It was another morning, and Meng Lang came to the quarantine area as usual. It's been nearly three months since I first came here to cultivate.

Although he understands that everything has a gradual process, and he also knows the truth that if you want to hurry, you can't reach it, but he is inevitably still a little anxious in his heart!

When he woke up this morning, he found that his eyes had returned to their former black and white appearance, indicating that his cultivation was gradually on the right track, and it might not take long for the photoreceptor cells to successfully evolve the power of inner vision!

Thinking of this, he couldn't help but cheer for himself secretly! It was still the old place, and after sitting cross-legged for a while, there was a familiar burning sensation in his eyes.

At this time, he no longer needs to look at the photosensitive cell diagram to visualize, it is a very simple cell structure diagram, I believe that as long as he is not a fool, he can be familiar with it after reading it for nearly three months!

As usual, he slowly sketched the shape of the photoreceptor cells in his mind, and just as he was about to finish the final stroke, there was a sudden "buzz" in his head, and at that moment he seemed to see an organ shaped like a peach contracting and beating vigorously.

I was trying to take a closer look, but it was back to normal in an instant!

Meng Lang suddenly opened his eyes and opened his mouth slightly, revealing a look of disbelief.

He suppressed the ecstasy in his heart, then took a deep breath and sketched it in his mind again, and just as he finished the final stroke, he finally saw the scene in front of him, an organ the size of a fist and shaped like a peach beating vigorously and powerfully.

Yes, that's right, it's the heart!

I finally evolved the power of inner vision, and I succeeded! Meng Lang shouted frantically in his heart!

At this moment, a mysterious door of evolution finally opened slowly in front of him!

Suppress the ecstasy in your heart and wait for the excitement to calm down a little. Meng Lang once again set his eyes on his heart, which looked similar to what he saw on TV, an oval heart-shaped shape.

At this time, it is beating regularly, and every time it beats, it seems that you can hear a strong and powerful "dong" sound like beating a drum!

It's a wonderful feeling, as if a tiny high-definition camera suddenly appears in the body, transmitting everything in the body to your eyes.

And the lens of this camera can also zoom in and out with his thoughts, and can also rotate 360 degrees around his heart for observation.

This is a very busy organ in the human body, and in less than 20 seconds, the heart has to pump blood to every corner of the body.

In this cycle, the heart beats about 100,000 times throughout the day, and the average beats in a lifetime about 3 billion times!

With a daily pumping volume of 6-8 tons of blood, oxygen-rich blood travels a distance of about 96,000 kilometers through blood vessels, completing the arduous task of delivering blood to every cell in the body!

For a fist-sized muscle, this is obviously an unusually strenuous physical work.

With every beating and contraction of the heart, the bright red blood carries a large number of nutrients such as oxygen, glucose, and inorganic salts to be quickly transported to all parts of the body!

After looking at it with interest for a while, Meng Lang turned his gaze to the whirring lungs.

The lungs are not only the respiratory organs of the human body, but also one of the important hematopoietic organs of the human body!

Through the respiration of the lungs, oxygen is continuously inhaled, carbon dioxide is discharged, and the old is absorbed, so as to realize the gas exchange between the body and the external environment, so as to maintain the life activities of the human body.

There is probably no one in this world who forgets to breathe, which is actually controlled by the autonomic nervous system area in the brain.

When oxygen-rich air is inhaled, this area sends a signal to the muscles around the lungs, and the muscles that receive the signal begin to contract rapidly, creating more space for the lungs to expand to accommodate more air.

The air passes through the bronchi and then into the finer bronchiole ends, where there are a large number of capillaries.

According to statistics, all of them add up to 300 billion capillaries, and if you spread them all out, they are 2,400 kilometers long!

By this time, these capillaries are filled with carbon dioxide from all over the body. Follow the basic principle of diffusion from high concentration to low concentration.

Oxygen enters the blood vessels and is quickly captured by red blood cells, and at the same time, carbon dioxide also runs into the bronchial tubes and is exhaled out of the body to complete a breath!

Meng Lang continued to look down again, and came to the position of the spleen in the upper left side of the abdominal cavity. It is a dark red, oblate-oval organ and the largest lymphatic organ in the body.

It is not only the "blood bank" of the human body but also a "filter" of blood circulation, but its most important function is to produce various elite-level immune cells to help resist various bacteria and viruses that invade the human body from the outside world.

It stores blood when the body is resting, and when it is in the midst of intense exercise or sudden blood loss, it releases the stored blood to replenish the body's needs.

When germs, antigens, foreign bodies, protozoa, and senescent cells appear in the blood, macrophages and lymphocytes in the spleen will eat all these harmful things!

The liver is the largest organ in the human body, with an average adult liver weighing 1.5 kilograms and being made up of more than 3 billion liver cells.

In the state of inward vision, Meng Lang could see that these liver cells looked quite strange, not like the oval shape of most cells in the body, but polygonal with eight faces.

In addition to the peculiar appearance of the liver, the biggest difference between the liver and other organs in the body is that it has two thick arteries and blood vessels to provide it with dual blood supply, and its importance is self-evident!

The liver is like a large "chemical factory" in the human body, with hundreds of important functions!

In addition to synthesizing a variety of essential vitamins, balancing hormone levels in the body, and producing bile, it also breaks down toxic substances absorbed by people's gastrointestinal tract.

A series of complex detoxification processes break down some of the toxic substances into non-toxic substances, which are then excreted from the body through bile or urine.

But when detoxifying, due to the relationship between the blood flowing, it does not close the blood door to do this work, but detoxification while flowing, so it can never be detoxified, and there will always be some toxins in the blood.

Interestingly, even if the liver is cut in half, or if it is severely damaged, the remaining normal liver cells can still do various jobs as usual.

Meng Lang's gaze continued to fall, and then came to the position of the kidney. Needless to say, the importance of kidneys is well known to everyone on earth.

Traditional Chinese medicine believes that the kidney is the "innate root" and "the root of life", with one on the left and one on the left, similar to a broad bean.

It is like a "water purifier" in the human body, metabolizing waste 24 hours a day, and recovering various trace elements such as sodium, potassium, calcium, magnesium, etc.

Regulates body fluids and secretes endocrine hormones to maintain the stability of the human internal environment and enable the metabolism of various cells to function normally.

Meng Lang was like a bun entering the city at this time, and he was full of interest to visit all the hearts, livers, spleens, lungs and kidneys one by one!
