as much to be learned and explored. From straightforward dissections to the classical conditioning experiment by Pavlov, scientists used substances in the bodies of animals to invent vaccines and create pills for diseases.
             During the age of modern science, vivisection still assists researchers in the search for treatments. The H5N1 avian flu virus required animal experimentation. This year, scientists from National Institute for Biological Standards and Control combined the viruses found in humans and chickens in an attempt to formulate a vaccine.
             The U.S. Department of Health and Human Services estimated that animal research has aid in extending of human life expectancies by 20.8 years. Another instance is where scientists have found that pig fetuses aid the treatment of Parkinson's disease and that alcoholism is related to genetics. Vaccines for polio, infectious diseases such as rubella, measles, and pertussis were also discovered. Furthermore, most of these preventive measures were developed and tested on animals for safety, before applying to humans. This serves as a safety net for human consumption.
             Numerable remedies for present-day ailments and illnesses too have been constructed through vivisection. These prescriptions ameliorated, or at least bridled, the medical conditions of diabetics, cancer patients, and individuals suffering from organ deterioration.
             Surgical and transplantation operations such as coronary artery bypass grafts, retinal reattachments, and liver, heart, lung, and kidney transplants evolved from experimenting corrective procedures on animals. Scientists have also learnt about the basis of relieving pain, coping with cardio attacks, feeding intravenously, and discovered chemotherapy for cancer treatment. In
