Solution:
Additional muscles which impact the ability of humans to increase the strength of respiration are found in the abdomen. This is due to the fact that we can voluntarily take deep breathe by an effort. In the process of deep inspiration or expiration, chest distention is brought about by the external intercostal muscles and the abdominal muscles.
