This GCSE worksheet focuses on the heart rate and the cardiac cycle.

It contains questions that ask students to identify the natural pacemaker of the heart, pinpoint where it’s located, understand the sequence of chamber contractions during a heartbeat, and recognise the main blood vessels involved in the circulation

Also, the worksheet addresses the use of artificial pacemakers and why they are battery-operated, as well as why the resting heart rhythm is controlled by the unconscious nervous system.
