A Level Biology OCR - Animal Transport - Heart structure, cycle and initiation of Cardiac cycle

This resource has everything needed to teach and learn about the heart at OCR A level.
The booklet starts at the basic structure of the heart and the main structures of heart anatomy both internal and external.
The Structure is explained using a simple gap fill activity to allow students to learn and complete the first page of the booklet.
The next is labeling the external and internal structures to allow students to orientate themselves.
The next part of the booklet explains the key stages in the cardiac cycle using a simple gap fill and then goes on to explain the cardiac cycle graph with clear labels of what is happening the pressure changes in the atria and ventricles.
The next part of the booklet explains the initiation of the cardiac cycle how the cardiac cells are myogenic and how the natural pacemaker SAN node triggers a wave of excitation over the atria and how the AVN node triggers ventricular contraction.
The last part of the booklet explains ECG graphs and what each part does and how to recognise abnormal ECG traces.
