1. What is the primary inspiratory muscles?Diaphragm and external intercostal muscles
2. What is the physiological role?Essential for aerobic respiration, ATP production, and acid-base balance via CO2 elimination
3. What happens inside your body when you take a big breath?Your diaphragm flattens and moves down, and your ribs lift up and out, making your chest bigger. This lowers the pressure inside your lungs, so air flows in until the pressures match.
4. Why is breathing important for playing and growing?Breathing brings oxygen into your blood, which cells use to make energy. It also helps keep your blood’s pH balanced by removing carbon dioxide.

Thoracic Cavity: The space within the chest containing the lungs, heart, and major blood vessels.
Intra-alveolar Pressure: The pressure within the tiny air sacs (alveoli) of the lungs.
Aerobic Respiration: The metabolic process that uses oxygen to generate energy (ATP) from glucose.
