On the dilapidated wall hung a strange shaped kerosene lamp, the lampshade was stained with some old blood, making the dim light seem to take on the blood color.
It was a small basement with a low ceiling and a lot of debris. Some of them bent down the old wooden floor, as if stepping on it would break the plank. There is a long wooden table in the middle of the basement. The light of the candle shakes, reflecting the extremely turbid color of the table top. Only when it has been stained with a lot of dirt, and has been penetrated into every wood grain, can it look like this
In the middle of the table, it seems that there is a corpse of an alien creature, which is filled with the stench of the sky, while there seems to be a figure standing by the table
Gu Jun wants to see clearly, but these illusions and shadows become vague and dim. What he sees in front of him is the anatomical table, and he is in the gymnasium.
"These tissues in this lung look like bird air sacs." Wang Ruoxiang tone is very surprised, her eyes open round, "just bigger."
"It's strange." Cai Zixuan wrinkled his slightly red and swollen eyes. What he said was the voice of all the teachers and students. The situation of the dissecting table was playing on the big screen.
There were six bronchioles on the outside of the bronchioles. They were all covered with capillaries.
Gu Jun looks at those airbags, and he has a feeling in his heart It's a wonderful structure.
Human beings always claim to be the essence of all things. The human body is really exquisite, but it is not perfect. On the contrary, it has many defects. Some organ structures are not better than those of other earth species.
The lung is one of them. The human lung is a two-way lung. The same path is used for air in and out, and the work of exchanging and storing gas is also needed. This makes the fresh air diluted by the residual hypoxia air in the lung, which is inefficient. And bubble wall is also very fragile, prone to emphysema.
But the lungs of birds are different. They have the front air bag, the lung and the rear air bag. The division of labor among these three parts is clear. The lung is only responsible for letting air pass through, and the air bag is only responsible for storing gas but not for gas exchange. In this way, fresh air can be constantly coming and going in and out of the lungs at a constant speed. Once inhaled and exhaled, there is oxygenated air passing through the lungs, which is very efficient. This is the "double breathing" of birds.
Therefore, birds can fly time and reach higher altitudes than humans.
Human beings may be able to say that "different species have different needs", but now, this humanoid creature on the dissecting table actually has a bird lung.
"Take it down and have a look." Gu Junning, with a pen gesture and a scalpel, bent over to cut off the pleura, nerves and blood vessels connected to the lung one by one, as well as the tube belts where the air bags attached to the surrounding parts, perhaps the lung roots and pulmonary ligaments, and a pile of tissues.
Because this is not drawn on the incomplete map, he must be careful in every operation, and can not cut any pipe. It's not just because Professor Qin is staring at them, it's also a requirement for the degree of task anatomy.
After Gu Jun took the lung out intact, he dissected it with Wang Ruoxiang and Cai Zixuan.
People can also observe more clearly. The more they look, the more surprised they are at this lung. It is almost that every artery and vein has exquisite and gorgeous planning.
"This creature should be able to climb higher and dive deeper." Cai Zixuan sighed, "this lung works too efficiently."
"I want this lung." Wang Ruoxiang said, "take it to participate. Good voice must be very suitable."
But soon she wanted the heart of this creature more.
After dissecting the lungs, the three men put their hands on the mediastinum, and then the pericardium. Gu Jun cut off the large blood vessels in the pericardium with the scalpel and took out the heart. This heart is one size larger than the human body. Although it is a dead mass now, it must beat with strength when it is alive.
They continued to observe and dissect the heart, and they were surprised.
The human heart is also imperfect, especially with a rather ridiculous defect - there is only one artery in each area of the heart, for example, the right atrium and right ventricle, and only the right coronary artery. If this artery is blocked, the right atrium and right ventricle will lack oxygen, then myocardial infarction, heart attack
Whether humans were created by the creator or evolved, this kind of humble design has to be criticized badly.
You should know that it does not need to be heterogeneous. Many mammals, such as dogs, are of the same species on earth. The dog's heart has multiple blood vessels in different paths. If one is jammed, the others can be topped. So dog lungs may not be good things, but dog hearts are.
"There are four coronary arteries in each of the four chambers." Wang Ruoxiang count way, light breath, "this will be very long life."
All the teachers and students were muttering and sighing.
But Professor Qin and their serious faces, these strange organs in their place, is nothing to praise.
"Professor Gu, is it possible that this is a human disease?" Xu Hai does not understand asked, Zhang Haoran and he Yuhan also do not understand, this is still a disease?
"Students, I don't know." Professor Gu sincerely sighed, his face was a little confused. What has he studied so many years?On the other side, Gu Jun continued to bury his head and dissect the coronary arteries on the heart one by one.
Every time he dissected one, his heart sank a little more, and he gradually felt the mood of those notes on the incomplete map. He was not only amazed at the structure of this creature, but also felt for its own structure Panic. There is no defect in the lung, no defect in the heart, is there no defect in other organs?
Subconscious complex emotions entangled, suddenly, Gu Jun's head a little painful, in front of his eyes there are illusions of light and shadow.
He felt that he was in the dark and narrow basement again, and a murmur came to his ears. It was that strange language
Although it was still a little vague, he saw it more clearly this time. On the long dirty wooden table was a humanoid corpse with dark skin and long limbs. The chest had been dissected, and the bone had been thrown aside. The light of kerosene lamp and candle illuminated the blood.
There is a rusty iron plate beside the table. A heart is placed in the plate. Its black and red blood flows out of the plate, falls on the table and drops on the floor.
Gu Jun vaguely saw that the figure standing at the table was holding something like a pen, leaning over a stack of yellowish parchment on the table with something written on it It's the old structural map! But in this vision, it's completely new.
While comparing the corpse on the table, the man drew a structural diagram on the paper, made notes and made notes.
As he wrote, he murmured something. He could not understand his face and his words, but could hear his surprise, panic, confusion and confusion
The more he wrote down the note, the more stiff the figure was and the more dead his voice was. He repeated his words slowly over and over again, as if he were about to die.
When he murmured for the fourth time, he also wrote down the fourth time on the map.
Gu Jun's heart aches. Suddenly, he seems to be able to understand this sentence and understand the meaning of the four lines of different texts repeated at the end of the note.
"Are they better than us?
Are they better than us?
Are they better than us?
They are better than us? "
