Final answer:

Breathing and gaseous exchange are interconnected but have distinct roles in the respiratory process.


Explanation:

Similarity: Both breathing and gaseous exchange are processes involved in respiration in humans.

Difference: Breathing refers to the physical act of inhaling and exhaling air, while gaseous exchange specifically involves the exchange of gases (oxygen and carbon dioxide) between the lungs and the blood.

Mechanism of Exhalation: Exhalation is passive and mainly driven by the relaxation of the diaphragm and external intercostal muscles, causing the chest cavity to decrease in volume, leading to air being pushed out of the lungs.
