The female reproductive system is responsible for the
nourishment
and
development
of the female gametes.
The
female reproductive system
is responsible for maintaining the necessary conditions for fertilization to occur.
The female
reproductive system
produces different hormones that are used for signaling.
The female reproductive system can be divided into
internal
and the
external
parts.
Internal parts:
Vagina
Cervix
Uterus
Fallopian tubes
Ovaries
External parts:
Labia
major
Labia
minor
Clitoris
The
vagina
is an elastic, muscular canal that connects the
external reproductive system
to the
cervix.
The
vagina
is naturally
moderately acidic
for protection.
At the
lower
portion of the uterus is the
cervix
, a muscle that holds the fetus during pregnancy.
The
cervix
expands once the baby is ready to be born.
The
cervix
contains
cervical mucus,
which facilitates the transport and nourishment of sperm to aid in fertilization.
Cervical mucus
- It can also be used as an indicator of a woman’s fertility.
The
uterus
is a
hollow muscular organ
that lies between the
urinary bladder
and the
rectum.
Uterus
has a very
soft lining
that holds the fertilized egg and nurtures it until it becomes a fetus.
The uterine wall has three distinct layers: the
perimetrium
, the
myometrium
, and the
endometrium.
The
endometrium
is the layer that is shed off during
menstruation.
The
fallopian tubes
connect the ovaries to the uterus.
Fallopian tubes
- Their primary function is to transport the egg cells to the uterus.
The
ovary
is the female gonad that contains the
egg
cells.
Ovaries
- It produces female sex hormones, estrogen, and progesterone.
The type of gametogenesis in female organisms is known as
oogenesis.
The human female reproductive system has functions like
egg cell
production,
fertilization
, and development of the
zygote
into a new organism.
Female gametes are known as
egg cells
or oocytes and are produced by the ovaries, the gonads of females.
Fertilization
is the process wherein the sperm cell penetrates the protective layers
of the egg cell in order to fuse their genetic materials and produce a
zygote.
