alveolar gas dynamics

Alveolar gas dynamics refer to how oxygen and carbon dioxide move between the lungs and the bloodstream. When you breathe in, oxygen enters the tiny air sacs called alveoli, where it diffuses into your blood to be used by your body. At the same time, carbon dioxide, a waste gas from your metabolism, moves from the blood into the alveoli to be exhaled. This exchange depends on differences in gas concentrations and pressures, ensuring your body gets the oxygen it needs while removing carbon dioxide efficiently.
