Final answer:
The Pores of Kohn in the respiratory system allow collateral ventilation between adjacent alveoli, enabling equalization of pressure and gas exchange even if some alveoli are blocked or damaged.
Step-by-step explanation:
The function of the Pores of Kohn in the respiratory system is d) They allow collateral ventilation between adjacent alveoli. Collateral ventilation is the phenomenon where air can flow between neighboring alveoli through the Pores of Kohn. This allows for equalization of pressure and gas exchange even if some alveoli are blocked or damaged.
