Question

Which of the following is NOT a function of the respiratory system?
A) Olfaction
B) Taste
C) Production of chemical mediators
D) Voice production
E) Regulation of blood pH

Accepted Answer

Taste is not a function of the respiratory system; it is a function of the gustatory system involving the taste buds on the tongue. The respiratory system is involved in olfaction (sense of smell), production of chemical mediators (such as surfactant), voice production (via the larynx), and regulation of blood pH through the exchange of gases (CO2 and O2).
