Prerequisites
The student is required to have good knowledege in:
- mathematics, physics, chemistry and biochemistry
- anatomy and histology
this at the level of the courses defined as preliminary to the exam of Human Physiology
Learning outcomes
The course of Human Physiology is finalized to provide the students with a deep knowledge of the main functions of the organs and apparata of the human body as well as their overall relationships in the life of the subject. At the end of the course, the student will be able to understand the functions of an healthy subjects so as to be ready to understand their pathologic alterations.
Course contents
Respiratory function: functional anatomy of the respiratory system; conduction system; air flow control; alveolus capillary membrane.
Respiratory mechanics: respiratory muscles and "chest movements"; intrapleural pressure, intrapleural fluid; changes in intrapleural, intrapulmonary pressure, airflow, lung volume; lung volumes and capacities; pressure-volume curve of lung and thorax; thoraco-pulmonary compliance; tension-length relationship of the respiratory muscles ; mechanical characteristics of the isolated lung; surface tension and surfactant; Laplace's law; respiratory work.
Gas exchanges: partial pressures in respiratory districts; gas exchange at the capillary alveolus level; diffusion of gases; pulmonary diffusion of O2; O2 transport; Hb dissociation curve and Hb affinity for oxygen; myoglobin; CO2 transport; ventilation, dead space, ventilation-perfusion ratio; alveolar air and factors affecting its composition.
Breathing control; genesis of the respiratory rhythm; receptors; respiratory responses to changes in PO2, PCO2 and pH; control of the bronchial caliber.
Teaching methods
The course is organized in hall lessons carried out by PowerPoint presentations and, in addition, with blackboard-based explanations of specific topics. A ‘problem solving’ approach will be sistematically used so as to stimulate active attendance by the students and to obtain a verified comprehension of the overall lessons.
