Answer

Brief Explanation:

The main function of the respiratory system is gas - exchange (taking in oxygen and expelling carbon - dioxide). It also helps in heat balance and is involved in the production of sound and speech as air passes through the vocal cords. Hormone secretion is not a function of the respiratory system, nor is prevention of disease, muscular support, or passage for ingesting food.

Answer:

The respiratory system allows for gas exchange, water and heat balance, and production of sound and speech.
