In form this organ is slightly curved, has a slight bulge, which is turned backward. Normally, the vagina should be placed in relation to the uterus so that their axes are aligned with each other at an angle of more than 90 degrees.
In the upper part of the vagina is somewhat wider than in the lower one. The front wall is at its edge to the bottom of the bladder, and is separated from it by a thick layer of loose fiber. The lower wall of the vagina is directly in contact with the urethra. The part of the back wall of the vagina is covered with the peritoneum and lies directly down to the rectum, moving away from it gradually in the area of the perineum.
What are the features of the structure of the vagina?
If we talk about how the vagina looks from the inside, then it should be noted that in its essence this organ is some space, bounded from all sides by walls.
The thickness of each wall varies within 3-4 mm. The main feature of this structure is the fact that due to its structure they can stretch, both in length and width. It is necessary, first of all, for the baby to pass almost unhindered through the birth canal. Moreover, the size of the vagina changes and immediately during sexual intercourse.
The color of the mucous membrane of the vaginal walls normally has a pale pink color. During the fetal gestation, in view of the increased blood supply to the pelvis and this area in particular, a discoloration may occur, and often the vagina acquires a bluish tinge.
How does the vagina look like a virgin?
At girls before the first sexual certificate or act the aperture of a vagina is covered with a hymen. This is nothing more than a fold of the vaginal mucosa. However, it does not completely cover the entrance to it. It itself has one or more holes, which are necessary for a monthly, unhindered passage of menstrual blood from the uterus.
It is also worth noting that, as a rule, virgins have slightly smaller sizes for virgins than for women. Its walls are more elastic and not so pliable. That is why quite often during the first intimate connection, the girls experience some painful sensations.
How does the vagina change before and after the birth of the baby?
Having told about how a healthy female vagina looks, we will dwell in more detail on what changes occur with this organ immediately before the appearance of the baby and after delivery.
So, with the onset of labor and the appearance of constant bouts, the woman's vagina gradually prepares for the passage of the baby through the birth canal. In particular, it sharply elongates, as if straightening the birth canal. This is achieved through the smoothing of numerous folds. At this time, the length of the vagina before birth can reach 18 cm and it looks like a straight, smooth tube.
After the appearance of the baby, the process of restoring the reproductive system of a woman begins. In this case, all the organs entering it, gradually begin to return to their previous state. If we talk directly about how the vagina looks after giving birth, then this body, as a rule, is greatly stretched. Walls of it often after passing through the birth canal of the baby are torn, which requires the imposition of special seams. For several weeks, the tissues of the vagina are somewhat swollen and may podkravlivat. That's why after the appearance of the baby a woman is examined daily in a gynecological chair, and in the presence of seams, they are processed.
