The aim of the course is to provide the basic knowledge needed to understand the concepts and their physical methods that are applied to medicine. In particular the student will gain knowledge of some basic physical laws and techniques for the understanding of the physiological processes and will learn the basic concepts useful to the correct use of the equipment used at work. What prerequisites are required basic knowledge of algebra, Euclidean geometry and trigonometry.
