DEFINITIONS
External genital organs of women have 2 functions, namely as the entrance of sperm into the woman's body and as a protector of the sex organs in the infectious organisms.
Female genital tract has holes associated with the outside world, so that disease-causing microorganisms can enter and cause infection of the womb. Microorganisms are usually transmitted through sexual contact.
Sex organs in forming a path (genital tract), which consists of:
Ovary (ovarian), produces eggs
Fallopian tubes (ovidak), the site of fertilization
Womb (uterus), where the development of the embryo to fetus
The vagina, is the birth canal.
OUTSIDE sex organs
External genital organs (vulva) is limited by the labium major (equal to the scrotum in men). Labium major consists of sweat glands and sebaceous glands (oil producing); after puberty, will be covered major labium hair.
Labium minor is located right next to the labium major of the hole and around the vagina and urethra.
Hole in the vaginal introitus and is called half-moon shaped area at the back called forset introitus.
If there is a stimulus, from the small channels in addition to introitus discharge (mucus) produced by glands Bartolin.
The urethra is located in front of the vagina and the exit hole where the urine from the bladder.
Labium minora left and right meet in the front and form a clitoris, which is a small protrusion of a very sensitive (similar to the penis in males).
The clitoris is covered by a fold of skin called preputium (same as the skin on the tip of the penis depat men).
The clitoris is very sensitive to stimulation and can become erect.
Labium major left and right meet in the back forming the perineum, which is a network among fibromuskuler vagina and anus.
The skin covering the perineum and labium mayo with skin on other body parts, that is thick and dry and could form the scales. While membrane on labium minora and the vagina is a mucous membrane, a layer which has a similar structure to the skin, but the surface remains moist because of fluid from blood vessels in the deeper layers.
Because the rich veins, the labium minora and the vagina was pink.
Vaginal orifice surrounded by himen (the hymen).
Himen strength varies in every woman, because it was the first time you had sexual intercourse, himen can tear or not.
THE sex organs
In normal circumstances, the vaginal wall behind the front and touch each other so there is no room inside the vagina unless the vagina is open (eg during the examination or during sexual intercourse).
In adult women, the vaginal cavity has a length of about 7,6-10 cm. The lower third of the vagina is a muscle that controls the center line of the vagina. Two-thirds of the vaginal muscles are located above and easily stretched.
Cervix (neck of the uterus) is located at the top of the vagina.
During the reproductive period, vaginal mucus layer has a surface wrinkled. Before puberty and after menopause, a layer of mucus becomes slippery.
The uterus is an organ shaped like a pear and is located at the top of the vagina.
The uterus is located behind the bladder and in front of the rectum, 6 and bound by ligaments.
Uterus is divided into 2 parts, namely the cervix and the corpus (body of the uterus). Uterine cervix is the bottom that opens to the vagina. The corpus is usually bent toward the front.
During the reproductive period, the length of the corpus is 2 times the length of the cervix. The corpus is a rich network of muscles that can spread to save the fetus. During the birth process, the wall muscles contract so the baby pushed out through the cervix and vagina.
A channel that allows the sperm through the cervix into the uterus and menstrual blood out. The cervix is usually a good barrier for bacteria, except during menstruation and during ovulation (egg release).
Channels in the cervix is narrow, so narrow that even during pregnancy the fetus can not pass. But on this channel delivery process will be stretched so that the baby can get through.
Cervical tract covered by mucus-producing glands. Mucus is thick and can not be penetrated by sperm but just before ovulation.
At the time of ovulation, the consistency of the mucus changes so that sperm can penetrate and there was conception (fertilization). In addition, at the time of ovulation, the mucus-producing glands in the cervix are also able to store sperm that live for 2-3 days.
These sperm can then move up through the body and into the fallopian tube to fertilize an egg. Therefore, sexual relations conducted within 1-2 days before ovulation can lead to pregnancy.
Layer in the corpus is called the endometrium. Every month after the menstrual cycle, the endometrium will thicken.
If no pregnancy occurs, the endometrium is released and there was bleeding. This is called the menstrual cycle.
Fallopian tube stretched 5-7,6 cm from the edge of the uterus to the ovary.
The tip of the left and right fallopian funnel shape so that has a larger hole so the egg fell into dalamnye when released from the ovary.
The ovary is not attached to the fallopian tube but hung with the help of a ligament.
Move the egg along the fallopian tube with the help of the cilia (hair tremor) and muscle in the tube wall.
If the cells in the tube with the sperm meets egg and fertilized, the egg is fertilized started splitting.
During 4 days, small embryos continue to divide while moving slowly down the tube and into the uterus.
Embryo and then attached to the uterine wall and this process is called implantation.
Each female fetus at 20 weeks gestation have 6-7 million oocytes (egg cells are grown) and when born will have 2 million oocytes.
At puberty, remains as much a beginning 300000-400000 oocyte maturation has become the egg. But only about 400 eggs that are released during her reproductive period, usually every 1 of the menstrual cycle an egg is released.
Thousands of oocytes that did not experience a gradual maturation process will be destroyed and finally the whole egg is lost at menopause.
Before released, the egg fell asleep on the folikelnya.
Sleep egg can not perform cellular repair processes, as usual, so the chances of damage to the egg cell line with increasing age of women. Therefore, chromosomal abnormalities or genetic disorders are more likely to occur in pregnant women at advanced age.
