Options

  1. AInhaled air is humidified
  2. BTemperature of inhaled air is brought to body temperature
  3. CProvides surface for diffusion of O2{O}_{2} and CO2{CO}_{2}
  4. DIt clears inhaled air from foreign particles

Correct answer

C. Provides surface for diffusion of O2{O}_{2} and CO2{CO}_{2}

Step-by-step solution

External nostrils to terminal bronchioles are called the conducting part of the respiratory system.

It serves the following functions

  • Transports the air to alveoli.
  • Clears foreign particles from the air.
  • Humidifies the incoming air.
  • Brings the air to body temperature.

Providing large surface area is not the function of the conducting part and is done by alveoli.
