Re: Jak dlouhá je pupeční šňůra, když Číňanka porodila do mísy tureckého záchodu a dítě se propadlo potrubím dolů?

The length of the umbilical cord varies from no cord (achordia) to 300 cm, with diameters up to 3 cm. Umbilical cords are helical in nature, with as many as 380 helices. An average umbilical cord is 55 cm long, with a diameter of 1-2 cm and 11 helices.[1] For unknown reasons, most cords coil to the left.[2] About 5% of cords are shorter than 35 cm, and another 5% are longer than 80 cm.[3]
