17 Menstruation Also called a 'period'. The loss of blood and tissue from the lining of the uterus
through the vagina during the menstrual cycle.

18 Embryo An organism in the early stages of development. 1 2 3 4

19 Fetus ( Foetus) An unborn baby. Usually eight weeks after conception

20 Amniotic fluid Liquid that protects the fetus in the uterus.

21 Placenta The organ in the uterus of pregnant mammals that allows the transfer of nutrients
and waste products between the mother and the fetus through the umbilical
cord.

22 Ovulation The process of releasing an egg from an ovary.

24 Umbilical The cord that connects the fetus (foetus) to the placenta. It contains blood
cord vessels.

25 Placenta The organ in the uterus of pregnant mammals that allows the transfer of nutrients 5. Menstrual cycle process
and waste products between the mother and the fetus through the umbilical
cord. 1 The start of the cycle, day 1, is when bleeding from the vagina begins. This is
caused by the loss of the lining of the uterus, with a little blood. This is called
5. Pregnancy menstruation or having a period.

2 By the end of about day 5, the loss of blood stops. The lining of the uterus begins
to re-grow and an egg cell starts to mature in one of the ovaries.

3 At about day 14, the mature egg cell is released from the ovary. This is called
ovulation. The egg cell travels through the oviduct towards the uterus.

4 If the egg cell does not meet with a sperm cell in the oviduct, the lining of the
uterus begins to break down and the cycle repeats
