Explanation

William Harvey, the English physician, discovered the circulation of blood in 1628 and published 'De Motu Cordis' (On the Motion of the Heart). He demonstrated that blood circulates through the body in a continuous loop pumped by the heart. Edward Jenner developed the smallpox vaccine, Joseph Lister pioneered antiseptic surgery, and 'Jonos Esals' appears to be a fictional/distractor name.
