Modeling the Pulmonary Gas Exchange in Human Respiratory System
The human respiratory system is responsible for taking in fresh oxygen and expelling carbon dioxide. Inhaled oxygen enters millions of alveoli which are enveloped in a network of capillaries. The diffusion of gases take place across the respiratory membrane, where the oxygen from the alveoli moves to the blood in the capillaries and carbon dioxide in the blood of capillaries moves to the alveoli. The partial pressure gradient of each gas allows them to diffuse between membranes. In this study we created a mathematical model for pulmonary gas exchange and a simulation was performed for normal cardiorespiratory parameters responses in a healthy human adult at rest.
