Under what internal condition does air tend to flow out of the lungs?
Air tends to flow out of the lungs when the internal pressure of the lungs is higher than the atmospheric pressure. This pressure difference is created by the contraction of the diaphragm and intercostal muscles during exhalation, which reduces the volume of the lungs and forces air out.
