Artwork illustrating a side view of a human foetus at 8 weeks (2 months) gestation. The foetus is surrounded by the amnion, a protective fluid- filled sac. The placenta (orange, lower centre) is connected by the umbilical cord (white loop, centre) to the foetus, and provides oxygen and nutrition. The end of the eighth week marks the point at which an embryo becomes known as a foetus.
