Explanation:
Detailed explanation-1: -The diaphragm is the main muscle used for breathing. The muscles between your ribs: Called intercostal muscles, these muscles play a role in breathing during physical activity. Abdominal muscles: You use these muscles to help you breathe out when you are breathing fast, such as during physical activity.
Detailed explanation-2: -The breathing muscles This change in air pressure means that air is ‘sucked’ into the lungs on inhalation and ‘pushed’ out of the lungs on exhalation. The intercostal muscles between the ribs help to change the internal pressure by lifting and relaxing the ribcage in rhythm with the diaphragm.
