Which system contains the organs that help to process air?

• A. Reproductive
• B. Endocrine
• C. Respiratory
• D. Integumentary

Answer: (C)

The respiratory system is the one that contains the organs that help to process air. It includes structures like the nose and mouth for intake, the throat and windpipe, and the lungs with their branching airways. Its job is to bring air into the body, filter out particles, warm and humidify it, and then exchange gases. In the lungs, oxygen from the inhaled air passes into the blood, while carbon dioxide moves from the blood into the air to be exhaled. This gas exchange happens mainly in the tiny air sacs called alveoli and is coordinated with the circulatory system to deliver oxygen to tissues and remove CO2. Other systems don’t process air for gas exchange. The reproductive system focuses on producing offspring, the endocrine system on hormone production and regulation, and the integumentary system (skin and related structures) protects the body and helps regulate temperature but does not handle air processing or gas exchange.
