C) Temperature regulation of air D) Diffusion of CO2 and O2

Answer 1

option D..............

Answer 2

Answer:

Diffusion of CO₂ and O₂ is not the function of the conducting zone of the human respiratory system. (option d)

Explanation:

• The respiratory system is a network of organs and tissues that help in the process of inhalation and exhalation.
• The conducting zone of the respiratory system is the part that transports the air to the alveoli.
• Since the air we breathe contains numerous impurities, the conducting zone removes and clears the foreign particles in the air, humidifies it and also brings it to the temperature of the body. Finally, it is transported to the alveoli.
• The diffusion of CO₂ and O₂ takes place in the alveoli, which is the exchange zone.
• They are the tiny sacs in the lungs, where the exchange of O₂ and CO₂ takes place.
• The capillaries in the alveoli walls help the O₂ and CO₂ move.
