Detailed explanation-4: -The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.

Detailed explanation-5: -What are the main functions of the respiratory system? The important functions of the respiratory system include-inhalation and exhalation of gases, exchange of gases between bloodstream and lungs, the gaseous exchange between bloodstream and body tissues, olfaction and vibration of vocal cords.
