During respiration, gas exchange takes place in the alveoli of lungs.
Explanation:
Alveoli:
These are tiny air sacs within the lungs where the actual exchange of oxygen and carbon dioxide occurs between the blood and the air.
Trachea and larynx:
While the trachea (windpipe) and larynx (voice box) are important parts of the respiratory system, they don’t facilitate the gas exchange themselves. They serve to transport air to and from the alveoli.
Throat:
The throat (pharynx) is also part of the air passageway, but its primary function is not gas exchange.
