Medical Research with Animals

  Researches indicate that when someone is born nowadays in the USA, has the life expectancy into their 70's, but if the same person was born at the beginning of the 20th century, his or her life expectancy would be only into their 40's. 
  Some aspects have contributed for this evolution, like the better quality of alimentation and learning better forms to keep outselves and envoironment clean, but a vital factor to this huge progress was the research made with animals for medicinal experiments.

What is medicinal research that uses animals?

  Many diseases can infect both animals and humans. So, if we need to test and experiment some medicines to combat these deseases is possive to do this in animals instead of in humans. And the results and information earned from these researchs benefit lots of humans and animals.

How do scientists decide to use animals in medicinal research?

  Medicinal experiments in animals are part of a carefully planned medicinal research. But every experiment in which animals are used, need some considerations before the approval of it.
  The most relevant consideration is that the research must be relevant to humans or animals health. But the animals wellare needs to be protected in every study. That means that the number of animals used in  this studies has to be as low as possible, and the have to be treated humanely in the least cruell way.
