Under what circumstances is it correct to use animals in scientific studies?

Animal research is used for four specific reasons. The goal is to increase our knowledge in the science community, have a better understanding of diseases, figure out solutions or treatments to prevent such diseases from happening, and to believe it or not improve the lives of humans, the environment, and animals! Animals have similar structures in their anatomy and biological processes to humans so by watching how their bodies work can give us the insight needed to protect ourselves if something harmful spreads and how to combat such difficulties to our way of living. Since animals and humans have identical traits in their body’s structure, this mean the same diseases can attack a human just as much as an animal.
