Our Amazing Human Body: Heart

Resultado de imagen para heart parts
The heart is the organ the most interest me because it is very important, it pumps blood, and it gives us life.
The heart is a pumping muscle responsible for circulating oxygen-rich blood. There are four chambers inside the heart: the two upper chambers are called atria and the two lower chambers are called ventricles. The heart muscle squeezes blood from chamber to chamber. The heart contains coronary arteries, tubelike branches, which are attached to The aorta (the large blood vessel that carries blood and oxygen from the heart to the rest of the body).


It might be a shocker for some people, but hearts isn’t really located on the left side of the chest. It lies between the right and left lungs, in the middle of the chest and slightly towards the left of the breastbone. In rare cases, the heart is located towards the right side. This condition is called dextrocardia and is congenital in nature.

The human heart is about the size of an adult's closed fist, but the size varies according to an individual's age, health and size, weighs 7 to 15 ounces.

There are many diseases that can alter the normal functioning of the heart, some are: 
Rheumatic heart disease
Hypertensive heart disease
Ischemic heart disease
Cerebrovascular disease
Inflammatory heart disease
And many others.

To keep the heart healthy we can follow these tips:
- Eat healthy fats, NOT trans fats
- Get enough sleep
- Avoid secondhand smoke like the plague
- Sit less and sweat more (exercising).

Summer holidays

The summer is a season for relax and sleep, at least for me my house is a good place for do that, also I really love to watch movies and series, and obviously sleep. Usually during holidays I like to do manual things, like cook, make me nail designs or learn to do things with recycled materials. Now I don´t have any plan or idea for this summer, but with the time they appear. Every summer I go with my parents to the beach, sometimes the whole family goes, and I take care of my cousins, which does not relax me at all, so in that case I prefer to stay in Santiago and see series in my home . I like to go to the north of my country, especially to Coquimbo and La Serena, I really like to eat papayas in those places, and visit Elqui Valley, it's a very relaxing place. Also the Serena beach is very large, so you can see very few people and you can not meet anyone, and in Coquimbo they sell empanadas on the beach, which is the best of that place. Part of my summer "holiday's&q

Hobbies

My favorite hobbie is watch TV series, sleep and play handball. I watch TV series or Netflix in my house, college, where there is internet and have time, also I love sleep, I sleep in everywhere, I’d rather sleep than do something. I also like to play handball, I learned in college and became my new hobbie, it distracts me enough and when I play I think of nothing.  Playing handball in important to me because it relaxes me, and thus I do not think about the problems of the college or any other, perhaps I am not very good playing but I enjoy it.  When I was younger I liked to skate, I spent all afternoon skating on the street or in the park, I also saw series at night and I had fun. The hobbies for me mean to entertain, to send the mind to another side and to forget everything. I’ve never played soccer, I do not like it, I’m very bad at playing with my feet, I think I’ll fall alone or end up kicking other without meaning to.  I don’t think about the future, maybe the only hobbie I’

changes to my study programme

When I entered to study at this university,I thought it would have good infrastructure, that would have large libraries, a good gym, a big place to eat, and things like that .. But I was a little disappointed to see what this faculty had, even though it is better this to nothing. I think that one of the main changes that should be made in the program of study is in the "Introductions to the race", since they do not teach us what an engineer does, or in all the areas that can be worked, could lead us to Factories, to encourage people who enter the race and not drop out the first few months, because they did not get noticed because of what they saw about the things that a food engineer does. The curriculum is very complete, but could have more "advanced" subjects, where we work with food, an example, have a chapter of sensory analysis of food, we are taught only the basics, in the same subject of introduction to the career. It could also have better laboratories for
