Question

Chest movements are inconspicuous during

• A. Normal breathing
• B. Thoracic breathing
• C. Abdominal breathing
• D. Both(A) and (B)

Answer 1

The correct option is C

Abdominal breathing

Thoracic breathing is the drawing of minimal breath into the lungs, usually by drawing air into the chest using the intercostal muscles rather than through the lungs via the diaphragm. Contracting the diaphragm, a muscle located horizontally between the chest cavity and stomach cavity, leads to abdominal breathing. Air enters the lungs and the belly expands during this type of breathing.The diaphragm is crucial for normal breathing.
