As one exhales, what change in energy takes place between the diaphragm and the air in the lungs?
When one exhales, the change in energy between the diaphragm and the air in the lungs can be explained by the process of breathing.
The diaphragm, which is a dome-shaped muscle located below the lungs, plays a crucial role in the breathing process. During inhalation, the diaphragm contracts, flattening out and moving downward. This action increases the volume of the chest cavity, creating a negative pressure that allows air to rush into the lungs.
As the diaphragm relaxes during exhalation, it moves back up into its dome-shaped position. This reduces the volume of the chest cavity, creating a positive pressure within the lungs. The increase in pressure forces the air out of the respiratory system, leading to exhalation.
So, to summarize, during exhalation, the diaphragm relaxes, which decreases the volume of the chest cavity and increases the pressure within the lungs. This change in pressure allows the air to be pushed out of the lungs.
