A. To maintain balance in the body
B. To eliminate waste products
C. To exchange gases with the environment
D. To regulate body temperature

Answer:

The main function of the respiratory system is C. To exchange gases with the environment.

The respiratory system plays a crucial role in our bodies by facilitating the exchange of gases between our body and the environment. This process allows us to inhale oxygen, which is essential for cellular respiration and energy production, and exhale carbon dioxide, a waste product generated by our cells.

Without this vital function, our cells would not receive the oxygen they need to survive, and toxic carbon dioxide would build up in our bodies, leading to serious health issues. The respiratory system ensures that our bodies maintain a healthy balance of gases through the process of breathing.

By understanding how the respiratory system works, we can appreciate the intricate mechanisms that allow us to breathe effortlessly and be grateful for the amazing capabilities of our bodies.
