Have you ever wondered how your body gets the oxygen it needs to keep you alive and full of energy? Let’s take a fun journey through the respiratory system to find out!
Every time you take a breath, air enters your body through your nose. Inside your nose, there are tiny hairs that work hard to clean the air by trapping dirt and germs. They also make the air warm and moist, which is just what your lungs like!
After the air is cleaned, it travels down a path that includes the pharynx and larynx. Then, it moves into a tube called the trachea, or windpipe. The trachea splits into two tubes called bronchi, which lead into each lung. Inside the lungs, the bronchi branch out into even smaller tubes called bronchioles.
Your lungs are like amazing oxygen factories! They take the oxygen from the air and send it into your blood. This oxygen travels all over your body, helping your organs and cells work properly. The lungs also get rid of carbon dioxide, a waste gas that your body doesn’t need.
Inside your lungs are tiny air sacs called alveoli. These sacs are super important because they absorb oxygen and pass it into your blood. They also help remove carbon dioxide from your blood so you can breathe it out.
Underneath your lungs is a muscle called the diaphragm. It helps you breathe by moving up and down. When you breathe in, the diaphragm moves down to let your lungs fill with air. When you breathe out, it moves up to push the air out. Try placing your hand on your belly and take a deep breath—you can feel your diaphragm at work!
To keep your respiratory system healthy, it’s important to breathe clean air and avoid things like smoking and pollution. Exercise is also great for your lungs because it helps them stay strong and efficient.
Now you know all about the amazing journey of air through your respiratory system. Remember to take deep breaths and enjoy the fresh air!
Breathing Buddy Experiment: Create a simple model of the lungs using a plastic bottle, balloons, and straws. Cut the bottom off a plastic bottle and attach a balloon to the end of a straw. Insert the straw into the bottle’s neck and seal it with clay or playdough. Cover the open bottom with a larger balloon to act as the diaphragm. When you pull the balloon at the bottom, watch how the balloon inside inflates, just like your lungs when you breathe in. Discuss with your friends or family how this model represents the respiratory system.
Oxygen Adventure Game: Imagine you are a molecule of oxygen traveling through the respiratory system. Draw a map showing your journey from the nose to the alveoli. Label each part of the system you pass through and write a short story about your adventure. What do you see and feel along the way? Share your story with your class or family.
Breathing Observation Challenge: Spend a day observing how different activities affect your breathing. Notice how your breathing changes when you are sitting, walking, or running. Try to count how many breaths you take in one minute during each activity. Discuss with a friend or family member why you think your breathing rate changes and how it helps your body get the oxygen it needs.

The respiratory system extracts oxygen from the air, which our cells need to live and grow. It also eliminates carbon dioxide that cells produce after using oxygen. This process is known as respiration, which is an automatic and involuntary process.
Air enters through the nose, where it encounters tiny hairs that moisten, heat, and clean it to keep dirt out of the lungs. The air continues down the pharynx, larynx, and then the trachea. The trachea, or windpipe, splits into two to form the bronchi inside the lungs. Once the air is inside the lungs, it travels through pathways called bronchioles.
The lungs are the most important organs in respiration. They take in oxygen from the air and expel the carbon dioxide that the body doesn’t need. The alveolar sacs absorb that oxygen and send it to the blood for distribution throughout all the organs and cells of the body.
The diaphragm, located under the lungs, helps fill the lungs with air during inhalation and expels the air during exhalation. The air we exhale contains carbon dioxide and waste, and it is warm; you can feel the heat if you place your hand over your mouth while breathing out.
Smoking and pollution can harm the respiratory system. Exercise and breathing clean air are essential for maintaining good respiratory health.
