Which of the following explains the mechanism of inhalation? An increase in temperature inside the lungs allows for more oxygen to enter the lungs. An increase in atmospheric pressure creates a pressure gradient that forces air inside the lungs, causing them to expand in volume. An increase in chest cavity volume increases the number of moles of oxygen gas inside the lungs. A decrease in chest cavity volume increases the internal pressure and leads to a decrease in the number of moles of oxygen inside the lungs.
