Chest Breathing Mechanics Quiz

Chest Breathing: Inhalation

• Inhalation occurs when the chest cavity expands, allowing air to flow into the lungs.
• The diaphragm remains relatively still, with intercostal muscles between the ribs contracting to lift the ribcage.
• The increase in thoracic volume results in a drop in internal pressure, drawing in air through the trachea.
• This method is often shallow and can lead to reduced oxygen exchange if used primarily.

Chest Breathing: Exhalation

• Exhalation involves the relaxation of the intercostal muscles and diaphragm, causing the chest cavity to shrink.
• Air is expelled from the lungs as the pressure in the thoracic cavity rises above atmospheric pressure.
• This process may be passive but can also involve active contraction of abdominal and thoracic muscles for forced expiration.

Diaphragmatic Breathing: Inhalation

• Inhalation engages the diaphragm fully, causing it to contract and move downward, which increases abdominal space.
• The downward movement of the diaphragm pushes abdominal organs outward, allowing for deeper lung expansion.
• This method promotes greater oxygen intake and efficient gas exchange in the alveoli.

Diaphragmatic Breathing: Exhalation

• Exhalation involves the diaphragm relaxing, allowing it to rise back to its resting position.
• The reduction in abdominal space pushes air out of the lungs more completely, enhancing carbon dioxide removal.
• This technique can be slower and more controlled, promoting relaxation and reducing stress.
