Q. Explain how the process of breathing occurs.



A. When you inhale, your lungs expand and the pressure

inside them becomes lower than the pressure outside your body. Air naturally flows into your lungs to equalize the pressure.

When you exhale, the muscles relax and the volume of your chest cavity decreases, making the pressure in your lungs higher than the pressure outside your body. Air naturally flows out of your lungs to the area of lower pressure.
