We had a visit from a student from Leeds University today. He was studying Biomedical Sciences and taught us all sorts about what keeps us alive and what keeps us healthy.
We took on the role of aliens (hence our headgear) and pretended we were studying this strange species from another planet: humans.
We investigated how much we breathe every minute and learnt about what breathing actually is and why we need to do it.
Our diaphragm moves up and down as we breathe in and out and Mr Cook gave us these mini models so that we could see what was happening inside us.
We created our own body system with half of us being oxygenated blood travelling to our organs and the other half carrying the deoxygenated blood back to the heart and the lungs. The deoxygenated team were much more efficient that the oxygenated team – particularly Dan and Matthew.
