Explanation
When humans respire, gaseous exchange process occurs in which we inhale oxygen (O2) into the lung and exhale Carbon dioxide (CO2) out of the lung. In this gaseous exchange system in humans, the journey of gaseous especially Carbon dioxide from a tiny sac in the lungs called alveolus is ordered as follows: Alveolus-Bronchioles-Bronchi-Trachea-Mouth and/or the Nose. Carbon Dioxide is expelled through this sequence. Any disruption in the mentioned sequence will imply the wrong route in which the said gas passes. Thus one will have to study the basic gaseous exchange before orders will be verified.
