1. Stroke volume is 60cm3, heart rate is 60bpm calculate the cardiac output in cm3

2. Cardiac output is 5 dm3, heart rate is 54 bpm, calculate stroke volume in cm3

3. 1 heart beat takes 0.8 seconds. Cardiac output is 3600 cm3 per minute. Use the information to work out the stroke volume in cm3

• Atrioventricular node

• Sinoatrial node

• Bundle of his

• Purkinji fibres

Open Ended
