Millions of Britons are clueless about their bodies, with two thirds literally being unable to tell their a**e from their elbow, a study found.
More than one thousand members of the Great British public wrongly identified the elbow bone as that of the coccyx, which is located just above the buttocks, or the coccygeal, which is the tail-like bone at the bottom of the spine.
Results also reveal 39 per cent do not know the difference between the kidneys and the liver, while a quarter cannot distinguish between the veins and arteries.
One in 10 men believe a woman’s period lasts for more than a month, while 56 per cent do not know why women have smear tests and a fifth are clueless as to the function of the ovaries.
In addition, some 24 per cent of adults do not know whether females have a prostate gland.
