WebWith modeling of exactly the same problem but this time reducing blood flow in one “alveolus” by 90%, rather than reducing ventilation as in Figures 5-6 and 5-7, inequality would still be present and both gases would be affected, but because the abnormal “alveolus” has a high and not low ratio, the quantitative effects are different: CO 2 is … Web30 jul. 2024 · Internal respiration is the exchange of gases with the internal environment, and occurs in the tissues. The actual exchange of gases occurs due to simple diffusion. Energy is not required to move oxygen or carbon dioxide across membranes. Instead, these gases follow pressure gradients that allow them to diffuse.
