What is the role of the respiratory system?

Delivers oxygen to and removes carbon dioxide from blood
Regulates body temperature through sweat
Circulates nutrients throughout the body
Produces hormones that regulate growth

The correct answer is: Delivers oxygen to and removes carbon dioxide from blood

The role of the respiratory system is fundamentally about gas exchange, which involves delivering oxygen to the blood and removing carbon dioxide from it. This process occurs primarily in the lungs, where oxygen from inhaled air passes into the bloodstream, enabling cells throughout the body to perform their metabolic functions. Carbon dioxide, a waste product produced by cells during metabolism, is transported back to the lungs and expelled when you exhale. This is crucial not only for maintaining the body's oxygen levels but also for maintaining the acid-base balance, which is vital for proper cellular function. Other options, while related to some body systems, do not accurately represent the primary function of the respiratory system. The regulation of body temperature, nutrient circulation, and hormone production are functions of different systems in the body—such as the integumentary, circulatory, and endocrine systems, respectively. Understanding the specific role of each bodily system is essential for proper first aid responses and overall health management.
