Options
- AConducting part is responsible for diffusion of O₂ and CO₂ while exchange part is responsible for transport of
- BConducting part is responsible for transport of atmospheric air while exchange part is responsible for diffusi
- CConducting part is responsible for humidification and regulation of body temperature while exchange part is re
- DConducting part is responsible for clearing foreign particles while exchange part is responsible for humidific
Correct answer
B. Conducting part is responsible for transport of atmospheric air while exchange part is responsible for diffusi
Step-by-step solution
The outer pleural membrane is in close contact with the thoracic lining. whereas the inner pleural membrane is in contact with the lung surface. The part starting with the external nostrils up to the terminal bronchioles constitute the conducting part whereas the alveoli and their ducts form the respiratory or exchange part of the respiratory system. The conducting part transports the atmospheric air to the alveoli, clears it from foreign particles, humidifies and also brings the air to body temperature. Exchange p
