Answer 2

Answer:

The diaphragm is a structure that actively helps in taking the air out of the lungs.

Explanation:

• The primary muscle used for breathing is the diaphragm, which is situated underneath the lungs.
• It is a large, dome-shaped muscle that frequently contracts unconsciously and regularly.
• The diaphragm flattens and tightens during inhalation, and the chest cavity widens.
• A vacuum is produced by the contraction, drawing air into the lungs.
• Then. the diaphragm relaxes and assumes its dome-like form during exhalation, forcing air out of the lungs.
