Medical advances

For as long as doctors have investigated how our bodies function and how they are affected when we become ill, discoveries in medicine have been made by studying animals. In 1628 William Harvey showed that blood flows through the circulatory system by dissection studies and experiments on living animals. In more recent times, modern medicine has enabled the prevention or treatment of many serious illnesses. The research and development of these discoveries have heavily depended on animal experiments, usually through the painstaking work of many research groups over many years.
