A strange-looking kerosene lamp hung on the dilapidated wall. The lampshade was stained with old blood stains, making the dim light seem to be tinged with blood.
This is a small basement. The ceiling is very low, and there are piles of debris everywhere. Some of them are bending the old wooden floor, as if the board will be broken if you step on it. There is a long wooden table in the middle of the basement.
, the light of the candle swayed, reflecting the extremely turbid color of the tabletop. Only if it has been stained with a lot of dirt, and the dirt has penetrated every wood grain, can it look like this...
There seemed to be a corpse of a strange creature placed in the center of the table. The stench filled the sky, and there seemed to be a figure standing beside the table...
Gu Jun wanted to see clearly, but these phantom lights and shadows became erratic and faint. What he saw in front of him was still the dissecting table, and he was in the gymnasium.
"These tissues in the lungs seem to be bird air sacs." Wang Ruoxiang sounded surprised, her eyes widened, "It's just bigger."
"That's really weird." Cai Zixuan wrinkled his slightly red and swollen eyes. What he said was really the voice of all the teachers and students present. The situation on the dissection table was played on the big screen.
There are six enlarged membranous sacs growing on the outside of this lung, all connected to the bronchi. The walls of the sacs are covered with capillaries, showing that they were once full of vitality.
Gu Jun looked at those air bags, and a feeling surged in his heart... Such a structure is really wonderful.
Human beings always pride themselves on being the spirit of all things. The human body is indeed very delicate, but it is not perfect. Instead, it has many flaws. Some organ structures are not better than those of other earth species.
The lungs are one of them. Human lungs are bidirectional lungs. Air enters and exits through the same path, and it also needs to exchange and store gases. This causes the newly incoming air to be diluted by the remaining hypoxic air in the lungs.
The efficiency is low. Moreover, the bubble walls are very fragile and emphysema is prone to occur.
But the lungs of birds are different. They have front air sacs, lungs and rear air sacs. These three parts have a clear division of labor. The lungs are only responsible for letting air pass through, and the air sacs are only responsible for storing gas but not performing gas exchange. In this way, fresh air can be
The lungs constantly come and go at a constant speed, and every time they inhale and exhale, oxygen-containing air passes through the lungs, which is very efficient. This is the "double breathing" of birds.
Because of this, birds can fly for long periods of time and reach higher altitudes than humans.
Humans may be able to argue that "different species have different needs." However, now, this humanoid creature on the autopsy table actually has a bird's lungs.
"Take it off and have a look." Gu Jun concentrated his mind, held the scalpel with a pen-holding gesture, and leaned over to cut off the pleura, nerves and blood vessels connected to the lungs, as well as the tubes around the air sacs attached to them.
Maybe there are also lung roots and pulmonary ligaments, a bunch of tissue.
Because this was not shown on the incomplete map, he had to be careful in every operation and not cut any tube. Not only because Professor Qin and the others were watching, this was also a requirement for the completion of the anatomy task.
After Gu Jun removed the lung intact, he would dissect it with Wang Ruoxiang and Cai Zixuan.
Everyone was able to observe it more clearly, and the more they looked at it, the more surprised they were by this lung. Almost every artery and vein had a delicate and gorgeous plan.
"This kind of creature should be able to climb higher and dive deeper." Cai Zixuan said with emotion, "This lung works so efficiently."
"I want this lung." Wang Ruoxiang said, "It will definitely be suitable for participating in The Voice."
But she soon wanted the heart of this creature even more.
After the three people dissected the lungs, they moved to the mediastinum, then the pericardium. Gu Jun used a scalpel to cut off the large blood vessels in the pericardium and took out the heart. This heart was one size larger than the human body, even though it was now a lifeless mass.
, but it definitely beats with power when it’s alive.
They continued to observe and dissect the heart, and they got another surprise.
The human heart is also imperfect, especially with a rather ridiculous defect. Each area of the heart only has one artery supplying blood. Take the right atrium and right ventricle, for example, they are only supplied by the right coronary artery. If this artery is blocked, the right coronary artery will
The atrium and right ventricle will be deprived of oxygen, and then myocardial infarction, heart attack...
Regardless of whether humans were created by the Creator or evolved, this shabby design deserves a bad rap.
You need to know that they don’t need to be aliens. Many mammals that are the same species on earth, such as dogs, have multiple blood vessels supplying blood through different paths in the dog’s heart. If one is blocked, the others can still push on. So dog lungs may
It's not a good thing, but a dog's heart is.
"Each of the four heart chambers has four coronary arteries supplying blood." Wang Ruoxiang counted and took a breath, "This will help you live a long life."
All the teachers and students in the audience were muttering and sighing.
But Professor Qin and the others looked serious. These strange organs were not something worthy of praise for them.
"Professor Gu, is it possible that this is caused by a human disease?" Xu Hai asked in confusion. Zhang Haoran and He Yuhan also couldn't figure it out. Is this still a disease?
"Students, I don't know." Professor Gu sighed sincerely, with a bit of confusion on his face. What have he been studying for so many years?
On the other side, Gu Jun continued to immerse himself in the operation, dissecting the coronary arteries on the heart one by one.
With each section, his heart sank a little heavier, and he gradually felt the emotions of the notes on the incomplete atlas. He was amazed by the structure of this creature, and felt... panicked by his own structure. There were no defects in the lungs.
, the heart is not defective, does it mean that there are no defects in other organs?
In particular, what about its brain?
The reason why humans can dominate other species and suppress tigers and lions depends on intelligence.
What is the level of intelligence of this creature?
If the human body has no advantages and the brain has no advantages, then...
The complex emotions in his subconscious were entangled. Suddenly, Gu Jun's head felt a little heavy, and phantom lights and shadows flashed in front of his eyes.
He felt that he was in the dark and cramped basement again, and a murmur reached his ears, which was that weird foreign language...
Although it was still a little blurry, he could see it more clearly this time. There was a humanoid corpse placed on the dirty long wooden table. The skin was dark, the limbs were very long, and the chest had been dissected.
A piece of bone was thrown aside, and the light of kerosene lamps and candles illuminated the bloody scene.
There was a rusty iron plate beside the table, and a heart was placed on the plate. Its black and red blood flowed out of the plate, fell to the table, and dripped on the floor.
Gu Jun vaguely saw that the figure standing by the table was holding something that looked like a pen, leaning over and writing something on a stack of yellow parchment on the table... It was the old piece of paper. Structural diagram! But in this illusion, it is still complete and new.
While comparing the corpse on the table, the man drew a structural diagram on the paper, marked it, and wrote down notes.
He was mumbling something while writing. I couldn't see his face or understand his words, but I could hear his surprise, panic, confusion, and confusion...
The further the note goes, the stiffer the man's posture becomes and the deadlier his tone becomes. He slowly repeats his words over and over again, as if he is about to die.
When he muttered it for the fourth time, it was also the time to write it down on the map for the fourth time.
Gu Jun's heart ached, and he suddenly seemed to be able to understand this sentence, and knew the meaning of the four repeated lines at the end of the note.
