A treatise in three books by the physician of Marcus Aurelius on the powers by which living bodies grow, nourish themselves and generate. Galen argues, against the atomists and the school of Erasistratus, that nature acts purposively and that each organ has specific faculties of attraction, retention, alteration and expulsion. He explains digestion, the making of blood in the liver, the work of the kidneys and the bladder, and defends his views with experiments on animals, including tying off the ureters. The book fixed the physiology that Harvey overturned fifteen centuries later.
