Blood circuit — Heart Valley · Body Quest

The heart has two sides with different jobs. Sort the facts. Laid end to end, your blood vessels would wrap around the Earth more than twice.

Your task

Sort each statement.

Arteries carry blood away from the heart; veins bring it back.
A fictional journey, not medical advice. If you feel unwell, talk to a trusted adult or a health professional (Portugal: SNS 24 — 808 24 24 24; emergency: 112).
Every body is different and every body is valid. Nothing about you or your health is collected.

Real science

Laid end to end, your blood vessels would wrap around the Earth more than twice.

Heart Valley

A fictional journey, not medical advice — we never diagnose. Pain, injuries or worries: talk to a trusted adult (SNS 24: 808 24 24 24; emergency 112; SOS Criança 116 111). Nothing about you or your health is collected; progress stays on this device.
