Breathe out:
When the intercoastal muscle relaxs,the rib cages moves downwards and inwards,the diaphragm will moves up.The volumn of chest decreases and gas pressure increases.The air then breathe out.
Breathe in:
When the intercoastle muscle contracts,the rib cages move upward and outward,and the diaphragm moves down.the volumn of chest then increases and gas pressure decreases.Air then enter the lungs.

Breathing is the movement of air in and out of an organism to supply oxygen and expel carbon dioxide and water. This process is necessary for respiration which extracts energy from carbohydrates such as sugar. In plants, movement of air in and out of the organism usually occurs mainly via holes called stomata in the leaves. A good example of breathing roots occurs in mangroves where the roots are often covered by stagnant muddy water.
