Intercostal muscles are muscle between two ribs in our chest region. The constrict to lift ribs and increase the volume of rib cage. Increasing the volume the low air pressure attract air in lungs. So we respire by relaxing these muscles we expire the air out.
The intercostal muscles are the muscles that lie between the ribs and form the chest wall. Their function is to aid inhalation and exhalation.
