It may be basic biology but the majority of British people cannot name the largest organ in the body, according to a survey.
A total of 75 per cent of people said they did not know it was the skin, while almost half (47 per cent) of people admitted to wrongly self-diagnosing an illness.
Perhaps in a sign of the times, findings also revealed more than half (58 per cent) of people prefer to check the internet about symptoms before consulting a doctor.
The survey of 2000 people, commissioned to coincide with the release of the eighth series of medical drama House on DVD, showed just under half of people believed their lungs were the largest organ in their bodies.
Demonstrating further confusion, 64 per cent and 43 per cent were unable able to correctly place their spleen and liver.
