Female sexual organs (anatomy and physiology)

LARGE AND SMALL labia, clitoris , Venus' crest and virginal membrane (hymen). Large and small lips are two folds of skin. Out of big lips almost imperceptibly passes into the surrounding skin, thighs, and covered the following Pubert hair. Female lips are softer, and are located between the labia majora. Labia continue to the vagina and out into the great beyond. Female lips are pink because of the abundance of blood vessels, covered him ežnom skin. Front and rear, large and small lips on both sides come together and surrounded the vaginal vestibule. The point where the front lip of the clitoris (sikilj), which contains many blood cavities and plenty of nerve fibers. Virgin diaphragm, valve, the hymen is located between the labia at the entrance to the vagina. The hymen usually has a ring or crescent shape during the first sexual intercourse caused dissensions virgin membrane, which may be accompanied by the bleeding. If the hymen is rigid, inflexible, divisions may be higher, so the heavier bleeding. If the hymen is elastic, not performing any bleeding though its shape change after intercourse. In front of the pubic bone is after puberty subcutaneous fat pad, and the skin over it was hairy.This is called the Venus Crest. In large labia is a Bartholin gland. She can not see or can be felt if unchanged.Outlet channel and the glands are pouring into the vaginal vestibule (the inside of the labia). The mucus glands that moistens the vaginal vestibule, and its secretion is more abundant during sexual stimulation. He often performs as well as inflammation of the gland (bartholinitis), and the big lips, swelling occurs as a hen's egg, the skin of the area is warm and red. Inflammation of these glands causes other than severe pain, and fever. As a result of inflammation, may be closed outlet channel glands and cysts formed glands, tense elastic swelling. 

The vagina has the form of corrugated pipes behind the virgin membrane, ie. between it and the uterus. In a healthy vagina is whitish mucus in mild acid prevents germs to multiply in it. Many women are more abundant, slightly stronger vaginal discharge just before your period or after it. However, significant secretion of the so-called. white flowers, can be a sign of various diseases of internal female sex organs and a medical examination.It is usually caused by inflammation of the white flower of a vagina which can be easily cured drug or general treatment of women. Sometimes, if the inflammation of the vagina is often repeated, with the treatment of women should also treat the man as he passed again.

Womb has sploštene pear shape with the tip pointing downwards. Strengthened the ligaments in the middle of the pelvis. The uterus is a cavity that is lined with mucous membrane. In women, in adulthood, each month in materičnoj cavity lining swells, becomes thicker, it is prepared to accept a fertilized egg and that it feeds the first time. If pregnancy does not occur, ie. the fertilized egg does not implant in the lining, it peels, discarded, and monthly cleaning occurs, the bleeding - menstruation. Part of the uterus that protrudes into the vagina is called the cervix. The cervix is ​​outside the mouth of the uterus. The woman who gave birth outside the mouth is shaped cracks, and in such a barren spot.

CONNECTIONS uterus is supported in the middle of the pelvis can weaken, loosen, and the uterus descends, and can even turn the external genitalia. It occurs in women who are otherwise inclined descent and other organs (stomach, kidney, spleen), in women who raise heavy objects. The most common causes of damage and loosening the connection of the uterus, severe long-term birth without professional help, when the torn perineum. Lowering the uterus will occur also if the women early after giving birth hard work begins until the ligament of the uterus, stretched during pregnancy and childbirth in yet regained its original condition. Lowering the uterus exerts pressure and pain in the lower abdomen and lower back, feeling as if viscera would fall out. The most common problems with urination. A woman with coughing, exertion can not hold urine. Plastic surgery can remove the noise. During pregnancy the uterus growing and developing fetus. It protects it well, and itself is still protected by bony pelvic ring. The uterus during pregnancy increases 7-8 times. It is mostly made up of smooth muscle fibers. Or contraction of the muscle, contractions of the uterus pushes child from the body of women in childbirth. The cavity of the uterus, but the external opening to the workers, there are two openings to the fallopian tubes.

Tubes. They are located on the left and right sides of the uterus, and depart from its corners at the top. Take the form of tubes 10-12 cm long. On the outside are covered with peritoneum, as is the inner lining of which has a asps. Oviduct accepts j aj Asce which is maturing uj aj sure and transfer it into the uterine cavity. The inflammation usually causes tubal blockage of his mouth, sraštenja, and it prevents the transfer of eggs and the t0ga woman can get pregnant.

Ovaries. These are the female sex glands. They are located below the fallopian tubes on both sides of the uterus.In shape and size as the green almond. The ovaries have two roles. They are located about 200,000 eggs. In the age of sexual maturity of the individual eggs mature. If such a mature egg combine with male semen station, sperm, since it created a new being. The second task of the ovaries to produce juices called female hormones.Juices sexual glands, the ovaries secrete directly into the blood. Because the group of ovarian glands with internal secretion, which goes a thyroid gland in the neck, adrenal glands, testicles (testes) and others. Glands with external secretion than those with internal secretion, secrete juices right in the outlet channel, and through them in a particular organ or cavity of the body surface. Pituitary gland that secretes saliva, breast milk, liver, gallbladder, etc.. . . Juices glands with internal secretion, which flow directly into the blood called hormones.Hormones in the blood has very m alo, but their role is great. When the ovary starts to produce female sex hormones, changes occur throughout a woman's body (pre-teen, puberty, menstruation).

Fertilization in the ovary after the first period, ie. of puberty, eggs mature at regular intervals of 25-31 days.Immature egg matures in about 14 days and is released from the ovary. At the site of ejected eggs in the ovary is created called. luteum. Dumped egg fallopian tube and slowly accepts him transferred to the uterine cavity. The oviduct is a mature egg capable of fertilization for about 24 hours. What if it is fertilized in the fallopian tubes encounters with male seminal cells, sperm, and one of them gets into the egg and combine with it. After penetration of a sperm into an egg, as a rule, its membrane becomes impenetrable to others.

WHAT IS male sperm? Men's semen is mlječnobijela, compared with a man throw a 3-5 ml. It is located in 1 ml around 60 - 1 20 million seminal cells, sperm. Sperm-like tadpole, ie. snake head. They have a head, neck and long tail. Live sperm tail vibrates, it moves, so the sperm actively moving.

HOW in the ovary produces hormones? While the egg matures in the ovary, and 14 days after that, while it is yellow body, it produces hormones that prepare the lining of the uterine cavity to accept a fertilized egg. The lining of the uterus becomes thicker, full of blood and nutrients. When the fertilized egg comes from the oviduct into the uterine cavity, they implant in a thick mucous that coats and resulting pregnancies. This event inexplicably acts on the ovary that it does not decay luteum, but thrives and operates until the fourth month of pregnancy, while his role as the placenta takes over. Luteum in the ovary in early pregnancy creates a greater amount of hormones that soothe the uterus and promote its growth. During pregnancy, do not mature new eggs in the ovaries. Maturation of new eggs prevent large amounts of hormones in pregnancy the ovaries produce only the first, and later the placenta.

THAT IS NOT eggs capable of fertilization. If a mature egg is not fertilized within 24 hours, it shrivels, no longer capable of fertilization, and ruin. Swollen lining of the uterus, which was prepared to accept opiođenog egg is redundant. Given that there is no implantation of a fertilized egg in it, falls luteum in the ovary and turns into a scar. Due to the decline of yellow body reduces the amount of sex hormones in a woman's body, and the lining of the uterus shrivels and separates from the wall and peeled. It causes bleeding called menstruation, monthly cleaning, period, or menses (from the Latin word mensis = month). Menstruation is a miscarriage neoplođenog eggs. It is recommended that women accurately recorded the beginning and duration of menstruation, so that water. menstrual calendar. No women in the menstrual perform continuously at intervals of 28 days. Usually come early or late 1 -3 days. Account is always a space between the two first days of menstruation. Before you make your period has come to the expulsion of a mature egg from the ovary, creating a corpus luteum in the ovary where the egg was, and deterioration of the corpus luteum. If all of these changes have taken place, a woman is bleeding, but this is not abnormal menstrual bleeding. There is an easy way to determine whether the ovary released the egg and whether to create a corpus luteum before bleeding. It is known, namely, the corpus luteum produces a sex hormone (progesterone), which causes a slight rise in body temperature. Yellow body does not produce in the ovary, if it has not thrown a mature egg. If a woman is measured body temperature in the mouth or intestine guznom (in the vagina may be), always with the same thermometer, and this morning immediately after waking, before getting up and taking meals, and to write, so we get the curve. Bazaine temperature. About 10 - 1 4 days before menstruation temperature by 0.3 to 0.50 C (3 to 5 tenths of a degree) higher than the first days of the onset of menstruation. The increase in temperature occurs one to two days after the mature ovary released the egg.
