Question

Significance of Diaphragm.( class 10 ncert) ​

Answer 1

• The diaphragm is the primary muscle used in respiration.
• This dome-shaped muscle is located just below the lungs and heart.
• It contracts continually as you breathe in and out.
• It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs.
• When you exhale, the diaphragm relaxes and the air is pushed out of lungs.
