Answer for screen readers
The primary function of the respiratory system is to intake oxygen for the body's use and to expel carbon dioxide, a waste product.
More Information
The respiratory system's primary task is crucial for cellular respiration, where oxygen is needed to produce energy, and carbon dioxide is a byproduct of this process.
Tips
A common mistake is to think of the respiratory system as only facilitating the intake of oxygen, without giving equal importance to the expulsion of carbon dioxide.
