Is death a characteristic of living things?

Maybe it doesn't be, maybe it's just metabolism.

Many scientists are looking for ways to save people from dying.

That is, death is not a characteristic of living beings.

If you were a scientist, you wouldn't work so hard.

Because death is a biological feature, it is inevitable (if we speak of the breakthrough creatures themselves).

It can be explained in this way.

Recent studies have shown that life dies in order to better adapt to the environment (perhaps a little absurd).

But this is the case, if a living organism does not change, and the most direct change in nature is death and rebirth.

Because genes are not changed casually, even if you modify the life genes on the body, it is difficult to reflect them on the surface, because the old genes have already created him and cannot be changed. Unless it is allowed to reproduce – to be reborn, so that the modified genes will manifest themselves in the offspring of the ontology. So the need - death.

It can be said that "death" is like a rhinoceros with horns, in order to live better - it is a survival mechanism, not a life characteristic.

If you think "grow and reproduce" can also be explained in this way.

Then you think like this - except for the factors of being forced by society or being empty and boring to a certain extent, no one will want to die, but they will want to grow up and think about that.

This can be said to be an ideological distinction between "death" and "growth and reproduction".

Death is metabolic! I have consulted my teacher.

Be. Creatures reproduce, grow, and die. It can be summed up.

From a cellular point of view, there is aging and death, and the renewal of biological structure is completed.

The death of an individual biological is not a characteristic.

The characteristics of death are:

1. The edema gradually subsides: many elderly people will have more or less edema, and many people will gradually subside in a period of time before their deaths, and then their hands and feet will also be emaciated.

2. Begin to talk nonsense: Before they die, many old people will confess some things that are rarely mentioned or secrets that have been hidden in their hearts for many years. Others have strange dreams. Most of the old people seemed unusually silent and calm after saying something.

3. Emptying stool: A large proportion of the elderly will empty their stomachs and intestines, that is, defecate, before they die. There are also a small number of people who have a bowel movement within an hour of breath.

Types of Death:

Death is divided into two categories: physiological death and declared death. Physiological death is defined as death when a citizen's heartbeat, breathing, and brain have stopped. Declaring death refers to the act of declaring the death of a citizen whose whereabouts have been unknown for a certain period of time, upon the application of an interested party.

Death refers to the loss of life, the termination of life, the cessation of life, which is the opposite of survival. Philosophically speaking, death is the loss and irreversible permanent termination of all the attributes of a living (or thing) system that originally sustained its existence (survival).

A shocking study in the United States has shown that when a human heart stops beating, the brain continues to function. In other words, the human brain becomes aware of the fact that it is dead.

Brief introduction. Death is the irreversible and permanent termination of all the attributes of a living (or thing) system that originally sustained its existence (survival). While death has a systemic legacy, it does not restore it to the pre-termination living system.

In general, the death of an organism refers to the loss and permanent termination of all its vital features, and its eventual transformation into an inanimate object.

Death is a link in the natural circulation chain, an inevitability in the changing world. The legacy of the post-death system is a necessary material for other existing or new things.

The three main characteristics of death are cessation of breathing, cessation of the heart, and emanation of pupils. Later, with the gradual development of medicine, the exception of the stop of the heart beating. So, the three characteristics of death become two major characteristics, not including the cessation of the heart.

Death refers to the loss of life, the termination of life, and is the opposite of survival. Philosophically speaking, death is the end of life, and the loss of all the attributes that originally sustained its existence (survival), irreversibly and permanently. And a shocking study in the United States shows that when the human heart stops beating, the brain continues to function.

In other words, the human brain becomes aware of the fact that it is dead.

The characteristics of the three stages of medical death are as follows:

1. Near-death period (dying period).

It is the loss or deep inhibition of the nerve function above the brainstem, while the nerve function below the brainstem is still alive but is in a state of infiltration disorder due to the loss of control of the upper central nervous system. The patient presents with confusion, circulatory failure, respiratory failure, metabolic disorders, obtundation of various reflexes, loss of muscle tone.

2. Clinical death.

It is a state of deep inhibition and loss of function outside the brain, so various reflexes are lost, and breathing and heartbeat are stopped.

3. Biological death period.

It is the final stage in the process of dying. At this time, the metabolism of the entire nervous system and other organ systems has stopped since the cerebral cortex, and the whole body has irreversible changes and can no longer be resurrected, but individual tissues can still have very small metabolic activities in a certain period of time.

As for the criteria for death, the medical profession has always regarded respiratory and cardiac arrest as the only criteria for death, and regarded cardiopulmonary function as the most essential feature of life. Modern medical research has shown that death is a continuous progression. Since the forties of this century, due to the wide application of medical engineering technology, resuscitation has been continuously improved, and people who have stopped their heartbeat and breathing can still be resuscitated.

Patients with extensive necrosis of brain cells can still maintain their heartbeat and breathing for a long time due to the application of artificial ventilators. But once the ventilator is removed, breathing and heartbeat stop immediately. The above shows that the cessation of cardiopulmonary function does not necessarily mean death, and the dependence on artificial maintenance of cardiopulmonary function does not mean that the survival of the heart and lung function will continue to exist, which makes the traditional standard of death face new challenges.

Since brain death is irreversible, some scholars have proposed loss of brain function as the criterion for death. At the 22nd World Medical Congress held in 1968, "irreversible loss of brain function" was proposed as the diagnostic criterion for death. Since then, the United States has also formulated four criteria for Harvard brain death and a definition of death.

The biological death period is the final stage of the death process.

During this period, the metabolism of the entire central nervous system and various organs of the body is terminated one after another, and irreversible changes occur.

At this stage, it is impossible for the entire organism to be resurrected.

Moreover, with the progress of this period, some corpse phenomena will appear one after another, such as corpse coldness, corpse spots, corpse stiffness, corpse decay, etc.

The main characteristics of death are ().

a.Non-fungibility.

b.Irreversibility.

c.Inevitability.

d.Sociality.

e.Mystery.

Summary. It is speculated that human activities are driven by human bioelectricity, similar to the role of electrons, and the electron carrier is the body, when the body mass declines and cannot carry electronic activities, the electrons will migrate outward, which is brain death, and the decline in body mass includes trauma, aging, etc.

What is biological death.

Biological death, also known as "brain death". A process in which the vital physiological functions of the whole body stop and fall into an irreversible state. First of all, the cerebral cortex, and then the entire central nervous system undergoes irreversible changes, and then the functions of various organs and tissues disintegrate one after another, and the brain function is permanently lost.

Can you tell us more about that?
