To determine the functions of the respiratory system, we need to understand its role in the human body.
The respiratory system primarily functions to facilitate the exchange of gases between the body and the environment. Here are the correct functions of the respiratory system:
1. To deliver oxygen to the body: The main function of the respiratory system is to bring oxygen from the air into the body. This is achieved through the process of breathing, where oxygen is inhaled and transported to the bloodstream.
2. To remove carbon dioxide from the body: Alongside delivering oxygen, the respiratory system also eliminates carbon dioxide, a waste product produced by the cells during metabolism. The respiratory system enables the removal of carbon dioxide by exhaling it out of the body.
Therefore, the correct functions of the respiratory system are:
- To deliver oxygen to the body.
- To remove carbon dioxide from the body.
