Can you explain how the respiratory system functions, including the roles of the nose, windpipe, lungs, and air sacs?
Understand the Problem
The question appears to be related to the respiratory system, explaining how air is filtered and oxygen is utilized in the body while producing carbon dioxide. It involves understanding biological concepts related to respiration.
Answer
The respiratory system filters and warms air through the nose, directs it down the windpipe to the lungs, where air sacs exchange gases, allowing oxygen into the bloodstream and removing carbon dioxide.

Answer for screen readers
The respiratory system filters and warms the air through the nose, then directs it down the windpipe to the lungs where air sacs facilitate gas exchange, allowing oxygen into the bloodstream and removing carbon dioxide.
More Information
The respiratory system's primary job is to bring in oxygen for the body's use and to remove carbon dioxide, a waste product of metabolism. Nose hairs and mucus protect against dust and germs, and the windpipe divides air into the lungs, which consist of air sacs where the crucial exchange of gases occurs.
Tips
A common mistake is to forget the roles of each part in the system. Remember that the nose filters and humidifies air, the windpipe transfers air to the lungs, and the air sacs are where gas exchange happens.
