a model will help you review the fundamentals
the female sex organs
as seen from outside consists of several fold of
skin or tissue called the *** or lips
this *** cover the urethra
through which urine is pass and the entrance to the ***
cutting through this model
this organs can be seen as they actually appear in vertical section
through the midline
here is the *** the *** had a moist lining
called the mucous membrane it wall line fold
which can be easily stretch a membrane partly covered the entrance to the
***
this is the *** or Maid in head
its absence does not mean like a virginity
sent it may be accidentally broken during childhood
the uterus shown here in a front view
is a small pear-shaped organ
normally only about half the size of a fest below it is the ***
and connected to it at the top
are two tubes the fallopian tubes and two
ovaries
in a section through these organs we can see the ***
this is the narrow neck of the uterus and extend into the ***
the wall of the uterus are very thick
but may be stretched so that the uterus can enlarge too many times its original size
during pregnancy one end of the fallopian tubes
is open so that eggs or ova
from the adjacent ovaries may easily enter
and be carried to the uterus
the ovary is a gland in which eggs are constantly being formed
each am in shape ovary a is about an inch and a half in length beside producing eggs
these glands secrete fluid into the blood
which are responsible for the development of female characteristics
and other parts of the body
such as breast pair and skin
but from puberty on the primary function of the ovaries
is the production of eegs a in a closer view
we can watch the development of un egg remember that while this one is growing
all the other is a growing also but usually only one
egg reaches maturity every 28 days
after reaching full development it breaks through the ovarian wall
and passes into the fallopian tube
this breaking through with the
egg is called relations the fully developed
egg is only one to 270 inch in diameter
when mature
each egg is capable if fertilized of developing into a baby
moreover each egg carries all of the hereditary characteristics
of the mother since the function of the uterus
it primarily that a receiving the fertilized egg
and nourishing the developing child the wall
undergo a regular cycle in preparation for this job
the lining of the uterus become soft and spongy
an engorged with blood and fluids this progresses during the final stages of
the development of the egg
extrusion from the ovary and its passage through the tube
if fertilization of the egg does not occur
the uterine wall lining breaks down and it discharged from the body
as the menstrual flow if we call this
unset of *** the first day of the menstrual cycle
we can watch the various elements as they record during
each 28-day period after the menstrual flow stops
about the fourth day the uterine lining begins to build up again
meanwhile eggs are being formed in the ovaries in the normal cycle
all of the elation that carries about the14th day and an egg is extruded
into the fallopian tube it started slow passage toward the uterus
but it's not fertilized it dissolves away or disappeared in the tube
after the 28th day
*** occur again and the cycle is repeated
this then is the structure and function of the female reproductive organs
the ovaries which every 28 days
discharge mature eggs into the fallopian tubes the uterus
with during the same period get ready to receive the egg
in case it is fertilized by contact with the male ***
if fertilization of the egg does not occur
the egg itself dissolved or disappears and the uterine wall linings
now deprived of their special function to nourish the developing child
breakdown and are discharged the menstrual flow
overall the average menstrual cycle
usually occurs every 28 days in many cases it may be somewhat longer
or shorter because it depends on the proper functioning of many glands
its normal time schedule maybe easily upset by nervous strain
emotion or illness the process is regularly repeated however
every 28 days unless fertilization of the egg occurs
and pregnancy begins these are the fact of the female reproductive system
this is the information with you dad should
clearly understand before you can pass on correct knowledge to your child when he is old enough to understand
