Diaphragm is a cartilage which is present under the lungs. When we breathe in, the diaphragm moves down. This makes air space and air gets in. When we exhale, the diaphragm moves up and the air is pumped out.

Answer 2

The diaphragm is the primary muscle used in respiration, which is the process of breathing. This dome-shaped muscle is located just below the lungs and heart. It contracts continually as you breathe in and out.
