Vivisection is the practice of performing surgical operations on live animals for scientific research. It is often used to study biological processes, test new medical treatments, and understand diseases. The goal is to gain insights that can lead to advancements in human and veterinary medicine. The use of vivisection raises ethical concerns regarding animal welfare and rights. Many organizations advocate for alternatives, such as computer modeling and in vitro testing, to reduce the need for animal experimentation. Debates continue about the balance between scientific progress and the humane treatment of animals in research settings.
