Heart development, also known as cardiogenesis, refers to the prenatal development of the heart. This begins with the formation of two endocardial tubes which merge to form the tubular heart, also called the primitive heart tube. The heart is the first functional organ in vertebrate embryos.
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 ...
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 ...
He wrote around 14 books on his findings in anatomy, including his best known book De humani corporis fabrica. [11] It was revolutionary because of the accuracy and precision of his descriptions and images of organs and would refute Galen 's belief that human anatomy is closely related to apes. [ 14 ]
Werner Theodor Otto Forßmann (Forssmann in English; German pronunciation: [ˈvɛʁnɐ ˈfɔʁsˌman] ⓘ; 29 August 1904 – 1 June 1979) was a German researcher and physician from Germany who shared the 1956 Nobel Prize in Medicine (with Andre Frederic Cournand and Dickinson W. Richards) for developing a procedure that allowed cardiac catheterization.
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature.
As early as the 1930s, it was known that small electric shocks could induce fibrillation in the ventricles of the heart, and that more powerful shocks could reverse this fibrillation. In 1947, Claude Beck (1894 – 1971) reported the first successful internal defibrillation of the human heart.
It notes that the heart is the center of blood supply, and attached to it are vessels for every member of the body. The Egyptians seem to have known little about the function of the kidneys and the brain, and made the heart the meeting point of a number of vessels which carried all the fluids of the body—blood, tears, urine, and semen.
