HEART / the motor of the life

 The body is composed of a careful and smart system, each system is composed at the same way, of organs with specifics works and functions; the organs are composed of tissues, and the tissues, ending the idea, are composed of cells. So, the cell is wonderfull; in it, all the metabolic reactions have place, all the reactions what make possible the life occur in the cell.
 As I write, the cells make issues and the issues makes organs. Let's talk about they.
All the organs are important, except the appendix; because her function is unknown, but I think if is a organs, must have a function. One of the most incredibles and importants organs in the body is, for me, the heart. Is like a motor in the body, make all the rest of the organs turn on and never sleeps; a heroe.
 The heart is localizated in the chest, in the left side of the body. Resently, in a nature paper; scientist explain why the heart is in the left side and not in the right, the actual theory says that happen because when the human is in gestation, when the cells are building the heart, they moves more of the right side, pushing the organ for the left side of the chest. The position of the heart it's perfect for connect all the parts of the body; he is something like the boss of the circulary system.
 The roles of the heart are generating blood preassure, routing the blood, separates pulmonary and circulary systems, ensuring one-way blood flow; heart valves ensure one-way flow, regulate the blood suply and change the contraction rate and force match blood delivery to changing metabolic needs, and others.
The size of the human heart is 12 cm of large, 9 cm of widht and 6 cm of thickness; the scientist says the size of the heart if the same of the closed fist of each person.
The illness can affect the heart are; high preassure; one of the most principals and typical nowadays; high preassure make stroke, sexual disfunction, vision lost, heart attack, heart failure and others, and the obesity, fat diet, smoke and sedentary lifestyle can affect really seriously the heart.
For make the heart healthy and working perfectly we can have a healthy diet, with a lot of proteins, eat a lot of vegetables and fruits, drink water, sport, and care aggainst the fat food, like fastfood and fry. This is so important, because if we don't care our health, all the organs work bad and that make diseases.

Hi Guys! How you doing? Back to the little vacations we have. Today I'm gonna talk about future jobs. I decided to study biochemistry because it's one of this career what, when you graduate of it, can work in a lot of places, you can investigate, be a teacher of university; or maybe high school if you want, work in a laboratory, you can be a businessman, or businesswoman I don't know, you can discover about everything about science. As a biochemist, you can work in molecular biology, in medicine and health, in neuroscience, in chemistry and, of course; in biochemistry. I would like to work in molecular biology, as a investigator; I love organism called "extremophiles", I think it's a interesting area, not to popular, but so important for the science. I imagine working in the laboratory, of course; investigating and discover new things about this incredible organisms; but at the same time, I imagine working in ground,I mean, searching this organisms in their...

WHY I STUDY WHAT I STUDY

The science, a big word. That it's all. The science it's, from the beggining, the true behind all we can see. I think that it's the main reason of study biochemistry. But not always was to study Biochemistry. When I was a child, my dream was to be an astronaut; that is so cliche, but I like the idea of explore the universe, know things about our origin. When I was in High School, my dream changed, now I wanted to be a doctor, I like the idea of help the people, study the human body, study the life, the anatomy of the body. In the last year of High School, everything change; I understand the reality of be a doctor; and I don't like it. So, I have a year for find my road. I just know one thing; I like science. What can I study in science? My favourite subject in the high school was biology, second; the chemistry. What I do in that? Suddenly, all was clear. I met biochemistry. At the moment to apply to university, my first option was the Universidad de Chile. I wa...
