Role of chemical and process engineering in the solution of particular problems of physiology

The tools characteristic for chemical engineering approach for modelling of complex phenomena of nature, were used for analysis of transport processes in the human lungs. Mechanics of breathing, air flow structure in the resp iratory system and aerosol particle deposition for drug delivery via inhala tion is presented. The defence mechanism for removal of deposits from the r espiratory system and their quantitative analysis is formulated. Finally, t ransport of oxygen from the external atmosphere into the blood system is de scribed.
