Original sentence: CAPILARIES are the thinnest blood vessels. They connect the arteries and the veins
Corrected sentence: Capillaries are the thinnest blood vessels. They connect arteries and veins.
Step-by-step fixes:
- Spelling: "CAPILARIES" should be spelled Capillaries (with two "r"s).
- Capitalization: Use a capital letter only at the start of the sentence: Capillaries, not all caps.
- Punctuation: Add a period at the end of the second sentence.
- Articles: You can say "connect arteries and veins" instead of "connect the arteries and the veins" — both are correct, but the shorter phrase is simpler.
What that means (for a 6-year-old): Capillaries are tiny, tiny blood tubes that join the big tubes (arteries) to the tubes that bring blood back (veins). They help blood give food and oxygen to your body’s cells.
