AQA/EDEXCEL/OCR A Level Biology – Cardiac Cycle Graph Explained

This is my A Level Biology Cardiac Cycle revision resource, with a fully labelled graph showing pressure and volume changes, valve action and points A–E throughout the cardiac cycle.

I made this to make the cardiac cycle a little easier to visualise and revise, especially when learning how the different pressure changes link to the opening and closing of the valves.

Suitable for AQA, OCR and Edexcel, and includes an editable PowerPoint (.pptx) so you can use it for your own revision or teaching.

About me ♡
Hi! Welcome to therevisionlab ♡ I’m a Medical Biosciences student at Imperial College London, and I achieved A*, A*, A at A Level, AAA at AS Level, and mostly Grades 8–9 at GCSE.

Here you’ll find clear, organised GCSE, AS & A Level resources I created and used myself, all structured around the relevant exam board specifications. I hope they save you time, make studying easier and help you feel more confident in your exams!
