Demonstrating Biology: It Takes Guts

Produced by Teachers TV, this video illustrates how looking at a pig's entrails can be used to investigate the digestive system.

Nigel, biology teacher at King Charles I school, explains that once he receives the entrails from the abattoir, hygienic handling and storage is of paramount importance. Before any demonstration Nigel is aware of the sensitivities and religious issues around exposing animal organs and reassures his students that the animal was not killed for demonstration purposes.

Once everything is prepared he shows the digestive system in detail from one end to the other. He enlists the help of some volunteers and also enhances his lesson by using endoscopy images obtained from the Royal Free Hospital in London.

It is with great regret that Dr Nigel Collins, the presenter of this programme, passed away after the programme was completed. Teachers TV continued to broadcast the programme with the kind permission of his family.
