Question

Who first described the circulation of blood to and from the heart?

Answer 1

The circulation of blood to and from the heart was first described by the English physician William Harvey in the early 17th century. His groundbreaking work, published in 1628, was titled "Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus" (An Anatomical Exercise on the Motion of the Heart and Blood in Animals). In this work, Harvey detailed the systemic circulation and the concept that blood moves in a continuous loop from the heart, through the body, and back again. His discoveries laid the foundation for modern cardiovascular physiology.
