WOMEN

8. FECUNDATION
• If there is any ovum (egg cell) released, the
egg cell and the sperm cells meet.
9. FECUNDATION
• Once a sperm fertilizes an OVUM, it becomes
a zygote. The zygote then divides itself to
form a very tiny ball called an embryo. The
embryo continues downwards and finds itself
a confortable place in the uterus.
10. FOETAL DEVELOPMENT
• The embryo becomes a foetus (say fee-tus) eight weeks after
fecundation. The foetus depends upon its mother for
protection, oxygen and nutrients as it develops.
Inside the uterus, there is a bag called the. ‘Amnion’
11. BIRTH
• After nine months the baby is fully developed
and ready to be born into the big wide world.
12. The Menstrual Cycle
• The menstrual cycle typically lasts 28 days;
approximately 1 month.
– One cycle is the amount of time from the
beginning of one period to the beginning of the
next period.
• The beginning of a period is marked by the
release of the blood and lining from the inside
of the uterus.
– This flow of blood typically lasts 3-7 days and is
called menstruation.
