Please note:The animal material used in this dissection has not been produced for the purpose of the video – it is a regular by-product of the meat industry, available for consumption from some butchers, or part of the waste stream if not used for dissection.

This video is for educational and demonstration purposes only. If you undertake your own dissection please take due safety precautions:
- Take care with sharp dissecting tools.
- Observe careful hygiene precautions after the dissection. Search @ava_hearts_biology on Instagram for more Biology
