Female that forms gametes). Presenting as glands, the ovaries

Female Reproductive

            Ever thought to yourself, how come the female
reproductive system is so unique? The female reproductive system is unique
because it can reproduce, it can produce milk for a new born, and it can also
carry a small human being for nine months! We will soon discuss the females
breast, lower tors, fertilization and pregnancy, and birth and infancy.

Females Breast

            A females breast play a big role for new born babies.
When a baby is first born they depend on milk from the mothers breast. Internally,
each breast on female is formed mammary glands, a gland in mammals that
provides the milk to feed the young ones. As mentioned before, the females
breast form milk to feed infants. The milk is formed and put away by the
mammary glands and freed out the mammary vessel and nipple. Tips of sensitive
nerves in the nipple send signs to the brain to produce hormone oxytocin, which
is also utilized to assist mothers gather contractions in labor and control
bleeding, and start the let out of milk.  Next, in the breast area  is the areola a circular area of dark skin around
each nipple. The nipple itself can be found near the tip of each breast,
surrounding the nipple.

Lower Torso

is the lower torso, which is where the ovaries, ovarian ligament, uterus,
cervix of uterus, vulva, labia majora, labia minora, fallopian tube, and vagina
can be found. We’re going to start in the ovaries, the ovaries participates in
two roles in a woman’s’ reproductive arrangement, by reacting as glands and
gonads (organ that forms gametes). Presenting as glands, the ovaries form multiple
female sex hormones requiring estrogens and progesterone (two hormones that
maintain the health of a female). Estrogen supervises the formation of the
mammary glands and uterus during puberty and refreshes the process of the uterine
lining in the process of a female’s period (menstrual cycle). At birth ovaries
may have between several hundred thousand to several million circular bunches
of cells known as follicles, a little secretory sac. The uterus is almost the
same shape and size as a pear, but it sits in an upside down setting. The
uterus can be found on the midline rear of the urinary bladder and anterior of
the rectum. The figure of the uterus is an open and empty area where the egg
embeds itself and grows during pregnancy. The fallopian tubes enlarge sideways
from the corners of the fundus. The uterus builds a wide layer of vascular endometrial
tissue in development to collect a pollinated egg throughout the period of
ovulation. If the egg doesn’t become pollinated by the time it reaches the
uterus, it will move throughout the uterus and set off a females period, which
occurs almost every 28 days for most females. If it is a fortunate pollination
the egg turns into a baby, it arouses changes in the endometrium that guide to
the formation of the placenta.

            The vulva, also the common name for the outside female private
areas in the pubic region, including the labia, clitoris, and urethral and vaginal
openings. These organs perform together to help urination and sexual
reproduction. There are 2 labia’s one is the labia majora and the labia minora.
The labia minora is known to be the two hairless creases of skin that appear in
the vulva. Labia majora is a much lengthy and narrow arrangement expanding from
the pudendal cleft beyond the top of the labia majora. Within the labia minora
is the clitoris, the outer urethral orifice, and vaginal orifice. The clitoris
also extends to the internal tissues of the vulva.

            The labia majora is a pair of round creases of skin and is
a fragment of a females outer genitalia. The labia majora is there to guard the
inner, more fragile and delicate systems of the vulva. They can also be found in
the pubic area on the exterior of the body. Unlike the inner structure of the
vulva, the labia majora contain many pubic hairs that also assist to secure the
rest of the vulva from mechanical stress and abrasion. The adipose tissue of
the labia majora also helps shield the vulva from outside stress.

            The labia minora is a pair of cutaneous creases that
create a area of the vulva. They also perform as a protector of the clitoris,
urinary orifice , and vaginal orifice. They can be found in the vulva minor to
the mons pubis and medial to the labia majora in the pudendal split. Unlike the
surrounding, mons pubis and labia majora, the labia minora are sheltered with
hairless skin and contain very little adipose tissue. The labia minora has
several distinct layers of tissue. The outside layer is made of non-keratinized
stratified squamous epithelium continuous with surrounding skin. Next is a
layer of fibrous connective tissue never-ending with dermis of the skin.
Collagen and elastin protein fibers present in the connective tissues provide
strength and elasticity to the labia minora, while vascular and nervous tissues
support the cells of the outer epithelial covering.

             The fallopian tubes
are also known as the uterine tubes, which are a pair of four inch (ten
centimeters) long narrow tubes bringing the ovaries to the uterus. Egg cells
are taken to the uterus by the fallopian tubes behind ovulation. If sperm is
active following sexual intercourse, the ova may also be pollinated
while in the fallopian tubes. The outer most covering of the fallopian tubes, is
made of a serosa membrane of simple squamous epithelial tissue assisted by the
areolar connective tissue. They are far from submissive tubes in the female
reproductive system. In the process of fertilization they
play a big active role .

 The female vagina is an elastic, muscular tube
connecting the cervix of the uterus to the vulva and outside of the body. Posterior
to the urinary bladder and anterior to the rectum,
also located in the pelvic body cavity . Measuring around three inches in length
and less than an inch in width. But it can stretch to become several inches
longer and many inches wider during sexual intercourse and child birth. The
surface on the inside of the vagina is creased to give better elasticity and to
increase friction through intercourse. Secretions made by the vaginal
epithelium ease the vagina and have an acidic pH to stop the development of
bacteria and yeast. Acidic pH also makes the vagina an unwelcoming setting for
sperm, which has resulted in males making alkaline seminal fluid to neutralize
the acid and better the survival of the sperm. The tunica externa, the
outer most layer of the vagina is a heavy irregular connective tissue that
makes the outer protective cover of the vagina. The elastic build of the vagina
permit it to extend in both length and width.

Fertilization And

fertilization and pregnancy there is a fetus in the womb, which is also called
an embryo four weeks after it comes into existence. Around the time of
implantation, some cells in the blastocyst, the early phase of embryonic
development, organize themselves into a group that will give rise to the body
of the offspring. For about a week, its heart has been
beating . The head is defined, with eyes and rudiments of ears visible, and
inside there is the brain beginning, so far there are no bones. Where the arms
and legs will begin to grow, . bumps are starting to bulge. From the third
month on, all sorts of finishing touches will be put on. Fingernails will
appear, eyelids will form, facial features will gradually shift, lips form,
cheeks fill out, taste buds develop and sex organs begin to produce its first eggs.

            During the first trimester (eight weeks), the fetus goes
through a huge development process. The embryo develops from an egg fertilized
by sperm. It starts off as one cell, but then begins to break down into two
cells by the time it falls to the fallopian tube to the uterus. The embryo
becomes a pear shape. The head forms at the round end and the spine at the
pointed end. These two halves grow in the direction of each other until they
combine to create the neural tube. The embryo is now recognized as a mammal in
the forth week,. Buds of tissue from what will soon turn into the lungs,
pancreas, liver, and gallbladder, are found inside of the embryo getting ready
to form. A wide fold in the head then becomes visible to later develop the
brain. Ears appear, eyes form as stalks, and folds of tissue which will turn
into the jaws and other structures of the neck will begin to appear. Cartilage,
bone, and muscle of the rear appear in paired bulge.  The ears become visible, pits appear to mark
the nose, the upper and lower jaw start to form, and limb buds extend, in the
fifth week. Two folds of tissue meet and join in the front of the embryo to
make the front wall of the chest and abdomen.

            The fetus begins to take the shape of a baby during
the second trimester, . At the eighth week, the embryo is fully formed into a
tiny baby which is now a fetus. Body proportions begin to change as the limbs
and trunk grow, reducing the head from one-half to one-fourth of the body
length. The fetus is now able kick, curl its finger and toes, and squint its
eyes. Genitals from to determine the sex of the fetus. It also gains the
grasping reflex, which is familiar with new born babies. Through a stethoscope the
heartbeat is able to be heard.

            During the third trimester The fetus becomes capable of
life outside the womb during the third trimester . Fat begins
to build up, filling out a skinny body and preparing the baby for warmth in the
world outside the womb. During the last three months the
brain is developing rapidly .

            As you can see the female reproductive system is a very
big thing. The female body is capable of many things. But I think the most
interesting part is creating a baby and holding it for nine months. For all we
know the female reproductive system is way more then we know.
