The respiratory system helps us breathe by bringing in oxygen and removing carbon dioxide, like how fresh air fills a balloon, and we release used air.
Important parts include the lungs (like two sponges), the trachea (a tube), and the diaphragm (a muscle).
It's like a see-saw. When you inhale (up), your diaphragm contracts, and your chest expands; when you exhale (down), your diaphragm relaxes.
Inside your lungs, picture thousands of tiny balloons (alveoli) where oxygen meets blood and carbon dioxide gets carried away.
Think of your diaphragm as a superhero muscle. It flattens when you breathe in, making space for your lungs to expand.
Sometimes, like a clogged straw, your airways can get blocked, causing issues such as asthma or bronchitis.
