Question
Which of the following is a function of the respiratory system?
- absorption of nutrients
- transport of oxygen
- gas exchange
- structural support
Solution
To determine which of the options is a function of the respiratory system, let's analyze each choice:
-
Absorption of nutrients: This is primarily a function of the digestive system, not the respiratory system.
-
Transport of oxygen: While the respiratory system is involved in bringing oxygen into the body, the actual transport of oxygen is a function of the circulatory system, specifically via the blood.
-
Gas exchange: This is a primary function of the respiratory system. It involves the exchange of oxygen and carbon dioxide between the air in the alveoli and the bloodstream.
-
Structural support: While the respiratory system does have structures that provide support (like the trachea and bronchial tree), this is not its primary function.
Final Answer
The function of the respiratory system is gas exchange.
