Question

9. What is a large flat muscle that separates the lungs from the stomach area and that is used in breathing?​

Answer 1

Answer:

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.
