,Functions of the Respiratory System
• Provides for gas exchange—intake of O2 for delivery to body
cells and removal of CO2 produced by body cells.
• Helps regulate blood pH.
• Contains receptors for the sense of smell, filters inspired air,
produces sounds, and excretes small amounts of water and he
