Verified step by step guidance

Identify the main components of the respiratory system, which include the lungs, trachea, bronchi, and alveoli.

Understand the process of gas exchange, which occurs in the alveoli where oxygen from the air is exchanged with carbon dioxide from the blood.

Recognize that the primary function of the respiratory system is to facilitate this gas exchange, providing oxygen to the blood and removing carbon dioxide.

Differentiate this function from other bodily functions such as nutrient transport, temperature regulation, and blood cell production, which are primarily roles of other systems like the circulatory, integumentary, and skeletal systems respectively.

Conclude that the primary function of the respiratory system is to exchange gases between the atmosphere and the blood, as it directly involves the respiratory structures and processes.
