Options
- AOnly 1 and 5 are correct
- BOnly 2 is correct
- CBoth 1 and 3 is incorrect
- DBoth 1 and 2 is correct
Correct answer
A. Only 1 and 5 are correct
Step-by-step solution
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 part is the site of actual diffusion of O2 and CO2 between blood and atmospheric air. The anatomical setup of lungs in thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity.
