WebA mathematical modeling of pulmonary gas exchange in human respiratory system Author: Endalew Getnet Tsega and V. K. Katiya The main function of the human respiratory system is to take fresh oxygen from air and remove waste carbon dioxide from blood. There are millions of alveoli in the lungs which are enveloped by network of capillaries.
