Human Physiology is the science that studies how the human body and its parts function.
Between the 16th and 17th century, Santorio Santorio (1561-1636) – a physician friend of Galileo Galilei – and the Englishman William Harvey (1578-1657) both found themselves in Padua.
Santorio, starting from his recent discoveries in Physics, designed several instruments of physiological measurement and was the first to introduce quantitative measurements in Medicine. Harvey was the first to discover that blood circulates inside the body, contrary to what the Greek scientist Galen used to affirm.
Among the developments of modern Physiology, we must remember Phrenology, which studied the psychic functions of the individual by associating them to the brain areas and the shape of the cranium.
