WebMar 16, 2024 · As oxygen moves out of the alveolus, CO 2 molecules pass into it. Then, they are breathed out of your body through your nose or mouth. Alveoli are lined by a fluid (surfactant) that maintains the shape of each air sac and helps keep it open so oxygen and CO 2 can pass through. Your diaphragm is the muscle that controls your breathing. WebN2 is so inert that it can diffuse freely across membranes and dissolves into fluids throughout the body. This means there's a net outflow of N2 from the capillaries to the alveoli, which balances the gap in pressures between O2 coming in and CO2 going out.
