What Are the Functions of Blood? - tradutor de inglês

O sangue desempenha um importante papel no organismo, quer seja transportando ou trazendo os elementos essenciais a vida. A seguir para vc praticar seu inglês trago este texto simples e informativo com palavras fáceis e um tema bem pertinente para os dias de hoje, quais são as funções do sangue? Bom aprendizado!


The functions of blood are numerous but can essentially be broken down into two subsets. Blood transports things to the various tissues of the body, and it removes things from the tissues of the body. It may be easiest to think of blood as a never-ending series of light rail cars or trains that travel through an immense transportation network. In this sense, the "cars" are constantly either delivering needed elements or carrying away things produced by the body.


As a delivery system, there are numerous functions of blood. Key among these is to deliver oxygen to all tissues, since no area of the body survives without a regular supply of oxygen. This is not the only thing on the "light rail system" that gets delivered, however. Other things that travel in blood include hormones, nutrients, temperature regulating elements, and various forms of nourishment, such as minerals and vitamins.

Certain types of blood cells go into action only if the body requires it, and this is one of the major functions of blood. If bacteria enter the body, white blood cells arrive to fight it. An injury requires cells and materials to help clot blood. These cells are not apart from the rest of blood and are constantly traveling with it. Looking at a cut bleeding, people can’t see the cells as different, but under a microscope, it's easy to see there are many elements that make up blood. By all of these elements traveling together, they are ready to work in the ways needed when required, and these additional "as needed" functions could be called special deliveries, based on individual bodily circumstances.

It's thus clear that one of the functions of blood is to work as a delivery system, but the transportation network has another important job. It also needs to be able to clear away things the body produces or doesn't need. Various types of waste are carried away by blood and may ultimately be excreted from the body or transformed through chemical processes. Blood must also get rid of excess carbon dioxide so that blood levels retain a normal pH balance.

When the functions of blood are suspected as being insufficient or abnormal, one thing doctors may do is perform a complete blood count (CBC) test or other medical tests to determine the efficacy of the cars and the network. Doctors could for instance look at veins and arteries to see if narrowing is creating problems with the "cars" traveling. Alternately, they could look at the blood itself to check it for insufficiencies. Since so much of what bodies are able to do is fully dependent on this vital transportation system, problems with it can be become hugely important and require immediate repair or medical treatment

29 de agosto de 1958 - 25 de junho de 2009

Michael Joseph Jackson died at age 50 in Los Angeles on June 25, 2009. He spent a lifetime surprising people, in recent years largely because of a surreal personal life, lurid legal scandals, serial plastic surgeries and erratic public behavior that have turned him -- on his very best days -- into the butt of late-night talk-show jokes and tabloid headlines. But when his career began to take off nearly four decades ago as a member of the pop group the Jackson 5, fans and entertainment industry veterans recognized something else about the pint-size musical dynamo that was unusual: He was in possession of an outsize, mesmerizing talent.

The introduction to his Rock and Roll Hall of Fame entry seemed apt as a global audience followed reports of his hospitalization and then death:
"Michael Jackson is a singer, songwriter, dancer and celebrity icon with a vast catalog of hit records and countless awards to his credit. Beyond that, he has transfixed the world like few entertainers before or since. As a solo performer, he has enjoyed a level of superstardom previously known only to Elvis Presley, the Beatles and Frank Sinatra."
