A practical exploration of how the cardio-respiratory systems work together
Lesson details
Learning outcome
I can explain how my cardiovascular and respiratory systems work together to support performance in sport.
Key learning points
- Gaseous exchange is when oxygen and carbon dioxide move or diffuse from high concentration to lower concentration.
- Oxygen is delivered to the circulatory system and then to the working muscles.
- The respiratory system gets oxygen into the body, then the circulatory system transports it to the body.
Keywords
Cardio-respiratory - the combined functions of the cardiovascular system or heart and blood vessels and the respiratory system or lungs and airways
Gaseous exchange - the process where oxygen and carbon dioxide are transferred between the alveoli in the lungs and the bloodstream via capillaries
Performance - the execution of an action or the ability to achieve a task effectively and efficiently
Common misconception
All of the oxygen we breathe in is used by the muscles.
The body only extracts a small percentage of the oxygen in each breath so it is important we keep breathing during and after exercise. You can only moves gases to an area of lower concentration so once that is equal diffusion stops.
Teacher tip
This lesson is a nice (optional) practical exploration of the combined pathway of oxygen from the atmosphere right through to the working muscles and then carbon dioxide back out of the body. You might find it is worth saving it as a revision lesson in Year 11 and to give minimal explanation.
Equipment
mini whiteboards to capture and arrange the name/ function of different parts of the respiratory tract and circulatory system responsible for getting oxygen to the muscles and carbon dioxide out

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.
