Biology KS3 & KS4: How humans heal themselves
A look at how the body heals itself.
Combining CGI scenes with real life action in the boxing ring, it follows the progress of a boxer's black eye.
Featuring ruptured blood cells, platelets and fibrin it covers all of the essential elements of clotting.
The wider immune system, and the role of macrophages in the bruise colour change is described.
This clip is from the series Inside the Human Body.
After viewing, students could investigate why not all body tissues are able to repair themselves like this, and thus the importance of stem cell research to enable body parts to heal themselves.
Their investigation could include a look into the ethical debate surrounding stem cell research, and case studies of how stem cell research has already helped patients.
This clip will be relevant for teaching Biology at KS3 and KS4/GCSE in England, Wales and Northern Ireland and National 4/5 in Scotland. Appears in AQA, OCR, EDEXCEL, CCEA, WJEC, SQA
