Animal research involves the use of animals in scientific studies to understand biological processes, test new treatments, and evaluate the safety of products. This research helps scientists learn about diseases, develop medications, and improve medical procedures. Common animals used in research include mice, rats, and rabbits due to their genetic similarities to humans and their short life cycles. Ethical guidelines are in place to ensure the humane treatment of animals in research settings. Researchers must follow regulations that promote the welfare of animals, including minimizing pain and distress. The goal is to balance scientific advancement with ethical considerations, ensuring responsible use of animals in research.
