Chapter 522

After the earthworm is cut in two, it can become two earthworms.

First of all, the muscle tissue on the cross-section will contract immediately, part of the muscle will quickly dissolve by itself, thus forming a new cell mass. The white blood cells will also coagulate to the section at the same time to form embolism, so as to make the wound close quickly, prevent blood loss, tissue fluid loss, and resist the invasion of micro organisms.

In this way, the earthworm can survive after forming a closed body cavity, which is the stage of regeneration.

At present, there are two hypotheses about the mechanism of earthworm regeneration.

One is that after the body cavity is closed, the primary cells in the septum of the body cavity will quickly move to the cross-section and form nodular regenerative buds together with the muscle cells dissolved by themselves. At the same time, a large number of mitosis is carried out in vivo, and the cells of digestive tract, nervous system, blood vessels and other tissues grow rapidly to the regeneration bud site.

The second is that the cells on the cross section will be dedifferentiated and return to the original undifferentiated state, and then these cells will divide, differentiate, grow and regenerate.

Both hypotheses lead to the same result.

In this way, a new head will grow on the section without head, and a new tail will grow on the section without tail.

One earthworm becomes two complete earthworms.

Earthworm is also a kind of life.

Is this leg of sheep still alive?

When Gu Jun heard Wu Shiyu's words, his first reaction in his mind was to think of earthworms. Then he looked at the broken giant leg of sheep, as if he could clearly see that the subcutaneous tissue of its thigh was dissolving itself.

Different from earthworm, its biological mechanism is more complex than earthworm,

when the liquid escaped, re condensed, and then through a regeneration process, it became another black goat cub.

Almost instantaneously flashed these thoughts, Gu Jun's head more intense pain for a while, illusion feeling in aggravation.

But at the same time, the new system panel's ability to investigate the column, the experience of anatomy has also increased.

Gu Jun was a little surprised, but the introduction of anatomy has already said that the purpose of anatomy is to understand the profound meaning of life through anatomy, which is not only the use of knives and scissors, but also the measurement, observation and summary are effective method.

"I feel the stick insect." Wu Shiyu quickly walked to the side, "it is playing dead."

The insect has the ability to regenerate severed limbs.

"Earthworms." Gu Jun also said the idea, "I suspect it is dissolving itself, preparing for regeneration."

Listen to two people say so, Wang Ruoxiang, egg uncle, Xiao Huiwen and other people suddenly realize some, self dissolution? Regeneration? Wang Ruoxiang asked in a hurry: "Gu Jun, do you want us to get off the car immediately, open the freezer, and freeze it all first."

Now there are two crises. One is to get away from the liquid, but this is not urgent because the carriage is sealed and every drop of liquid from the leg is put into the isolation barrel. What is urgent is another crisis. If it goes on like this, the leg of sheep will completely dissolve.

What Wang Ruoxiang said is a way, but can freezing really stop it?

Water begins to freeze at zero centigrade, but the tissue fluid of insects can withstand the low temperature below zero without freezing, which is called "supercooling phenomenon".

There are also cell activities. Freezing can not completely stop the cell activities of some ordinary life, and this is abnormal life

"Try freezing some liquid first! See if there is supercooling. " Gu Jun said as he turned his mind to "46505000 (Level 1 and level 9)" column in his mind. He was almost able to upgrade. After upgrading, he might get a reward

There is still 300 experience to go. In the face of a new type of contact, there is still a chance to improve before the deep understanding.

While Wang Ruoxiang and uncle egg were in action, he looked thoughtfully at the liquid that dyed the drainage tube dark green.

The human body naturally has a lot of fluid. In fact, about 60% of the body weight of each person is body fluid, which is divided into two parts, about two thirds of the intracellular fluid and about one third of the extracellular fluid. Tissue fluid, which belongs to extracellular fluid, can account for about 16% of body weight.

This concept belongs to the category of physiology.

Because anatomy is primarily about figuring out the hierarchical structure of the biological body.

But what about anatomy in a broad sense? What if black goat cubs have different body shapes?

"This is not a dirty liquid..." Gu Jun thought of murmuring, reaching out to the leg of the sheep, stained with a little dark green liquid. Even though he was separated from the protective clothing, he seemed to feel its viscosity and heat. "This is the tissue fluid of black goat cubs, which may be all over its body..."

"Do you mean that it can be regenerated by dissolving itself into a liquid?" asked Xiao Huiwen, who was on the communication screen

"Hypothetical, a hypothetical." Gu Jun picked up the kalop scalpel in his hand and thrust it into the shriveled epidermis of the leg's thigh and cut it with clenching teeth. "This liquid can not only make it grow, but also repair its damage, as well as metamorphosis and regeneration..."Only the species with such ability can be called as having strong fecundity, insect like ability and insect like fecundity.

It won't be killed easily. Death is just the beginning of regeneration.

One offspring is thousands of children.

Whew! Gu Jun cut a small piece of the skin of the leg of mutton. When he lifted it up, he saw that the inside of the leg was broken and fuzzy. Some of it was dark green liquid, and some was dark red liquid that was dissolving from flesh and blood, and then it turned to dark green

"It can be perverted." He murmured, "its structure can change."

On the other side, Wang Ruoxiang collected a small cup of liquid, and then put it into a - 20 ℃ refrigerator.

However, after a while, the foreign liquid in the box was guessed by Gu Jun, and there was no sign of freezing in the measuring cup!

And the dark green liquid seems to be stirring slowly, as if there is life.

The anatomy experts were stunned. Xiao Huiwen asked anxiously, "how should we stop it? We still have to study this form... "

"Yes, yes!" Geely clapped her thighs and made a gesture, "stop now!"

Gu Jun looked at the glass of ice free liquid, thinking that there was really a cooling phenomenon

All of a sudden, he just felt his spirit in his mind, and the degree of completion of the task's anatomy had increased to 0.51%. There were several messages popping up in succession:

[you have improved your understanding of life by observing black goat cubs, + 300 experience value, 50005000 (level I, level 9)]

[your investigation ability "Anatomy" level has been improved! It is currently 015000 (Level 2 and level 9)]

[you have new skills available in anatomy! 】
