Explanation:

When you inhale, your lungs expand to hold the incoming air. How much air they hold is called lung capacity and varies with a person's size, age, gender and respiratory health. The maximum amount of air an average adult male's lungs can hold is about six liters (that's the same as about three large soda bottles).

Answer:

When the diaphragm muscle contracts, its dome shape is flattened and the chest cavity gets bigger. This change in the volume of the chest cavity pulls air into the lungs, and they expand. When the diaphragm relaxes, it moves back into its dome shape. When this happens, the chest cavity gets smaller and you breath.
