Answer:
The main functions of the respiratory system are supplies oxygen to the bloodstream and removes carbon dioxide from the bloodstream (corresponding to functions I and II, first option).
Explanation:
The respiratory system is made up of the airways —which carry air— and the lungs. This allows the respiratory function to take place, which consists of receiving oxygen (O₂)-rich air and eliminating air with carbon dioxide CO₂ content.
In the lungs are the pulmonary alveoli, structures that are found in relation to the pulmonary capillaries and responsible for gas exchange.
<em>The air that enters the lungs ends up in the alveoli, where the O₂ diffuses to the capillary, oxygenating the blood that passes through it. At the same time, the blood with CO₂ that reaches the capillary passes to the alveoli to be eliminated during expiration.</em>
This is the main function of the lungs and respiratory system, oxygenating the blood and eliminating the CO₂.
<em> The other options are not correct, since </em><u><em>provide nutrients</em></u><em> and </em><u><em>control growth of the body</em></u><em> depend on other systems, such as the digestive and endocrine systems.</em>
