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.

HOLY HOLIDAYS

Hi guys! How are you? Today i'm gonna talk about the holidays; that wonderful time to relax and rest of the year.  I think the vacations are so important. For me, this year was amazing but at the same time so exhausting; because the university is not like the school, and this months I live alone, so, that it's a little bit different what I was accustomed.  The holidays, I think I really deserve it!  So, first; I just want sleep and relax, ride in my bike and spend time with my family and my friends. I love the summer, because; for us, what  we live in south america, is in the summer when we celebrate Christmas and the "New Year"; so, at the same time, we have holidays, gifts and summer!  I don't really think what I will do in the summer; but I want to ride in my bike, to cross the forest and breathe fresh air. Of course, I love the beach and I think I will go with my family to our cabin in the beach. I love spend time there because the sea is amazing,...

PABLO VALENZUELA

Hi guys! How you doing? Today I wanna talk about a big person. As you know (I write about in another blog) I study Biochemistry. An today, I'm gonna talk about a big biochemical, and Chilean! His name is Pablo Valenzuela. Doctor Valenzuela studied Biochemstry in Universidad de Chile and is a Doctor in Chemistry in the University of Northwestern (PhD.) In the year 1974 it received the scholarship of the International Scientific Fellow (NIH) and came back to The United States. In 1981 Chiron Corporation fused the biotechnological company, where it clones and it sequenced the genome of the AIDS virus. The most importants investigation are the discovery of the hepatitis C, and the creation of the first vaccine for the hepatitis B. I love the way of Pablo Valenzuela to mix the science and the business. I think his work it's awesome, and is Chilean and study here, in the same University of us! Doctor Pablo is the father of the biotechnology, one of the first man to mix t...

Who am I?

First, my name is Cristóbal Mansilla. I’m from Chile, and now I live in Santiago of Chile, the capital of the country. I was born in Fresia, a little city next to Pto. Montt, and I live there all my life, but I change to study Biochemistry in the University of Chile. I’m a real fan of the science, and now I have the possibility of to go ahead with my curiosity and, in a couple of years, work in that. My interest in the science includes the biology of the living beings to the chemistry behind that life. But I like a lot of other things, like the literature; my favorite book is “The catcher in the rye”, because I’m amazed of the talent of JD Salinger (the author) of describe and write the story of an adolescent with a beautiful timelessness. Of course, I have other hobbies like cycling and watch movies and series.
