Respiratory Regulation

This lecture explores the regulation of breathing through experiments involving changes in oxygen and CO2 fractions, demonstrating the impact on ventilation. By manipulating gas mixtures, the instructor illustrates how the respiratory system responds to varying levels of oxygen and CO2, leading to adjustments in ventilation. The experiments involve breathing different gas mixtures to observe the effects on oxygen and CO2 levels, highlighting the body's compensatory mechanisms in response to altered gas compositions.
