Let's take a fun journey to understand how oxygen and carbon dioxide travel through our bodies. Breathing In: Oxygen Enters When you take a big breath, the air around you rushes into your nose or mouth. This air is full of something vital called oxygen. Oxygen is our fuel in the air because our bodies need it to stay alive. Down to the Lungs Once the oxygen enters your nose or mouth, it travels down the trachea tube. The trachea leads directly to both of your lungs. Your lungs contain millions of tiny air sacs called alveoli responsible for gas exchange. Meeting the Blood These alveoli are like little balloons that fill up with oxygen when you breathe in. Surrounding these alveoli are lots of small blood vessels called capillaries. The oxygen jumps from the alveoli into the capillaries, hits a ride with your blood, and hugs your hemoglobin explicitly. Oxygen's Big Journey The oxygen is in your blood, ready to travel around your body. It uses the blood as a super-fast train to get to every part of you—your brain, muscles, and even your toes! The oxygen helps all these parts to work correctly and keep you feeling at your best. Breathing Out: Carbon Dioxide Exits While oxygen does life-saving work, it also helps create energy in your body. But, just like any job, this process makes some waste. This waste is called carbon dioxide, and it needs to leave your body so you can stay healthy. Back to the Lungs The carbon dioxide gets picked up by your blood and travels back to your lungs. Remember those tiny alveoli balloons? This time, they fill up with carbon dioxide instead of oxygen.
