Answer
Lungs have small external openings to optimize the exchange of gases, protect from pathogens and debris, and maintain moisture and temperature within the respiratory tract.
Solution
a
Gas exchange efficiency: Small openings increase the humidity and temperature of incoming air, which optimizes the conditions for gas exchange in the lungs
b
Protection: Smaller openings reduce the entry of pathogens and debris, which could damage the delicate tissues of the respiratory system
c
Water loss minimization: Large openings would increase the loss of water through evaporation, which is not desirable, especially in dry environments
Key Concept
Respiratory system optimization
Explanation
Small external openings in the lungs serve to optimize gas exchange, protect from harmful substances, and minimize water loss, contributing to overall respiratory efficiency.
