The human body. Part 2, An everyday miracle.

The second in a 7-part series in which Robert Winston looks in detail at the life of the human body in chronological order from birth to death. This part is about the start of life. Philipa and Geoff Watson are about to go through pregnancy and childbirth. Their story is featured from difficulties in conceiving to the birth of their baby. Imaging techniques are used to visualise in 3-D Philipa's internal anatomy and the female reproductive process. Male ejaculation is shown and the journey of sperm to the fallopian tubes is visualised. Laser microscopic footage shows in detail the sperm's meeting with an egg and the process of fertilisation. Embryonic and fetal development is shown in detail as is the development of the pregnant body; finally Philipa is shown giving birth.
