The female reproductive system:
In the process of human reproduction, and involved 2 types of sex cells or gametes. The gametes, or sperm, and female gametes, the egg or the egg, and the fulfillment of the female reproductive system to create a new individual.
Systems of both males and females is necessary for reproductive cloning. Female in need to mention it to fertilize an egg, although it is bearing the offspring during pregnancy and childbirth.
Humans, like other organisms, pass certain characteristics of themselves for the next generation through their genes, and private transport companies of the qualities of humanity. Genes with parents to their children are what make children similar to others in their families, but they are also what make each child unique. These genes come from the sperm of a male and a female egg, produced by the reproductive systems of males and females.
About the female reproductive system:
Most of the species and two sexes: males and females. Each sex has its own unique reproductive system of its kind. They differ in shape and structure, but are designed specifically for the production of both, feed, and transport either the egg or sperm.
In contrast to the male and female human reproductive tract has completely located in the pelvis. Called the outer part of the female reproductive system vulva, which means cover. Located between the legs, and vulva covers the opening of the vagina and other genital existing within the body.
And called on the fleshy area located just above the top of the vagina and pubic mons. He called for two pairs of skin flaps of the labia (which means lips) surround the vaginal opening. The clitoris is located, a small sensory device, towards the front of the vulva where the folds of the labia registry. Between the lips and the openings of the urethra (the canal that carries urine from the bladder to outside the body) and vagina. Once girls become sexually mature, and cover the outer labia and pubic hair from the mons pubis.
And female reproductive organs are internal vagina, uterus and fallopian tubes and ovaries.
The vagina is a muscle, and a hollow tube extending from the vaginal opening to the uterus. Vagina about 3 to 5 inches (8 to 12 cm) long in a woman grown. Because they are walls of muscle, it can expand and contract. This ability to become wider or narrower allows the vagina to accommodate something sound of the beast on a large scale like a baby. And lined the walls of the vagina and the muscles with mucous membranes, which keep it protected and moist.
Vagina serves three purposes:
1. Where it is inserted into the penis during sexual intercourse.
2. He called in a way that takes the child of a woman’s body during childbirth, the birth canal.
3. It provides the way blood menstruation (period) to leave the body of the uterus.
Called a thin sheet of tissue one or more of the holes where the hymen partially covers the vaginal opening. Hymen is often different from female to female. Most of the women had been extended search for a hymen, or torn after their first sexual experience, the hymen may bleed a little (this usually causes little, if any, pain). Some women who have had sex, you do not have a lot of change in their virginity, though.
Vagina connects with the uterus, or womb, the cervix (which means neck). Cervical and strong, thick walls. Opening of the cervix is ??too small (no wider than the straw), and for this reason can never be lost beast within the body of the girl. During childbirth, the cervix can expand to allow the child to pass through.
Is the shape of the uterus, such as pear upside down, with thick lining and muscular walls – in fact, the uterus contains some of the strongest muscles in the female body. These muscles are able to expand and contract to accommodate the growing fetus and then help push the baby through labor. When a woman is not pregnant, the uterus is only about 3 inches (7.5 cm) long and 2 inches (5 cm) wide.
In the upper corners of the uterus, fallopian tubes connect the uterus to the ovary. Ovaries and two oval-shaped, which is located on the top left and right of the uterus. They produce, store, and release eggs in the fallopian tube in a process called ovulation. Each ovary measures about 1 ½ to 2 inches (4-5 cm) in a woman grown.
There are two fallopian tubes, attached to each side of the uterus. Fallopian tube about 4 inches (10 cm) long and wide around like a piece of spaghetti. Within each tube is a small alley no wider than a needle sewing. At the other end of each fallopian tube is an area fringed like repression. This fringed area wraps around the ovary but not attach it completely. When an egg pops from the ovary, it enters the fallopian tube. Once the egg in the fallopian tube, a small hair in the lining of the tube to help pay down a narrow corridor toward the uterus.
The ovaries are also part of the endocrine system because they produce female sex hormones such as estrogen and progesterone.
What woman’s reproductive system: Can
And the reproductive system of women that women can:
• Production of eggs (eggs)
• sexual intercourse
• protect and nourish the fertilized egg until it is fully developed
• give birth
That sexual reproduction can not happen without the sexual organs called the gonads. Although most people think of the gonads also said the testicles, both sexes actually gonads: In females the gonads and ovaries. Female gonads produce female gametes (eggs), and the gonads produce gametes MALE Male (sperm). After the fertilized egg of sperm, fertilized egg is called the zygote.
When the baby was born, her ovaries contain hundreds of thousands of eggs, which are still active until puberty begins. At the age of puberty, the pituitary gland, located in the central part of the brain, starts making hormones that stimulate the ovaries to produce female sex hormones, including estrogen. Secretion of these hormones lead to the girl to develop into sexually mature woman.
Towards the end of puberty, girls begin to release eggs as part of the menstrual cycle called the menstrual cycle. Approximately once a month, during ovulation, an ovary sends a tiny egg into one of the fallopian tubes.
However, if the egg is fertilized by a sperm while in the fallopian tube, and dry eggs and leaves the body about 2 weeks later through the uterus – this is menstruation. Blood and tissues of the inner lining of the uterus combine to form the menstrual flow, which in most of the girls runs from 3 to 5 days. And called the girl’s first menstrual period.
It is common for women and girls to experience some discomfort in the days preceding periods. Premenstrual syndrome (PMS) includes both physical symptoms and emotional that many girls and women get right before periods, such as acne, bloating, fatigue, back pain, sore breasts, headaches, constipation, diarrhea, and, food cravings, depression and irritability , or difficulty concentrating or handling stress. PMS is usually at its worst during the 7 days before her period starts and disappears once it begins.
Many girls also experience abdominal cramps during the first few days of periods caused by prostaglandins, chemicals in the body that make smooth muscle in the contract the uterus. Such involuntary contractions either dull or sharp and intense.
It can take up to 2 years of onset of menstruation to the girl’s body to develop a regular menstrual cycle. During that time, her body is adjusting to the hormones puberty brings. On average, the menstrual cycle for an adult woman is 28 days, but the range of 23 to 35 days.
If the female and male have sex within several days of ovulation and female, and fertilization can occur. When he stated ejaculates (when semen leaves a male penis), and between 0.05 and 0.2 fluid ounces (1,5 up to 6.0 ml) of semen was deposited in the vagina. Between 75 and 900 million sperm in this small amount of semen, and they “swim” up through the vagina and cervix and uterus to meet the egg in the fallopian tube. It only takes one sperm to fertilize an egg.
About a week after the sperm fertilizes the egg, fertilized egg (zygote) has become multi-cell blastocyst. Blastocyst is about the size of a pinhead, and it’s a hollow ball of cells with fluid inside. The blastocyst burrows itself in the lining of the uterus, called the endometrium. Hormone estrogen causes the lining of the uterus to become thick and rich with the blood.
Progesterone, another hormone released by the ovaries, keeps the endometrium thick with blood so that the blastocyst can attach to the uterus and absorb nutrients from it. This is called a transplant.
The cells from a blastocyst into food, and the last stage of development, the embryonic stage, begins. The inner cell forming flattened circular shape called the embryonic disk, which will develop into a child. Outer cells become thin membranes that form around the child. Cells multiply thousands of times and move to new positions to eventually become the embryo.
After about 8 weeks, the fetus is about the size of the adult thumb, but almost all of its parts – set up – the brain and nerves, heart, blood, stomach, intestine, muscle and skin.
During the embryonic stage, which lasts from 9 weeks after fertilization to birth, development continues as cells multiply, move, and change. Fetus floats in amniotic fluid inside the amniotic sac. Fetus receives oxygen and nutrition from the mother’s blood through the placenta, a disk-like structure sticks to the inner lining of the uterus and connects to the fetus through the umbilical cord. Amniotic fluid and membrane cushion the fetus against bumps and shakes of the mother’s body.
Gestation lasts on average 280 days – about 9 months. When child is ready for a date, and contemporary president on the cervix, which begins to relax and expand to get ready for a child to pass in and through the vagina. Mucus plug, which was formed in relieving the cervix, and with amniotic fluid, comes through the vagina when the mother’s water breaks.
When you start the contractions of the work, and the walls of the uterus contract and is stimulated by the hormone oxytocin, the pituitary gland. And causes contractions of the cervix to widen and begin to open. After several hours of this widening, the cervix dilated (opened) enough for the child to come through. Pay the child out of the womb, through the cervix, and along the birth canal. The baby’s head usually comes first, and the umbilical cord comes out with the child, and disconnecting after the baby is delivered.
The final stage of the process of childbirth involves the delivery of the placenta, which is now called after the birth. After being sacked from the inner lining of the uterus, contractions of the uterus push it, along with the membranes and fluids.
Problems of the female reproductive system
Your daughter may experience reproductive system problems sometimes. Here are some examples of disorders that affect the reproductive system of women.
Problems of the vulva and vagina:
• vulva is an inflammation of the vulva and vagina. May be caused by irritating substances (such as laundry soap or bubble baths). May Poor personal hygiene (such as a survey from back to front after a bowel movement) can also cause this problem. Symptoms include redness and itching of the vagina and vulva and unloading areas, in some cases through the vagina. It can also be caused by inflammation of the vagina by an overgrowth of Candida, a fungus normally present in the vagina.
• Nonmenstrual vaginal bleeding is most commonly due to the presence of foreign body, vagina, and often stuffed up toilet paper. It may also be due to the decline of the urethra, a condition in which the mucous membranes of the urethra protrude into the vagina and the formation of small, donut shaped mass of tissue that bleeds easily. It can also be extended because of an injury (such as when the fall of the beam on a bike or frame) or vaginal trauma from sexual abuse.
• labial adhesions, and sticking together or holding small children in the midfield, and usually appear in infants and young girls. Although there are usually no symptoms associated with this case, it can lead to oral adhesions increase the risk of urinary tract infection. Sometimes topical cream is used to assist in the separation of estrogen minora.
Problems of the ovaries and fallopian tubes
• ectopic pregnancy occurs when a fertilized egg, or zygote, does not travel to the uterus, but instead grows rapidly in the fallopian tube. Women can develop this condition with severe abdominal pain, should consult a doctor for surgery may be necessary.
• Endometriosis occurs when tissue normally found only in the uterus begins to grow outside the womb – in the ovaries, fallopian tubes, or other parts of the pelvic cavity. It can cause abnormal bleeding, and painful periods, pelvic pain and the year.
Ovarian tumors •, although they are rare, can occur. Can girls with ovarian tumors and abdominal pain and masses that can be felt in the abdomen. There may be a need for surgery to remove the tumor.
• Ovarian cysts are noncancerous sacs filled with fluid or semisolid material. Although it is common and generally harmless, they can become a problem if a very large increase. Cysts may push on the large surrounding organs, causing pain in the abdomen. In most cases, the cysts disappear on their own and treatment is not necessary. If the cysts are painful, your doctor may prescribe a pill to change the growth, or may be removed by a surgeon.
• Polycystic ovary syndrome is a disorder of the hormone that said a lot of hormones (androgens) are produced by the ovaries. This condition causes the ovaries to become the expansion and development of many fluid-filled sacs, or cysts. Often appears for the first time during the teenage years. Depending on the type and severity of the condition, may be treated with drugs to regulate hormone balance and menstruation.
• Can ovarian torsion, or twisting of the ovary, occurs when the ovary becomes twisted because of disease or developmental abnormalities. Torsion blocks blood from flowing through the blood vessels that supply and nourish the ovaries. The most common symptom is lower abdominal pain. Surgery is usually necessary to correct them.
And can be for a variety of menstrual problems affecting girls, including:
• [Dysmenorrhea] is when a girl has painful periods.
• Menopause is when a girl has a very heavy periods with excess bleeding.
• Oligomenorrhea is wrong or when the wife and intermittent, although she was menstruating for a period of time but not pregnant.
• Menopause is when a girl did not start before the time the menstrual period is 16 years old or 3 years after the beginning of puberty, has not developed signs of puberty at the age of 14, or had normal periods but has stopped menstruating for a reason other than pregnancy.
Female reproductive tract infections:
• diseases transmitted sexually, these include infections and diseases such as pelvic inflammatory disease), human immunodeficiency virus / acquired immunodeficiency syndrome (AIDS), human papilloma virus (HPV or genital warts), syphilis, chlamydia and gonorrhea, and genital herpes. The most spread from one person to another through sexual contact.
• toxic shock syndrome, causes this disease is not common of toxins released into the body through a kind of bacterial infection which is more likely to develop if you leave beast in a very long time. It can produce high fever, diarrhea, vomiting, and shock.
If you believe that your daughter may be a symptom of a problem with the genital or if you have questions about growth and development, and talk to your doctor – many problems with the female reproductive system can be treated.
