Lesson details
Key learning points
- Heart rate is the number of times the heart beats per minute (bpm).
- Stroke volume is the volume of blood pumped by the heart with each beat (measured in millilitres, mL).
- Cardiac Output is the volume of blood pumped by the heart per minute (measured in litres per minute, L/min).
- Cardiac output (Q) is calculated by multiplying the heart rate (HR) by the stroke volume (SV).
- A heart rate graph shows exercise intensity over a period of time.
Keywords
Heart rate - the number of times the heart beats per minute (bpm)
Stroke volume - the volume of blood pumped out of the heart by each ventricle with each beat (measured in millilitres, ml)
Cardiac output - the volume of blood pumped per minute by each ventricle of the heart (measured in litres per minute, l/min). Calculated as heart rate x stroke volume
Common misconception
Pupils often draw heart rate down to zero on a line graph.
Even at rest your heart is still beating, on average 72 beats per minute, to ensure blood is always circulating around the body to keep you alive.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
