What is the diaphragm and its role when you are breathing?

The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges.

Explanation:

A diaphragm is a large dome-shaped muscle under the lungs that squeezes downward when you breathe in, making a vacuum that causes a rush of fresh air into your lungs. i hope this helps!

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
