The phrase "animal used for scientific purposes" refers to animals that are specifically bred, raised or captured for the purpose of being used in research and experimentation. These animals may be used in a variety of ways depending on the specific needs of the scientists conducting the study. They can serve as models for human diseases, help develop new treatments, test the safety of drugs, cosmetics, and other products or provide insights into animal behavior and biology. The use of animals in scientific research is carefully regulated to ensure their well-being and minimize any discomfort or pain they may experience during the process.
