The respiratory system helps our bodies get the oxygen we need by using the lungs to inhale air. When we breathe in, oxygen enters the lungs and moves into tiny air sacs called alveoli. From there, oxygen passes into the blood and is carried to all our cells. At the same time, carbon dioxide, a waste gas, is removed from the blood and exhaled. If the respiratory system doesn’t work properly, we might not get enough oxygen, leading to symptoms like shortness of breath, fatigue, or even serious health problems. Keeping this system healthy is essential for our overall well-being.
How does the respiratory system ensure that our bodies get the oxygen we need, and what can happen if this system doesn’t function properly?
