is indeed a liar!"

……

Seeing how smooth the scratching reflex was, several people felt a sense of accomplishment.

And everyone around them was instantly attracted by the frogs scratching around.

"Monitor, why are you so fast?"

"Yes, how did you remove the frog's head?"

"Yeah, why can't I understand..."

"By the way, can we just cut off the frog's head?"

Before he finished speaking, a sudden burst of shouting filled the laboratory.

Looking around Xun Sheng, he saw only a girl covered in blood, with a lot of blood splattered even on her face.

It turned out that the boy who just said he was going to cut off the frog's head didn't know how to do it, and blood spattered out.

Seeing the chaos among others, Tao Shengnan and others were filled with a sense of superiority!

After all, they were almost done with the spine frog's reflexes.

At this time, the filter paper fell off and the headless frog calmed down. Meng Ting then rinsed her skin with clean water.

Shou Weixiang looked at Chen Gong seriously: "Chen Gong, can you teach me how to remove my head?"

Chen Gong immediately smiled and demonstrated the skills and techniques to Shou Weixiang.

Suddenly...

Shou Weixiang didn't want to do the experiment anymore.

After all, if you are young and promising and don’t show off, you might as well go back to the village and drive a tractor.

Now that I finally have a way to show off, how many tricks should I miss?
Here, Tao Shengnan and Meng Ting were conducting experiments seriously.

First, the skin of the frog was peeled off, and some sulfuric acid was dipped in filter paper to stimulate the toe tips, and the movement of the legs was observed.

The success of the first experiment made the two of them full of confidence and felt the joy of anatomy.

Before everyone around them officially started, a few people had basically completed the experiment.

Seeing Shou Weixiang acting cool everywhere, Tao Shengnan was also a little moved.

Leaving the frog behind for Chen Gong to take care of, he simply went to show off himself, euphemistically saying that he wanted to show off his demeanor as a squad leader.

Meng Ting was also called to help by a roommate.

Chen Gong and the headless spine frog were left to look at each other. The good frog could not be wasted.

This experiment seems to require observation of the frog's internal organs.

However, looking at the high-spirited Shou Weixiang, Tao Shengnan and others who were showing off everywhere.

Chen Gong had no intention of waiting for a few people.

He simply started taking action himself.

Observe the respiratory and circulatory mechanism of frogs from the nasal cavity, esophagus, lungs, skin, and heart blood vessels as a whole.

Well, then there's the digestive system.

Frogs have no teeth, but have tongues and abundant salivary glands to complete a preliminary swallowing digestive system.

Subsequently, the liver, pancreas, stomach, and intestines were separated to form the digestive system.

Then there are two kidneys connected to the veins.

Nervous system, muscular system...

At this time, Meng Ting came back. Seeing Chen Gong doing it alone, she couldn't help but ask:

"What are you doing?"

"babble?

Is this... frog's cow? "

Chen Gong nodded: "Do you know him?"

Meng Ting blushed: "Didn't you show it to everyone last time?"

"But what about his anus?"

Chen Gong smiled: "The frog's urethra, anus, and genitals are not differentiated, so they are located in the same mouth!"

When Meng Ting heard this, she suddenly trembled: "Eah? So disgusting?!"

"How dirty!"

"Can the female frog take it?"

Chen Gong smiled coquettishly: "We are all similar, no one dislikes anyone!"

Compared to Tao Shengnan, who is carefree, Meng Ting is a southern girl, quieter, tall and thin, with a soft facial features unique to the Jiangnan water town on her face, and a pair of big, round black-rimmed glasses on her nose. , a little more cute.

It's just... I didn't expect that the questions asked by the other party were so tough.

Shou Weixiang happened to be passing by and curled his lips: "The frog is so small!" Chen Gong glanced at the other party with disdain. We all took a bath together, so what are you pretending to be?

Even Meng Ting rolled her eyes and said, "You have to calculate it in proportion!"

Shou Weixiang felt bored and simply pretended to be cool.

With Chen Gong around, he couldn't find his presence.

Although Meng Ting is a pretty good girl, but...compared to my girlfriend, bah bah bah...

Shou Weixiang has not yet emerged from the shadow of muscle deficiency syndrome.

As a result, Meng Ting and Chen Gong were the only ones on the autopsy table.

"Wow!"

"Did you do all this?"

Meng Ting sighed in surprise as she looked at the complete systems on the side.

Chen Gong nodded and smiled: "Well, if I only do one experiment, I'm sorry for its physical body."

"If you want to save the soul of the dead, you need to fully tap its value and let him die a worthy death!"

Meng Ting covered her mouth and laughed: "Okay, Wu Tianjie was even scared away by you."

"But you are really awesome!"

Chen Gong smiled and said nothing.

Meng Ting just sat quietly watching Chen Gong's dissection.

Help hand over some items from time to time.

Chen Gong quickly completed the separation of all the frog's tissues, and even the frog's skeletal system was reassembled by Chen Gong.

"This is what anatomy is all about!"

Chen Gong sighed with emotion.

Meng Ting was stunned for a moment: "What do you mean?"

Chen Gong pointed to the frog's legs: "Look, the muscles of the frog's legs are much more developed than the forelimbs, and the most important thing is that there is a special connection between its joints and muscles that makes the frog's legs explosive. "

"Animals can often bring us some enlightenments, and they are also the ladder of human medical progress."

Meng Ting sat aside, holding her chin in one hand, tilting her little head, her big eyes through black-rimmed glasses, looking at Chen Gong's confident look, without hearing what he said, she smiled and praised:
"Well, you're right!"

"You know a lot..."

"Chen Gong, you are so amazing!"

Chen Gong also blushed a little after hearing these words.

"Yeah?!"

"The heart is still beating!"

Meng Ting couldn't help but say.

Chen Gong nodded and smiled, looked at the separated frog heart and said, "Do you want to see something exciting?"

There was a hint of smile in Meng Ting's big eyes, and she nodded happily: "I think so!"

Chen Gong smiled: "I will do an isolated frog heart perfusion experiment for you!"

"In fact, if the isolated frog heart that has lost its innervation is kept in a suitable environment, it can actually maintain a certain rhythm."

"The isolated heart is free from the direct influence of the body's innervation and body fluid factors. It can change certain components of the perfusate."

"I'll show you!"

While talking, Chen Gong placed the isolated circulatory system on the anatomy plate and watched the heart beating slowly.

Suddenly he took out a small container from his pocket.

"what is this?"

"Salt!"

"Why do you carry salt with you?"

"Isn't this an experiment? I want to try it...what, is it not normal?"

"Of course not. As a medical student, take it with yourself, there's nothing wrong with it!"

"Ha ha ha ha……"

Sure enough, the prerequisite for men and women to work together without getting tired is to have a sister who can praise her, like Meng Ting who is looking at Chen Gong with twinkling eyes.

This increased his self-confidence.

If there is a system prompt, you will definitely hear a sound [Ding!Confidence is greatly increased, and the experimental success rate is +30%. 】

The isolated frog heart perfusion experiment actually requires relatively complicated instruments, but... you can make do with it.

In this way, Chen Gong quickly completed the production.

He also brought some special salt and calcium and soaked them in water to form several reagents.

Not long after, as Chen Gong used different reagents to infuse into the heart...

Immediately!

The frog's heart instantly became excited.

With the addition of different reagents, the autonomy, conductivity, and contractility of the frog heart will change.

"Wow, how amazing!"

Meng Ting looked at Chen Gong and said excitedly.

He was obviously talking about the detached frog heart, but his eyes were staring straight at Chen Gong.

Chen Gong blushed a little, scratched his head and smiled: "It's okay!"

Meng Ting couldn't move her eyes away and continued: "Is this...the feeling of heartbeat?"

Chen Gong was so frightened that his hands trembled and he quickly stood up: "Well...I...I have to go to the toilet!"

After speaking, he ran away.

At this time, Qin Xuehai also noticed Chen Gong and stood beside him for a long time.

It also shocked me for a long time!
Chen Gong actually used the limited environment to isolate various systems of the frog, even retaining the integrity and functionality of the system, and even... conducted an "isolated frog heart perfusion experiment?!"

This... is simply unbelievable!
Not long after, Tao Shengnan came back happily. It felt so good to show off.

"Yeah?"

"What kind of experiment is this?"

"Why is your heart beating?"

Meng Ting smiled: "It's so exciting!"

Tao Shengnan was stunned for a moment and followed Meng Ting's eyes. Isn't it Chen Gong?
"Oops, can't you avoid your eyes?"
