Corrected sentence (grammar): A blood clot is a sticky lump that can stop blood flow. That's dangerous!
Child-friendly version: A blood clot is a sticky lump that can block blood from moving. That can be dangerous.
Quick grammar notes:
- Do not use all caps (A BLOOD CLOT); write normally as "A blood clot."
- Either "stop blood flow" or "stop the flow of blood" is correct; shorter is fine for a child.
- "That’s" is a correct contraction of "That is."
Simple, step-by-step explanation for a 5-year-old:
- Blood moves around your body like water in a hose to keep you healthy.
- Sometimes a sticky lump (a blood clot) can form and stop the blood from moving.
- If blood can't move, parts of the body can get hurt. That is why a clot can be dangerous.
What to do: If you or someone feels very sick, tell a grown-up right away. Doctors can help make it better.
