Exercitatio anatomica de motu cordis et sanguinis in animalibus

"Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus," commonly referred to as "De Motu Cordis," stands as the seminal work of the esteemed physician William Harvey. Originally published in 1628, this treatise represents a pivotal moment in medical history, as it definitively established the concept of blood circulation throughout the human body. Harvey's achievement in merging meticulous observation, experimental inquiry, precise measurement, and bold hypothesis forms the cornerstone of physiological inquiry. "De Motu Cordis" represents a paradigm shift in scientific methodology, offering a comprehensive exploration of the impact of ligatures on blood flow. Moreover, Harvey's groundbreaking assertion of a "double circulation" system fundamentally reshaped the understanding of cardiovascular physiology. According to his doctrine, blood undergoes a continuous journey, propelled from the heart to the body's extremities, then redirected to the lungs before returning to the heart to complete its circuit. Harvey's revolutionary insights not only captivated the scientific community of his time but also exerted a profound and enduring influence. Indeed, contemporaries such as Thomas Hobbes lauded Harvey as a singular figure, whose teachings were embraced and disseminated during his lifetime, heralding a new era in medical understanding.
