Accepted Answer

The primary function of the respiratory system is to take in oxygen (O2) from the air and expel carbon dioxide (CO2), a waste product of metabolism, from the body. This process is essential for cellular respiration, where oxygen is used to produce energy, and carbon dioxide is produced as a byproduct. Options B, C, and D do not accurately describe the functions of the respiratory system.
