Hello everyone! Today I come to talk about a topic that I know that many of you are curious about, because most of us have grown up watching this kind of "beings" in movies, video games, music videos, etc, and I know that we have asked ourselves the question of whether they exist or not; this question I answer today, below. I hope you enjoy the content.
Hay muchos tipos de zombies, pero primero vamos a hablar de los zombies de la cultura pop, o sea los muertos vivientes, esos que te perseguirían para comerte. Este tipo de zombies en específico es imposible que existan ya que cuando una persona muere, deja de respirar y su corazón deja de latir, por lo tanto el oxigeno y otros nutrientes dejan de llegar a diferentes tejidos del cuerpo y por ende, al cerebro.
¿Podrían existir los "Zombies" en la vida real?
Could "Zombies" exist in real life?
There are many types of zombies, but first let's talk about the zombies of pop culture, that is, the walking dead, those that would chase you to eat you. This specific type of zombie is impossible to exist because when a person dies, he stops breathing and his heart stops beating, therefore oxygen and other nutrients stop reaching different tissues of the body and therefore, the brain.
The brain begins to stop functioning just a few minutes after it stops receiving the oxygen blood supply. It is also important to remember that the brain is responsible for many things, including processing information, so if you try to bring back to "life" a person who has been dead for a while, he will not be able to process anything because the brain is not working, so in that case, a zombie, could not smell, hear, see, or anything!
Another important thing that the brain does is to regulate movement, since it is responsible for sending electrochemical signals to the muscles so that they contract and movement occurs. Without a functional brain, this could not happen. There are cases in which the muscles contract by themselves, without the intervention of the brain, but it would be a very disorganized movement; so it is very difficult for a zombie to stand up and therefore it would be impossible for it to run.
Como pudieron observar es imposible que existan este tipo de zombies, pero aún hay otros que "si existirían" como los que son causados por virus, bacterias, etc. De estos tipos de zombies estaré hablando muy pronto por aquí y espero me lean y les guste mucho el contenido.
Regarding the muscles, for the muscle cells of our body to contract, you need calcium to enter and for them to relax, you need this calcium to come out and for all this to happen, you need energy. In the case of a dead person, calcium can enter, but not get out, because there is not enough energy for the latter to happen, that is why we usually see "stiff" people who have been dead for hours, because their muscles remain contracted. After a day of being dead, the cells relax again, but it is simply because they are decomposing.
As you could see, it is impossible for this type of zombies to exist, but there are still others that "would exist" such as those caused by viruses, bacteria, etc. I will be talking about these types of zombies very soon here and I hope you read me and like the content very much.
