The human body is like a super cool machine with different systems that help us live and play. One of these important systems is the respiratory system, which is all about breathing!
Every time you take a breath, your body is doing something amazing. You breathe in through your nose or mouth, and that’s how you get oxygen, which is a gas that your body needs to stay alive. This oxygen travels down a path that includes the pharynx, larynx, and trachea until it reaches your lungs.
Inside your lungs, oxygen is swapped for another gas called carbon dioxide. This is a bit like trading a toy with a friend! Oxygen goes into your red blood cells, which are like tiny delivery trucks that take oxygen all over your body. Meanwhile, carbon dioxide, which your body doesn’t need, is sent back out when you breathe out.
Breathing out, or exhaling, is how we get rid of carbon dioxide. It’s a waste product, kind of like taking out the trash. You breathe it out through your nose or mouth without even thinking about it!
Learning about the respiratory system shows us just how incredible our bodies are. If you enjoyed discovering how we breathe, there are many more exciting things to learn about the human body. Keep exploring and have fun!
Balloon Breathing Experiment: Try this fun activity to see how your lungs work! Take a balloon and blow it up. Notice how the balloon expands as you blow air into it. This is similar to how your lungs fill with air when you breathe in. Now, let the air out of the balloon slowly. This is like exhaling, when your lungs release carbon dioxide. Can you think of other objects that expand and contract like your lungs?
Breathing Buddy: Find a small stuffed animal or toy and lie down on your back. Place the toy on your belly and watch it rise and fall as you breathe in and out. This helps you see how your diaphragm, a muscle under your lungs, moves when you breathe. Try taking deep breaths and notice how the toy moves differently compared to when you take shallow breaths. Why do you think deep breathing is important?
Nature Walk Observation: Go for a walk outside and observe the plants and trees around you. Remember that plants take in carbon dioxide and release oxygen, which helps us breathe. Can you find different types of plants? Think about how important they are for our respiratory system. How do you feel when you take deep breaths of fresh air outside compared to inside?

**Systems of the Human Body: The Respiratory System**
The respiratory system is responsible for breathing. Through the nose or mouth, we obtain oxygen, which passes through the pharynx, larynx, and trachea to the lungs. In the lungs, oxygen is exchanged for carbon dioxide. The red blood cells carry oxygen to all parts of the body. Carbon dioxide is a waste product that we need to eliminate from our body by exhaling through the nose or mouth. This process occurs without us even realizing it.
