Describe the muscle movement during breathing and how the air pressure changes
During inhale , diaphragm contracts and flatten , intercostal muscles move out & up, which cause the air pressure in the lungs decrease . During exhale, diaphragm relax and goes up. Intercostal muscle moves in & down, which cause the air pressure in the lung increase.
