Solution
Fertilisation: Fertilization normally takes place in the female's Fallopian tube, which connects the uterus (womb) with the ovary. The uterus is made of muscle and it stretched to allow the baby's growth throughout the months of pregnancy. Every month one of the ovaries, in turn, releases an egg (ovum) which passes slowly along the tube towards the womb cavity.
Development: By 25 days from fertilisation, the body is developing. Head and trunk appear and tiny arm buds begin to form, followed by leg buds. Because the central nervous system (brain, spine and spinal cord) is so important, governing sensory and motor functions, the embryo's body is designed for rapid growth of head and back.
Birth: In the last weeks of pregnancy, the baby lies head downwards, as the head is normally the first part emerging at birth.
