Integrated course unit module: PHYSIOLOGY

Learning objectives

The student should acquire:

-The knowledge of the mechanisms by which the human organism obtains and maintains the homeostasis at level of cell and tissue, the mechanisms of transport and communication and the basal metabolism.
-The knowledge of the functional mechanisms of the human body organs, the knowledge of their dynamic integration in apparatuses and the general mechanisms of functional control in normal conditions and in particular pathological conditions.
-The knowledge of the main functional reports in healthy humans.

Prerequisites

Knowledge of the Physiscs, Biochemistry and Anatomy of the human body.

Course unit content

Cardiovascular apparatus. Physical principles of hemodynamics. Physical properties of blood. Miocardial properties: rhythm, conduction, excitability, contraction. Heart electrophysiology. Ionic theories of resting and action potentials. Electrocardiogram. Heart mechanics and the cardiac cycle. Cardiac output. Intrinsic and extrinsic regulation of heart activity. The vascular system. Passive mechanical properties. Vascular smooth muscles. Nervous and endocrine regulation of blood vessels. Blood pressure; systolic, diastolic, mean and pulsatory. Measuring blood pressure. Venous pressure and blood circulation. Arterial and venous pulse. Coronaric circulation and and heart metabolism. Local circulation: muscle, skin, kidney, splancnic.

Respiratory Apparatus. Physical laws of gases. Chest and respiration muscles. Alveolar and pulmunary ventilation. Lung volumes and capacities. Anatomic and functional dead space. Mechanics of breathing. Intra-pulmunary and intra-pleural pressures. Compliance. Pressure-volume curves. Airway resistance. Work of breathing. Inspirated air, alveolar air, and expirated air. Blood-tissue gas exchange in the lung: relationships between ventilation and alveolar pressures of gases. Distribution of ventilation. Gas exchange between alveoli and capillaries. Blood transport of oxygen and carbon dioxide. Pulmunary circulation. Ventilation-perfusion relationships. Respiratory centers: Genesis of the rhythm of respiration.
