The video shows close up images of bacteria and macrophages, as well as sebum secretion.
This short film is from the 大象传媒 series, Inside the Human Body.
Teacher Notes
Your class could try and create a model of skin using different materials.
How can they keep water in and invaders out? What properties would their materials need to have?
They could also investigate the part skin plays in homeostasis, concentrating on the regulation of temperature and water.
Skin could be studied as a sensory organ and practical investigation could be carried out into the density of touch receptors in different parts of the body.
This short film 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
