Question

What is the function of the respiratory system?

Answer 1

Answer is A because your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood.

Answer 2

The lungs and respiratory system permit us to relax. They bring oxygen into our bodies (called inspiration, or inhaling) and send carbon dioxide out (called expiration, or exhalation). This trade of oxygen and carbon dioxide is called respiration.
