Our body "the perfection" - Part Two / Nuestro cuerpo "la perfección" - Segunda Parte (Eng/Spa)
Yesterday I started what I believe will be a good series of publications where I intend to talk about some particularities of our body, which at least for me are very striking and to a great extent were the ones that led me to study medicine some years ago. This introductory publication can be found below: Our body "perfection" - Part One.
In this second part I want to mention some curiosities about the functioning of that organ that keeps us alive by fulfilling its function as a pump and that is able to send blood to our whole body through a system of "natural pipes " called arteries. This is the heart. Let's start by talking a little about its structure.
The weight of this organ is between 200 and 350 grams, which makes it a very small organ in relation to the size of our organism, but it is clearly indispensable for life. Basically, it is a muscle with an impressive capacity for contractile function. There is no moment in which it stops working in our lives, except for some eventualities, of course, but these are pathological cases, that is to say, abnormal.
As I said, it is a muscle, or rather, a mass of these, which is called myocardium (myo = muscle / cardium = heart) and has a special conformation at the cellular level that allows it to exercise this work of constant contraction without being exhausted throughout life. Although the latter is relative, because if it were inexhaustible it would not stop beating, obviously, but I say this because under normal conditions it beats for decades constantly without fatigue, not the same thing happens to it as happens with other types of muscles that accumulate lactic acid and generate pain, for example when we exercise constantly.
But, like the rest of the muscles, it has the capacity to enlarge due to exercise, this is something we can see in high performance athletes, that due to the high intensity exercise they perform, their body needs more blood in the muscles, which provides them with glucose for energy production, and once this becomes habitual, for the heart to be able to be in a better position to do its job, it enlarges.
One of the most interesting things about the heart is the ability it has to generate its electrical energy to contract, this is done in a specific point of its structure, which after the formation is dispersed throughout the body of the heart and causes it to contract, we will talk about this later.
Ayer comencé con lo que creo será una buena serie de publicaciones donde pretendo hablar de algunas particularidades de nuestro cuerpo, que al menos para son muy llamativas y en gran medida fueron las que me llevaron a estudiar medicina hace algunos años ya. Esa publicación introductoria la pueden hallar a continuación: Nuestro cuerpo "la perfección" - Primera Parte
En esta segunda parte quiero hacer mención de algunas curiosidades del funcionamiento de ese órgano que nos mantiene vivo al cumplir su función de bomba y que es capaz de mandar sangre a todo nuestro cuerpo a través de un sistema de "tuberías naturales" llamadas arterias. Este es el corazón. Empecemos por hablar un poco con respecto a su estructura.
El peso de ese órgano es de entre 200 y 350 gramos, lo que lo hace ser un órgano muy pequeño en relación al tamaños de nuestro organismo, pero es evidente que es indispensable para la vida. Básicamente es un músculo con una capacidad de función contráctil impresionante. No hay momento en el que deje de funcionar en nuestras vidas, salvo algunas eventualidades, claro está, pero ya son casos patológicos, es decir, anormales.
Como lo dije, es un músculo, o mejor dicho, una masa de estos, que se llama miocardio (mio= músculo / Cardio= corazón) y tiene una conformación especial a nivel celular que le permite ejercer ese trabajo de contracción constante sin agotarse durante toda la vida. Aunque esto último es relativo, ya que si fuera inagotable no dejaría de latir, evidentemente, pero lo digo porque en condiciones normales late durante décadas de manera constante sin fatigarse, no le ocurre lo mismo que ocurre con otros tipos musculares que acumular ácido láctico y generan dolor. por ejemplo cuando hacemos ejercicios de manera constante.
Pero, al igual que el resto de los músculos, tiene la capacidad de agrandarse por el ejercicio, esto es algo que podemos ver en los atletas de alto rendimiento, que por el ejercicio que realizan de alta intensidad, su cuerpo amerita más sangre en los músculos, lo que les provee glucosa para la producción de energía, y una vez que esto se hace habitual, para el corazón poder estar en mejor posibilidad de cumplir su trabajo, se agranda.
Una de las cosas más interesantes del corazón es la capacidad que tiene de generar su energía eléctrica para contraerse, esto lo hace en un punto específico de su estructura, lo que posterior a la formación se dispersa por todo el cuerpo del corazón y hace que se contraiga, de esto hablaremos más adelante.
Nice summary post. Ive been writing about anxiety. During anxiety attacks the heart rate goes up because of adrenaline secretion as one of the physical symptoms of anxiety.
Yes, indeed, which lets us see that the body is intimately related in every part of it. What happens in one organ will always affect another. I will check your blog.
Oh yeah, I'll be really grateful if you do. Hope you are having a nice weekend.

Hi. Interesting topic.
Remember to back up your claims with sources. It's a curation standard.
Ok, perfect. Particularly as a Doctor I only speak from my experience and try to give the information in a very easy to understand way.
But you are right, I will keep it in mind in the next publications, I will put sources that support what I mention in my posts.
Thank you for the comment, I will improve that part. Good Sunday.
