Explain how the diaphragm aids in breathing.


Sagot :

Final answer:

The diaphragm aids in breathing by changing the chest cavity volume to facilitate inhaling and exhaling.


Explanation:

The diaphragm aids in breathing by contracting and relaxing to change the volume of the chest cavity. When the diaphragm contracts, it increases the chest volume, lowering air pressure inside the lungs, allowing air to rush in. Conversely, when the diaphragm relaxes, chest volume decreases, increasing air pressure in the lungs, leading to air flow out.
