Human foetus at 16 weeks. Illustration of a human foetus developing in the uterus 16 weeks after fertilisation, around two-fifths of the way through pregnancy. The developing baby is an embryo from just after conception to around 8 weeks. It is then known as a foetus from around 8 weeks until birth, which occurs around week 39 to 41. At around 16 weeks, the foetus starts to move and its brain and other organs have mostly formed, though some organs are still very undeveloped. The placenta is at upper centre, connected to the foetus by the umbilical cord. | |
