"Why did Wu Tianjie leave?"

Chen Gong glanced at everyone with some curiosity, and added, "What are you looking at me for?" ”

"Dissection to focus!"

As soon as these words came out, Tao Shengnan shuddered, and always felt that this dissection room was a little cold.

"Let's do it."

Chen Gong urged.

Tao Shengnan was startled, and nodded hurriedly: "Okay...... Good! ”

Originally, the most difficult thing to make vertebral cord animals, that is, spinal frogs, was the removal of brain tissue.

But this set of actions was completed by Chen Gong in a few seconds, so that the next process was very smooth.

Tao Shengnan looked at the book and said: "First of all, it's the scratching reflex." ”

At this time, Meng Ting hurriedly pasted a small filter paper soaked in 0.5% sulfuric acid on the skin of the lower part of the frog's abdomen.

Suddenly, as if in response, the frog scratched its limbs at it.

This scene, a few people who watched it were pleasantly surprised!

"Oh my God, my head is gone...... Can this still be reactive? ”

"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!" ”

As if he had discovered the truth, Shou Weixiang smiled mysteriously: "This is the answer that the brain tells you!" ”

"It's a scam!"

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

Shou Weixiang looked dashing: "Of course it's me!" ”

Several people sent their middle fingers in unison: "Your brain is really a liar!" ”

……

Seeing that the scratching reflex was so smooth, several people were full of a sense of accomplishment.

And the surrounding people were instantly attracted by the frogs scratching around.

"Squad leader, why are you so fast?"

"yes, how did you get rid of the frog's head?"

"yes, why can't I read it......"

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

Before he could finish speaking, a sudden burst of screams filled the laboratory.

When I looked at the sound, I saw a girl covered in blood, and even her face was splashed a lot.

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

Seeing that other people were in a mess, Tao Shengnan and the others were full of superiority!

After all, they were almost done with the ridged frog reflex.

At this time, the filter paper fell, and the headless frog quieted down, and Meng Ting rinsed her skin with water afterwards.

And Shou Weixiang stared at Chen Gong and took a serious look: "Old Five, can you teach me how to get my head?" ”

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

Suddenly......

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

After all, if you are young and don't pretend to be forced, it is better to go back to the village and drive a tractor.

This finally has a way to pretend to be forced, and you can't miss a few hands?

And here, Tao Shengnan and Meng Ting are seriously experimenting.

First, the skin of the frog was peeled off, and the tips of the toes were stimulated by dipping some sulfuric acid in filter paper, and the movement of the legs was observed.

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

Before the crowd had officially started, several people had basically completed the experiment.

Seeing Shou Weixiang pretending to be forced everywhere, Tao Shengnan was also a little moved.

Leaving the frog for Chen Gong to take care of, he simply ran to pretend to be forced, and said in the name of showing the demeanor of the squad leader.

Meng Ting was also called by a roommate to help.

Leaving Chen Gong and the headless frog to look at each other, the good frog can't be wasted.

It seems that this experiment also requires the observation of the frog's visceral tissue.

However, looking at Shou Weixiang, Tao Shengnan and others who were pretending to be forced everywhere.

Chen Gong also didn't have the heart to wait for a few people.

I just started to do it myself.

The nasal cavity, esophagus, lungs, skin, and heart vessels were used as a whole to observe the respiratory and circulatory mechanisms of frogs.

Well, then there's the digestive system.

Frogs have no teeth, but have tongues and abundant salivary glands that complete the rudimentary swallowing digestive system.

Subsequently, the liver, pancreas, stomach, intestines are separated, and the digestive system is formed.

This is followed by two kidneys that are linked to the veins.

Nervous system, muscular system......

At this time, Meng Ting came back, saw Chen Gong doing it alone, and couldn't help asking:

"What are you doing?"

"Huh?

This is...... Frog's Cow Cow? ”

Chen Gong nodded: "Do you know?" ”

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

"What about his anus, though?"

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

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

"How dirty!"

"Can the female frog accept it?"

Chen Gong smiled: "Everyone is similar, no one dislikes anyone!" ”

Compared with Tao Shengnan's big grin, Meng Ting is a southern girl, more quiet, thin and tall, with a little soft facial features unique to Jiangnan Water Town, and a pair of big and round black-framed glasses on her nose, which is a little more cute.

It's just that...... I didn't expect the other party to ask such a strong question.

Shou Weixiang happened to pass by and pouted: "This frog thing is so small!" ”

Chen Gong glanced at the other party with disdain, everyone is a person who has taken a bath together, what are you pretending?

Even Meng Ting rolled her eyes and said, "You have to calculate according to the proportion!" ”

Shou Weixiang felt bored and simply pretended to be forced.

With Chen Gong here, he couldn't find a sense of existence.

Although Meng Ting's sister is also very good, but ...... Compared to his girlfriend, Bah Bah ......

At present, Shou Weixiang has not come out of the shadow of muscle deficiency syndrome.

As a result, there were only Meng Ting and Chen Gong on the dissection table.

"Wow!"

"Did you do this?"

Looking at the complete systems on the side, Meng Ting sighed with some surprise.

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

"If you want to surpass the revenant, you need to fully tap its value and let him die a well-deserved death!"

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

"But you're really good!"

Chen Gong smiled and did not speak.

Meng Ting just sat quietly and watched Chen Gong's dissection.

Help hand over some items from time to time.

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

"That's what anatomy is all about!"

Chen Gong sighed.

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

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

"Animals often give us some inspiration, and they are also the ladder of human medical progress."

Meng Ting sat on the side, holding her cheek with one hand, tilting her little head, her big eyes through black-framed glasses, looking at Chen Gong's confident appearance, she didn't hear what he said, so she praised with a smile:

"Well, you're right!"

"You know a lot......"

"Chen Gong, you are so amazing!"

Chen Gong also blushed a little when he said this.

"Babble?!"

"My heart is still beating!"

Meng Ting couldn't help but say.

Chen Gong nodded and smiled, looked at the detached frog heart and said, "Do you want to see a wonderful thing?" ”

Meng Ting had a little smile in her big eyes, and nodded happily: "Yes!" ”

Chen Gong smiled: "I'll give you an isolated frog heart perfusion experiment!" ”

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

"The isolated heart, on the other hand, is detached from the body's innervation and the direct influence of the whole body fluid factor, which can be done by altering some components of the perfusion fluid."

"I'll show you!"

As he spoke, Chen Gong put the separated circulatory system on the dissecting plate and watched his heart beat in a slow rhythm.

Suddenly, a small vessel was taken out of his pocket.

"What's this?"

"Salt!"

"What are you doing with salt?"

"Isn't there an experiment? I want to try...... Why, isn't it abnormal? ”

"Of course not, as a medical student, I brought salt to myself, and there was nothing wrong with it!"

"Hahahaha......"

Sure enough, the premise of working with men and women without getting tired is to have a younger sister who can be praised, such as Meng Ting looking at Chen Gong with little stars in her eyes on the side.

This gave him an increase in self-confidence.

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

In vitro frog heart perfusion experiments require relatively complex instruments, but ...... It will be okay to do it.

In this way, Chen Gong quickly completed the production.

He also brought some special salts and calcium, soaked in water to form several reagents.

Not long after, Chen Gong was perfused into the heart with different reagents......

Suddenly!

The frog's heart instantly became excited.

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

"Wow, that's amazing!"

Meng Ting on the side looked at Chen Gong and said excitedly.

Obviously, he was talking about the heart of the frog out of the body, but his eyes were staring directly at Chen Gong.

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

Meng Ting couldn't take her eyes off, and continued to say: "This is ...... Heartbeat? ”

Chen Gong's hands trembled with fright, and he quickly stood up: "This...... I...... I need to go to the toilet! ”

After saying that, he fled in the wilderness.

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

It's been a long time coming!

Chen Gong actually took advantage of the limited environment to isolate the various systems of the frog, and even retained the integrity and functionality of the system, and even ...... It was made into an "ex vivo frog heart perfusion experiment?!" ”

This...... It's incredible!

It didn't take long for Tao Shengnan to come back happily, and it felt so good to pretend to be forced.

"Hubble?"

"What kind of experiment is this?"

"Why is my heart beating?"

Meng Ting smiled: "It's exciting!" ”

Tao Shengnan was stunned for a moment, and looked at Meng Ting's eyes, wasn't it Chen Gong?

"Oops, can't hide your eyes?"
