Body organization: Physiology, levels of organization, structure-function interactions Homeostasis: indoor and outside-liquid-compartments homeostatic mechanisms (positive and negative feedback) Biophysics of the membrane: the plasma membrane, forces driving the transport through the membrane (chemical force, electric force), resting membrane potential, equilibrium potential, passive and active membrane transport, osmosis, tone Nervous system: organization, nerve cells, the genesis of the electrical signals (resting potential, graded potential, action potential), functions of myelin, synapses and synaptic transmission, neurotransmitters, spinal reflexes, simple reflex arc. central and peripheral nervous system Skeletal muscle: cellular and molecular structure, sarcomere, muscle contraction, excitation-contraction coupling, muscle metabolisms Cardiovascular system. Blood: composition, functions, blood groups ABO and Rh system Heart: heart muscle, excitement infarction and impulse conduction (pacemaker cells ritmiche- car, conduction system) cardiac cycle, cardiac output, neural control of cardiac output Circulatory system: forces that regulate the flow of blood, functions of the arterial and venous system, venous return, venous return, capillaries functions (comprehensive exchange-filtration and absorption), blood pressure (systolic-diastolic), nervous control of blood pressure Respiratory system: upper and lower airways, pulmonary pressures, Boyle's law, inhale, exhale, pulmonary ventilation, alveolar ventilation, area composition, respiratory membrane, Dalton's Law, gas exchange at the alveolar level, gas exchange at the tissue level Digestive system: digestion, secretion Hormones and control of metabolism Urinary system and its functions. Regulation of pH.

The student must know the general principles of physics, biophysics, biology, chemistry and mathematics in order to apply them to the functional study of the human body. The student must also know the transport mechanisms through biological barriers and the notions relating to electrophysiology and muscular, cardiovascular, respiratory and renal physiology.

the student is required to attend educational activities. The frequency is checked by the teachers through signature / updated lists provided by the Academic Office. The certificate of mandatory attendance to the teaching course is required to the student to be admitted at the final test.

The oral assessment will assess the level of knowledge regarding the topics covered during the course, the property of language and the ability to establish logical interconnections between the topics studied in this course.
