Human Respiratory System Grade 5 Science Worksheet

We all breathe, but how? Let's uncover the secrets of our respiratory system, the superhero behind each breath!

The nose is like a filter. It warms and cleans the air we breathe, making sure it's perfect for our lungs.

Air travels down the windpipe to our lungs. It's like a journey! Lungs help us take in oxygen.
