Heart 

The organ I decided to talk about is the heart, since children imagine it with a form remote from the real and we believe it is related to feeling, now I know that the feeling are in the brain, although that is much less poetic. The heart is just a blood pump but its functioning is central to the body. 
The heart is a muscular organ (is the central organ of the circulatory system) ,which pump blood through  the blood vessel of the circulatory system. Blood provides the body with the oxygen and nutrient. It is located in the central region of the thorax, between the two lungs. The human heart has the size of a fist, a weight of 300 grams and is made up of heart muscle.
It is divided into four chambers: two upper and two lower. The upper chambers are called atria(left atrium and right atrium). At the bottom are the chambers called ventricles(left ventricles and right ventricles). The heart drives the blood through a movement called systole and diastole.The cardiac cycle is called the combination of a complete systolic and diastole movement.
Myocardial diseases can alter their normal functioning. Some ways to care for the heart is by maintaining a healthy diet, reducing stress and avoiding tobacco consuming.

Study program Hello everyone, how are you? Today's topic is my study program, when our generation enters the university, a new study program is started. All when we enter the university we feel that our subjects are the most difficult and complicated. The truth I do not know what subjects I would change in the study program since I have only been in the university for 2 years and I have not studied so many subjects, also the first subjects are common among the 4 careers of the faculty so I do not know much about the specific subjects of my career. The facilities of the university are good, the laboratories have all the necessary material to carry out the works and learn in the best way, although they could always be better and more modern. The duration of the degree in chemistry and pharmacy is 5 and half years (11 semesters). The academic load is great and every year more time is needed to study. During the first year in the university they could dedicate the weekend...

      My best holidays   It's hard to choose my best holidays, but the most fun are camping holidays on "Lago Rapel".  Every years my family spent a week camping on "Lago Rapel". Since I can remember camping on the lake every summer. It's very funny because my whole family is going.  I always have be hard set up a tent but it's entertaining and I like to try it. I learned to fish in the lake next to my brother and my uncle. On one of those trips to lake my little brother, Benjamin, learned to swim. Every time we go to lake with my family we like to cook a lot, play cards and swim.many people thinks is a uncomfortable sleeping in a tent but I think It's fun and after a long day of doing many things you fall asleep without realizing it. It is already a family tradition to go to the lake in the summer. It is a quiet place to rest and have fun, away from the noise of the cities, enjoy the nature and disconnect a bit of the world to just rest....

My favorite piece of technology Wow it's very difficult to decide which is my favorite piece of technology,but the decision is between my Nintendo 3DS , my kindle or my cell phone. My 3DS bought it after working in the summer, just like my kindle. My cell phone was a gift from my dad. My 3DS is a portable console, it helps me a lot to play when I travel to university every day, I love it because I can play everywhere and it allows me to play my favorite game "pokemon", my kindle also helps me to survive my eternal trips to college, it's an electronic book, it helps a lot because in chile having physical books is very expensive (but it will never be better than a physical book). Finally my cell phone, which is what I use most, it is difficult to imagine all the functions you have, but for what I use is listening to music. My life without them would be different, first my daily trips would be very boring and I would rather not imagine my life without being able to...
