Question

Which of the following is not a function of the respiratory system?
A)Assists with homeostasis of body pH
B)Distributes oxygen to cells
C)Filters air
D)Warms air

Accepted Answer

Distributes oxygen to cells is not a direct function of the respiratory system; it is primarily the function of the circulatory system. The respiratory system is responsible for the exchange of gases (oxygen and carbon dioxide) between the air and the blood, but the distribution of oxygen to cells throughout the body is carried out by the circulatory system.
