Which of the following anatomical sequences represents the part of the human respiratory system responsible for clearing inhaled air from foreign particles, humidifying it, and bringing it to body temperature?

Step-by-step solution

According to NCERT, the part starting with the external nostrils up to the terminal bronchioles constitutes the conducting part of the respiratory system. The conducting part transports atmospheric air to the alveoli, clears it from foreign particles, humidifies it, and brings the inhaled air to body temperature. The respiratory bronchioles and alveoli form the respiratory or exchange part of the respiratory system, not the conducting part. The incomplete cartilaginous rings extend only up to the initial bronchiole
