There is such a land, a country, it straddles Europe and Asia, half in Asia, half in Europe, it is surrounded by the sea on three sides, the Mediterranean Sea in the south, the Black Sea in the north, and the southern Aegean coastline in the west, about 1,600 meters long, the blue sea water adds a blue color to it, the unique natural resources have created its unique natural beauty, it was the center of the Byzantine Empire, and then became the center of the Ottoman Empire, inheriting the culture of the Eastern Roman Empire and Islamic culture, and there is a pious faith in the mosque.

I don't think all of these cells will die immediately after the death of the human body, but after that, these cells will all die slowly.

70 billion human cells die every day, and all of these cells are removed by phagocytes. In fact, phosphatidylserine exists in the cells of the human body, and when the cell is still alive, it exists in the cytoplasmic membrane, but when the cell dies, it will run out of the cell, and send a signal to other cells in the human body, "The cell here is dead", and when the phagocytic cell receives the signal, it will come to deal with it.
Phagocytes are actually a very large family, and the familiar white blood cells actually belong to phagocytes. There are a lot of phagocytes in the blood of the human body, about 1000ml of blood, there are 6 billion phagocytic cells, which means that the 70 billion cells that the human body dies every day may not be enough for them to stuff their teeth.
When phagocytes receive the signal, they move away from the vicinity of these dead cells. Phagocytic cells are actually a very important part of the body's immune system, as long as they sense that there are substances that will cause harm to the body, they will carry out phagocytic behavior, mainly phagocytosis of some bacteria and viruses, but when the body has no problems, they will also take on the responsibility of dealing with dead cells.
Phagocytes may be able to be cleaned in a few minutes near these desired cells. Phagocytic cells have digestive enzymes that can break down all the dead cells and then excrete the remaining waste products from the body. The products of its decomposition can also provide certain nutrients to the surrounding cells, and the normal metabolism of the human body will also excrete a part of the waste products.
Although 70 billion cells die every day, 70 billion new cells are produced in order to maintain the balance of cells in the body. However, not all cells in the human body are normal apoptosis, and some of them are necrotic due to the influence of diseases, which will affect the health of the human body. In the process of cell turnover, phagocytes play a vital role.
-
In fact, these cells die naturally, new cells are produced in our body every day, and some cells die of natural aging. There are about 13 trillion cells in the body of an average adult, and even if 70 billion die every day, it only accounts for the total number of cells, which does not seem to be too much.
-
The human body goes through metabolism many times a day, and these dead cells are metabolized cells, which are generally absorbed by the body or secreted from sebum.
-
These dead cells are excreted with the body's metabolism, but the body's cells have their own functions, constantly producing new fines, and have replaced these old cells.
-
Cells are still not good with the naked eye, but some of them are piled up, just like our longer and longer nails, which are actually made up of consumed cells.
-
If it is dead, it is invisible to the naked eye, and it may only be discovered with a microscope.
-
The key question is, how can the cells of the epidermis be exfoliated, but how can the cells of the internal organs be excreted from the body? It is impossible for these dead cells to pass through the cell membrane and enter the bloodstream for excretion.
-
It may be repurposed, and if it is not, it will be excreted directly from the body.
-
In the end, they are engulfed by phagocytes and become human excrement.
-
Re-enter the cells for use or be excreted from the body.
-
It is engulfed by phagocytes and excreted as metabolic waste.
-
In the end, they must all be excreted from the body, but the way of excretion is different.
-
It will be discharged into sewage and discharged into the human body.
-
There are so many human cells.
-
It is excreted from the body after various metabolisms.
-
When the cells are gone, they are gone.
-
Metabolic waste is excreted.
-
Not all cells die immediately, and the latest to die is xx cells.
The proportion of water in the human body is different at different times: in infancy, water accounts for 80%-90% of the human body; In adulthood, water makes up 75% of the human body; In old age, water makes up 65% of the human body.
Huh....I didn't see you showing your fart...I use it on my phone....Judging by what they give you, you should feel like you're still a good girl...There's nothing wrong with the D cup...Maybe you're developing early...Look at what you say, you should feel like you're in good shape....Why be fat? Maybe the most annoying thing for you is physical education class...No boy chasing me, it feels like you should be lying on your stomach in the seat every day....Even the boy who likes you won't confess to you...He may only like your appearance....I don't know what hobbies you have...Even if you talk to you, you may be afraid of embarrassment...So it's better for you to change your personality...Be cheerful....The girl learns to gossip about it....Take my word for it....You should have someone chasing you soon....Come on....If you're too fat, no one will chase you...Huh....
Global warming is a common topic for mankind, see Global Warming NorthThe polar snow melts, and polar bears are on the verge of itExtinction article. When I saw the fluffy and cute polar bear dying, I actually felt very sad in my heart. And that's not allDozens of cities around the world are sinking, and the polar bear's today may be humanity's tomorrow. >>>More
It is possible to move out, and the state should introduce corresponding policies to compensate the residents of these cities and maintain their livelihoods.
Whether it is an objective reason or a subjective reason, it is necessary to maintain a state of mind and a thought. People's path needs to be walked by themselves, and the direction of development of some things cannot be determined by themselves, but keep a good attitude and a healthy mind, whether you are rich or poor, famous or advantageous, you will have a dull life.
