Let's see the different parts of the female
reproductive system.
Ovaries
There are a pair of ovaries in the female reproductive system that contain the
pre matured egg cells.
Oviducts
There are two oviducts which unite into an
elastic bag like structure known as uterus.
Uterus
it is called the womb where
the implantation and development of baby takes place.
Cervix
the uterus opens into
the vagina through the cervix.
Vagina
it is the passage where sperms are
deposited by the penis of male reproductive system during sexual intercourse.
Now let's see the production of female gametes.
When do girls start producing egg cells ?
when a girl is born, the ovaries already contain thousands of immature eggs
By reaching puberty the eggs start maturing.
One egg is produced
every month by one of the ovaries the
egg released by the ovary is collected
in the fallopian tubule. It is the place where the fertilization takes
place by the fusion of sperm and egg
cells then how do the sperms reach
fallopian tubule. the sperms get
deposited in the vagina of the female
reproductive system by the penis of the
male reproductive system during sexual
intercourse. The sperms travel towards
fallopian tubule and finally
reaches the egg cell and fertilizes it.
The hormones secreted by the ovaries
prepares the uterus to receive and nurture
the growing embryo the walls of the
uterus becomes thick and richly supplied
with blood to nourish the growing embryo
the fertilized egg, the zygote gets
implanted in the lining of the uterus
and starts dividing.
Placenta is a special tissue that helps the embryo to
get nutrition from the mother's blood it
is embedded in the uterine wall and
provides glucose and oxygen to the
embryo. Placenta are also transferred the
waste generated by the embryo into the
mother's blood.
The development of the
child inside the mother's body takes
approximately nine months.
This period is called as gestation period.
The child is born as a result of rhythmic contractions
of the muscles in the uterus.
