William Harvey (1 April 1578 – 3 June 1657) [1] was an English physician who made influential contributions to anatomy and physiology. [2] He was the first known physician to describe completely, and in detail, pulmonary and systemic circulation as well as the specific process of blood being pumped to the brain and the rest of the body by the heart (though earlier writers, such as Realdo ...
In 1651, William Harvey published On the Generation of Animals (Exercitationes de Generatione Animalium), a seminal work on embryology that contradicted many of Aristotle's fundamental ideas on the matter. Harvey famously asserted, for example, that ex ovo omnia—all animals come from eggs. Because of this assertion in particular, Harvey is ...
An experiment from Harvey's Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus. Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (Latin, 'An Anatomical Exercise on the Motion of the Heart and Blood in Living Beings'), commonly called De Motu Cordis, is the best-known work of the physician William Harvey, which was first published in 1628 and established the ...

1628 – William Harvey published An Anatomical Exercise on the Motion of the Heart and Blood in Animals; 1651 – William Harvey concluded that all animals, including mammals, develop from eggs, and spontaneous generation of any animal from mud or excrement was an impossibility. 1665 – Robert Hooke saw cells in cork using a microscope.
The work of Ibn al-Nafis regarding the right sided (pulmonary) circulation pre-dates the later work (1628) of William Harvey's De motu cordis. Both theories attempt to explain circulation. 2nd century Greek physician Galen 's theory about the physiology of the circulatory system remained unchallenged until the works of Ibn al-Nafis, for which ...

William Harvey postulated blood flow as a closed, continuous loop that run throughout body that contained a certain quantity of blood. To test his claim, Harvey dissected human corpses and animals and, based on his anatomical findings, devised a simple demonstration of how arteries and veins continuously carried blood throughout the body.
