Summary - Medical experiments on animals

Medical research on animals is necessary to understand how living things work and also to test out new cures for a variety of human illnesses, thereby advancing medical science. Two notable achievements resulting from experimentation on animals are an understanding of how the body works - for example, the circulatory system and lung functioning - and cures for fatal illnesses such as cancer and organ failure. While many animals die during research, scientists try to make their existence as comfortable as possible by reducing the number of animals and experiments used and by causing minimal harm to them by using anaesthetics, painkillers and antibiotics.
