Ensayo, ¿Qué es la Vida?

 La vida, impredecible e indefendible

"El ser vivo se mueve, cambia, y sus movimientos y modificaciones tienen su origen en él mismo: son espontáneos"                                                                                                                          – Aristóteles

La comunidad social se a preguntado el porque de la vida y cual fue su origen, gracias a nuestros ancestros que aportaron teorías a base de experimentos, hasta el momento han sobresalido y nos han podido dar respuesta a nuestras preguntas. Pues los seres vivos son organismos que nacen, se nutren, respiran, se desarrollan, crecen, reproducen y mueren, y así es nuestra vida.

La vida es definida como la capacidad que disponen los organismos animales y vegetales de realizar funciones que le permiten durar mucho tiempo, sin embargo, la vida consiste en la autoorganización de una guía que define su estructura y procesos. Es decir, la actividad que presentan los organismos conformados por células. Por lo que un ser vivo es también considerado como un organismo, pues es un conjunto de moléculas que forman una estructura organizada y compleja, en donde intervienen moléculas, que se relacionan con el medio ambiente en un intercambio de materia y energía y esto permite desempeñar las funciones básicas de la vida como la nutrición, el metabolismo y la reproducción, de tal manera que actúan y funcionan por sí mismos sin perder su conformación.

Los sistemas autopoiéticos y homeostáticos buscan mantener su propia identidad sometiéndose a cambios relacionados a su entorno con la finalidad de mantener una identidad propia. Estos sistemas mantienen una organización propia a partir de como están compuestos y así equilibrar homeostáticamente una relación estática o dinámica entre procesos. Retomando que los seres vivos estamos formados por 4 tipos de moléculas basadas en biomoléculas conocidas como carbohidratos, lípidos, proteínas y ácidos nucleicos, así como también de moléculas inorgánicas como sales minerales, que son átomos para nuestro funcionamiento celular.

Como fue mencionado, los seres vivos están compuestos por células y según su estructura puede ser eucariota en donde su material hereditario, es decir ADN esta encerrado dentro de una  membrana que delimita un núcleo celular  y procariota que no tiene núcleo celular y su ADN no esta aislado dentro del núcleo sino del citoplasma.

Finalmente, existen teorías que comprueban que estamos compuestos por organismos, moléculas, biomoléculas y células, por ende, la vida de cada ser humano reacciona de manera única debido a que cada metabolismo es dependiente de un ADN basado por distintos procesos y materias.

DO YOU KNOW ALL THE SYMPTOMS OF COVID-19?

 

SHORTNESS OF BREATH.

COVID-19 causes shortness of breath, it is usually one of the main symptoms because this potentially deadly virus attacks the lungs, which causes a deficiency in the functioning of the down. The patient who suffers from the symptoms can suffocate quite regularly and even the patient who is asymptomatic can suffer from it less frequently.

As this symptom has been detected, the patient can do small breathing exercises, that is, blow into a bag, take short breaths for 30 seconds and among others. Because you can lose control of your breathing by making a smooth movement, this is why there have been cases where patients need oxygen.


In the long term, it can be dangerous because the patient may be dependent on oxygen.

 

FATIGUE.

Researchers at the University of Leeds (UK) have identified a long-term pattern of symptoms that people who were hospitalized with the COVID-19 infection are likely to experience.

The most frequent symptom was fatigue.  More than 60% of the people who had been treated in a ward reported fatigue and a third of them described it as moderate or severe. For patients who had been in intensive care, 72% reported fatigue. Of them, more than half said it was moderate or severe.  

People with COVID 19 present fatigue as one of the main signs of this disease due to the weakening of the immune system that causes a general imbalance of other vital functions.

RUNNY NOSE.

Among the symptoms of COVID-19, there is a runny nose and it is particularly one of the most recurrent among the victims of this virus. At the same time, it causes the nose to turn a reddish color.

 

If you suffer from allergies, it can be a very complicated situation for the patient since they should not be exposed to outside and they will be kept in an isolated room. It will not have ventilation to avoid outside contact to the room.


WE MUST NOT CONFUSE RUNNY NOSE WITH ALLERGIES, for more information see the following video.

FEVER.

Fever is, in fact, one of the most common. In practically all the positive cases for CORONAVIRUS, the patient showed this symptom according to the data available to the National Health System.

fever during the illness is an indication that the body has activated the immune system to fight the pathogen, in this case fevers of 37 ° onwards occur.


PNEUMONIA.

COVID-19 can start with pneumonia, it is an infection that inflames the air sacs of one or both lungs. The air sacs may fill with fluid or pus (purulent material), leading to a cough with phlegm or pus, fever, chills, and shortness of breath. Various microorganisms, such as bacteria, viruses, and fungi, can cause pneumonia; however, in this case, it is due to COVID-19.

Pneumonia can range in severity from mild to life threatening.

As the disease progresses, it may have complications that must be taken care of immediately by a doctor, who will prescribe the corresponding antibiotics.

COUGH.

Coughing is one of the most common symptoms of Coronavirus (COVID-19).Coronavirus cough is dry, persistent, and can leave a person short of breath.  That's because the disease irritates the lung tissue.

People may be coughing due to another condition not caused by the new coronavirus.  A wet cough involves phlegm that moves from the lungs and lower airways into the mouth.

A dry cough, such as that caused by COVID-19, does not produce phlegm.  It usually starts at the back of the throat and produces a barking sound.

 

DIARRHEA AND NAUSEA/VOMITING.

It is rare but possible that patients infected by the virus present these symptoms, however, they usually have it at the beginning of the conditions as if their body indicated that they should be alert.

It usually presents disgust or the feeling of nausea, later if an annoying factor is found, it can generate vomiting. On the other hand, you may only have diarrhea accompanied by severe pain in the abdominal area.

He recommends that the patient be hydrated and positioned in the fetal position to relieve pain.

In case of complications, you should see a doctor immediately.

 

SORE THROAT.

If you do get COVID-19, you won't necessarily have all of the above symptoms.  And some will manifest themselves stronger than in other patients.  The important thing is to know how to identify them, especially a sore throat, which although it can be announced with an itch, inflammation, irritation and redness, but how to associate this last symptom with the Coronavirus and not confuse it with any other disease.

 Dr. Manuel Menduiña Guillén, specialist in internal medicine and member of Doctoralia in Spain, explains that the sore throat of COVID-19 is accompanied by a dry cough, if the latter does not occur, the first discomfort can be attacked from otherwise and should not be associated with the Coronavirus.  In addition, patients infected with the new virus have agreed that they have difficulty eating due to the pain they present.

 


 

LOSS OF SMELL/TASTE.

This symptom can last the rest of the patient's life depending on the severity with which it resided in his body, on the contrary, it will only present the first days in an intense way and as the days go by it will return to normality.



if you have these symptoms, you should see a doctor.

 

HEADACHE.

Headache is one of the manifestations of infection by the new coronavirus, SARS-CoV-2.  Some medical organizations consider it the third most frequent global symptom and the features that differentiate it from other types of headache, the implications on the prognosis and the most effective treatments are becoming better known. The specific headache associated with Covid-19 It is characterized, above all, by the following features:

·         It gets worse with exertion.

·         Increase with head movements.

·         It can wake the patient at night.

·         It is oppressive in character.

Its location is variable.  In patients who already suffered from headaches before contracting Covid-19, aggravation of pain is common.

BONE PAIN.

Bone pain during Covid-19 disease is an unlikely symptom, and even reserved for patients with advanced disease.  Arthritis could be one of the causes of the presence of these symptoms during the condition.  The pain becomes strong and increases with effort, it can cause immobility of small joints and, it is being studied if it causes secondary damage to the disease


Did you know that many of the patients with COVID-19 are asymptomatic?

Of the 734k confirmed cases of patients with COVID-19 in Mexico, more than 50% of those are asymptomatic, according to data from the infobae.

Some infected people never develop symptoms. And these cases can be considered truly asymptomatic.

However, the experience of some physicians has convinced them that many people have rather minimal symptoms. "They don't even notice them, but for some reason they get tested and come out positive (for the coronavirus)," says Luis Ostrosky, an epidemiologist and infectious disease specialist at the University of Texas at Houston.

Remember, COVID-19 is not a government invention. The symptoms of COVID-19 are real and the complications they produce are real too.

AND NOW, WHAT WILL HAPPEN?

The coronavirus came into our lives to teach us an important lesson.

One day, your life may totally change and you will have to adapt to that change.

Before the pandemic came into our lives, we had the ability to do anything that came to mind.

Unfortunately, we didn't know how to value what we had.

However, this situation is not to be regretted. It is a new opportunity to change our lifestyle, making use of the health measures that the government indicated to us at the beginning.




AM I A "QUARENTEEN"?

One of the changes that the pandemic brought with it, is that people must be quarantined.

Being in quarantine, we have to carry out all your activities from home, while we make use of technology.

Some of these activities are homeschool and teleworking. 



Thanks to this new modality, people have adapted new words to their language, like "quaranteen". 

"quaranteen" refers to an adolescent who is in quarantine. 

Are you a "quarenteen"? 











ALL THE INFORMATION THAT YOU NEED TO KNOW ABOUT "COVID-19"

Nowadays, we are living in a complicated situation. This situation transformed our daily life, our way of thinking, and our way of seeing the world. And the most important thing, we never imagined that a pandemic would be the reason for this change. 


Don't you think it's incredible?


Did you ever think that you would have to be quarantined?


Possibly no one imagined that a Virus would come into our lives to change everything. 

Next, we will introduce you to the cause of this change.






As SARS-CoV-2 spread both inside and outside China, it infected people who have had no direct contact with animals. That meant the virus is transmitted from one human to another. It's now spreading in México and around the globe, meaning that people are unwittingly catching and passing on the coronavirus. This growing worldwide transmission is what is now a pandemic.
