Circulation & Breathing Together
Understand how the circulatory and respiratory systems work together: the lungs oxygenate the blood, the heart pumps it around the body, cells use the oxygen and produce carbon dioxide waste, and the blood carries the waste back to the lungs to be breathed out

Teaching Table
Set out your lesson
Explain how the heart and lungs connect oxygen delivery with carbon-dioxide removal.
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.
Use the supplied route cards and fictional counts only. No exercise or pulse measurement is required or inferred; personal health information stays private. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Understand how the circulatory and respiratory systems work together: the lungs oxygenate the blood, the heart pumps it around the body, cells use the oxygen and produce carbon dioxide waste, and the blood carries the waste back to the lungs to be breathed out
Own resting/post-exercise measurement clause blocked: fictional arithmetic is not a learner’s bodily observation. No personal exercise or medical recommendation.
- partial: Describe the cycle: lungs add oxygen to blood → heart pumps oxygenated blood to body → cells use oxygen → blood returns CO₂ to lungs
Own resting/post-exercise measurement clause blocked: fictional arithmetic is not a learner’s bodily observation. No personal exercise or medical recommendation.
- partial: Explain why heart rate and breathing rate increase during exercise (muscles need more oxygen)
Own resting/post-exercise measurement clause blocked: fictional arithmetic is not a learner’s bodily observation. No personal exercise or medical recommendation.
- blocked: Measure their own resting and post-exercise heart rate and explain the difference
No own-body measurement conducted or required; fictional counts are labelled and separate.
- partial: Can {{name}} explain why their heart beats faster when they run — and how their heart and lungs are working together to deliver more oxygen to their muscles?
Own resting/post-exercise measurement clause blocked: fictional arithmetic is not a learner’s bodily observation. No personal exercise or medical recommendation.
