Step 1
Atmospheric pressure is the pressure exerted by the weight of the atmosphere, which at sea level is approximately 1 atmosphere (atm) and decreases with increasing altitude. It doesn't directly prevent the lungs from collapsing. Show more…

Assertion: Human breathing is negative pressure breathing. Reason: Air drawn in lungs because of pressure less than atmospheric pressure in lungs during inspiration
During inhalation, _______. a. the thoracic cavity expands b. the diaphragm relaxes c. atmospheric pressure declines d. the lungs deflate
The intrapleural pressure is necessarily lower than the atmospheric pressure during: (A)inhalation, because the expansion of the chest cavity causes compression of the intrapleural space, decreasing its pressure. (B) inhalation, because the expansion of the chest cavity causes expansion of the intrapleural space, decreasing its pressure. (C) exhalation, because the compression of the chest cavity causes compression of the intrapleural space, decreasing its pressure. (D) exhalation, because the compression of the chest cavity causes expansion of the intrapleural space, decreasing its pressure.
