Some 15 years ago, the word "vagina" caused bewilderment and even indignation among mankind. Many girls, still wanting to find out how the vagina works, were embarrassed to raise this issue so as not to seem ignorant. Interest in the body of a woman has always been, and today this topic is relevant and is discussed quite often.
It’s not a secret to anyone that anatomy is taught in educational institutions today . The structure of the female vagina in the classroom is understood including.
Female reproductive system. How is the vagina arranged?
The female reproductive system is divided into two types:
- external organs;
- internal.
What goes to the external organs
To study how a woman’s vagina works, you need to consider the structure of the entire reproductive system.
The organs of the external system are:
- pubis;
- large and small labia;
- clitoris;
- vestibule of the vagina;
- Bartholin glands.
Pubis
The girl’s pubis is the lower region of the anterior abdominal wall, which rises due to the subcutaneous fat layer. In this area, the presence of a pronounced hairline of color darker than the hair in other parts of the body is characteristic. Outwardly, it resembles a triangle, in which the upper boundary is outlined and the top is directed downward. In the pubic zone there are labia, which have skin folds on both sides, in the middle there is a genital fissure with a vestibule vestibule.
Small and large labia - what are these organs?
The labia majora can be characterized as folds of the skin where fatty tissue is located. The skin of this organ is endowed with many sweat and sebaceous glands, and during puberty, hair appears on it. In the lower part of the large lips there are Bartholin glands. In the period when sexual stimulation does not occur, the lips are in a closed position, creating protection against damage to the urethra and entry into the vagina.
Small lips are located between large lips, outwardly these are two skin folds of a pinkish tint. You can find another name - the organ of sexual feelings, because they contain many vessels, nerve endings and sebaceous glands. The small lips are connected above the clitoris, and a fold of skin is formed - the foreskin. During excitement, the organ becomes elastic due to blood saturation, as a result of which the entrance to the vagina narrows, this improves sensations during intercourse.
Clitoris
The clitoris is considered the most unique organ of the female reproductive system, it is located at the upper base of the small lips. The appearance and size of the organ may vary depending on the individual characteristics of the woman. Basically, the length varies within 4 mm, less often 10 mm or more. The function of an organ is to concentrate and accumulate sexual feelings; in an excited state, its length increases.
Vaginal vestibule
This organ is a slit-like region, which is bounded in front by the clitoris, on the sides by small lips, behind - by the posterior commissure of the labia, it is covered by a hymen from above. Between the clitoris and the entrance to the vagina is the external opening of the urinary canal, which opens on the threshold. This organ during sexual arousal is poured with blood and forms a "cuff", which produces vaginal lubrication and opens the entrance to the vagina.
Bartholin glands
The location of the glands - at the base and in the depths of the large lips, are of the order of 15-20 mm. In an excited state and during sexual contact, they contribute to the release of lubricant - a viscous grayish liquid rich in protein.
The internal reproductive system of organs
To understand how the female vagina works, you need to consider the internal genital organs as a whole and individually, each, this will give a clear picture of the structure of the organs.
Internal organs include:
- vagina;
- ovaries;
- fallopian tubes;
- the uterus;
- the cervix;
- hymen.
The vagina is an important organ
The vagina is an organ that takes part in sexual contact, also plays a large role at the birth of a child, since it is a component of the birth canal. On average, the size of the female vagina is 8 cm, but it can be smaller (up to 6 cm) and more up to 10-12 cm. The vagina has a mucous membrane inside with folds that allow it to stretch.
The device of the female vagina is made in such a way as to protect the body from all sorts of harmful effects. The walls of the vagina consist of three soft layers, the total thickness of which is about 4 mm, and each of them performs its own functions.
- The inner layer is the mucous membrane.
It consists of a huge set of folds, thanks to which the vagina can change its size.
- The middle layer is smooth muscle.
Muscular longitudinal and transverse bundles are present in both the upper and lower parts of the vagina, but the latter are more durable. The lower bundles are included in the muscles that regulate the work of the perineum.
- The outer layer is adventitia.
This is connective tissue, which is represented by elastic fibers and muscles. Advent function is the union of the vagina and other organs that are not part of the reproductive system.
Vaginal function:
This is the main function of the vagina, since it is directly involved in the conception of children. During unprotected intercourse, the sperm of a man, thanks to the vagina, enters the cervix. This makes it possible for the sperm to reach the tube and fertilize the egg.
The walls of the vagina, when connected to the cervix, form the birth canal, since during labor the fetus passes through it. During pregnancy, under the influence of hormones, the tissues of the walls become more elastic, which allows you to change the size of the female vagina and stretch it to such a size that the fetus can freely exit.
This is a very important function for the female body, since the vagina acts as a barrier due to its structure. With the help of the walls of the vagina, the body cleans itself, preventing the ingress of microorganisms.
With the help of the vagina, discharge is excreted as a result of the working capacity of the woman's body. As a rule, these are menstruation and transparent or whitish discharge.
For the microflora of the vagina to be healthy, it must be constantly moist. This is ensured by the internal walls, in which there are glands that secrete mucus. Allocations not only protect the body from the development of diseases, but also contribute to the painless course of sexual intercourse.
However, it is worth paying attention to the abundance of mucus secretions, it should not be excessive. Otherwise, consult a doctor.
Every girl should know how the vagina works, because this organ performs important functions.
Ovaries
These gonads contain about a million eggs, the formation of hormones estrogen and progesterone. In this organ, there is a change in the level of hormones and their release by the pituitary gland, due to which the eggs mature and exit the glands. This process is called ovulation and is repeated again after about 28 days. Close to each ovary is the fallopian tube.
What are fallopian tubes?
This organ is represented by two hollow tubes with holes that go from the ovaries to the uterus. At the ends of the tubes there are villi, which, in the process of the egg being released from the ovaries, help to capture it and direct it into the tube so that it enters the uterus.
Uterus
It is represented by a hollow organ having a pear-shaped shape and located in the pelvic cavity. The uterine walls are the layers of the muscles, so the uterus changes size with the fetus during pregnancy. During labor pains, the muscles begin to contract, and the cervix stretches and opens, and then the fetal egg passes into the birth canal.
This is a rather interesting question, how the vagina is arranged, because knowing the structure and functions of the woman’s genitals, you can clearly understand how the conception of a child begins, how it grows and is born.
Cervix
This organ is the lower part of the uterus with a passage that directly connects the uterus and the vagina. When the moment of birth comes, the walls of the neck become thinner, the pharynx increases and becomes a hole with a diameter of 10 cm, during this period the fetus can exit.
Hymen
Another name is hymen. The left side is represented by a thin fold of mucous membrane, which is located at the entrance to the vagina. Each girl has her own individual characteristics of the hymen. There are several holes in it, due to which blood is released during menstruation.
The hymen breaks during the first sexual contact, this process is called defloration. In this case, pain and blood secretion may occur. At a young age, the gap is less painful, this is due to the fact that after 22 years the pleura loses its elasticity. In some cases, the pleura remains intact, if it is too elastic, then the first sexual experience does not bring any discomfort. Hymen is completely destroyed only after childbirth.
The structure of the vagina of a virgin and a woman inside is not much different. As a rule, differences are just in the presence or absence of hymen.
It is generally accepted that the absence of a hymen indicates the presence of sexual activity in a girl, but this is not direct evidence. The film may be damaged as a result of heavy physical exercise, as well as during masturbation.
The structure of the whole human body is a whole science, which attracts more and more people every year. Mankind is interested not only in information about how the vagina is arranged, but also in other organs, because there are a lot of them in our body, and each of them is vital.
