How the vagina is structured: anatomy, structure and dimensions

Some 15 years ago the word "vagina" caused bewilderment and even indignation among mankind. Many girls, wishing to still find out how the vagina was arranged, were embarrassed to raise this issue, so as not to seem ignorant. Interest in the body of a woman has always been, and at the moment this topic is relevant and is discussed often enough.

It's no secret to anyone that today in the educational institutions anatomy is taught. The structure of the female vagina in the classroom, including.

Female reproductive system. How is the vagina?

The sexual system of women is divided into two types:

• External organs;
• Internal.

What goes in the external organs

To study how the woman's vagina is arranged, it is necessary to consider the structure of the entire reproductive system.

The organs of the external system are represented by:

• Pubis;
• Large and small labia;
• Clitoris;
• Vestibule of the vagina;
• Bartholin glands.

Pubis

The girl's forehead is called the lower region of the anterior abdominal wall, which rises due to the subcutaneous fat layer. This area is characterized by the presence of a pronounced hair color darker than hair on other parts of the body. Outwardly resembles a triangle, which is outlined by the upper boundary and directed downward to the top. In the pubic area are the labia, which have on both sides of the folds of the skin, in the middle there is a sexual slit with the vestibule vestibule.

Small and large labia - what are these organs?

Large labia can be described as folds of the skin, where the fatty tissue is. The skin of this organ is endowed with a lot of sweat and sebaceous glands, and at puberty, a hair covering appears on it. In the lower part of the large lips there are Bartholin glands. At a time when there is no sexual stimulation, the lips are in a closed position, creating protection from damage to the urethra and the entrance to the vagina.

Small lips are between large, outwardly it is two skin folds of a pinkish hue. You can find another name - the organ of sexual feelings, because they contain a lot of suds, nerve endings and sebaceous glands. Small lips join over the clitoris, thus the fold of a skin - an extreme flesh is formed. During excitation, the body becomes resilient due to blood saturation, as a result of which the entrance to the vagina narrows, this improves sensations in the process of sexual intercourse.

Clitoris

The clitoris is considered the most unique organ of the female's reproductive system, it is located at the upper base of the small lips. The appearance and size of the body can vary depending on the individual characteristics of the woman. In general, the length varies within 4 mm, rarely 10 mm or more. The function of the body is to concentrate and accumulate sexual feelings, in an excited state its length increases.

The vestibule of the vagina

This organ is a slit-like region, which is confined to the front by the clitoris, on the sides - by small lips, behind - by the posterior adhesion of the labia, from above is covered by a hymen. Between the clitoris and the entrance to the vagina is the external opening of the urinary canal, which opens on the threshold. This body during sexual excitement is filled with blood and forms a "cuff", which produces vaginal lubrication and opens the entrance to the vagina.

Bartholin's glands

Location of the glands - at the base and in the depth of large lips, have a value of the order of 15-20 mm. In an excited state and with sexual contact contribute to the release of lubricant - a viscous grayish liquid, rich in protein.

Internal organ reproductive system

To understand how the female vagina is arranged, it is necessary to consider the internal sexual organs as a whole and individually each, this will give a clear picture of the structure of the organs.

To internal organs carry:

• vagina;
• Ovaries;
• Fallopian tubes;
• The uterus;
• Cervix of the uterus;
• Hymen.

The vagina is an important organ

The vagina is an organ that takes part in sexual intercourse, and plays an important role in the birth of a child, since it is a constituent 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 larger - up to 10-12 cm. The vagina has a mucous membrane inside it 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 fulfills its functions.

• The inner layer is the mucous membrane.

It consists of a huge number of folds, thanks to which the vagina can change its size.

• The middle layer is smooth muscle.

Muscular longitudinal and transverse fascicles are present both in the upper and lower parts of the vagina, but the latter possess greater strength. Lower beams are included in the muscles that regulate the perineum.

• The outer layer is adventitia.

It is a connective tissue that is represented by elastic fibers and muscles. The function of adventitia is the union of the vagina and other organs that are not part of the reproductive system.

Functions of the vagina:

• Sexual.

This is the primary function of the vagina, as it takes a direct part in the conception of children. During unprotected intercourse, sperm men get into the cervix by the vagina. This allows the sperm to reach the tube and fertilize the egg.

• Generic

The walls of the vagina, when connected to the cervix, form a birth canal, since during fights the fetus passes exactly along it. During pregnancy, under the influence of hormones, the tissue walls become more elastic, which allows you to change the size of the female vagina and stretch it to such a size that the fruit can go out without hindrance.

• Protective.

This is a very important function for the female body, because the vagina acts as a barrier due to its structure. With the help of the walls of the vagina self-cleaning of the organism takes place, preventing the ingress of microorganisms.

• Inconductive.

With the help of the vagina, excretions are excreted as a result of the working capacity of the woman's body. As a rule, these are menstruation and clear or whitish discharge.

To the microflora of the vagina was healthy, it must be constantly moist. This is provided by the internal walls, in which there are glands secreting mucus. Allocations not only protect the body from the development of diseases, but also contribute to the painless course of sexual acts.

However, one should pay attention to the abundance of mucus secretions, it should not be excessive. Otherwise, consult a doctor.

Each girl should know how the vagina is arranged, because this body performs important functions.

Ovaries

This sex gland contains about one million eggs, there is also the formation of hormones of estrogen and progesterone. In this organ there is a change in the level of hormones and their release by the pituitary gland, which ripens the eggs and leaves the glands. This process is called ovulation and is repeated about 28 days later. 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 pipes there are villi, which during the release of the ovum from the ovaries help to seize it and send it to the tube to get into the uterus.

Uterus

It is represented by a hollow organ, which is pear-shaped and located in the pelvic cavity. Uterine walls are layers of muscles, so during the pregnancy the uterus changes its size along with the fetus. During birth, 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 of how the vagina is arranged, because knowing the structure and functions of the sexual organs of a woman, one can clearly understand how the conception of a child begins, how it grows and appears.

Cervix

This organ is the lower part of the uterus with a passage that connects directly to the uterus itself and to the vagina. When the moment of childbirth arrives, the walls of the neck become thinner, the shed grows and becomes an opening with a diameter of 10 cm, during this period, the fetus can exit.

Hymen

Another name is hymen. Pleva is represented by a thin fold of the mucosa, which is located at the entrance to the vagina. Each girl has her own individual characteristics of a hymen. It has several openings, through which blood is released during menstruation.

The hymen is broken at the first sexual contact, this process is called defloration. In this case, there may be pain and blood liberation. At a young age, the rupture is less painful, this is because after 22 years the spittle loses its elasticity. In some cases, the plum remains intact, if it is too elastic, then the first sexual experience does not bring any discomfort. Hymen is destroyed completely only after childbirth.

The structure of the vagina of a virgin and a woman from within is not much different. As a rule, the differences are just in the presence or absence of the hymen.

It is generally believed that the absence of a hymen indicates the existence of a girl's sexual life, but this is not direct evidence. The film can be damaged by heavy physical exercises, as well as during masturbation.

The structure of the entire human body is a whole science, which every year attracts more and more people. Humanity is interested not only in information about how the vagina is arranged, but also in other organs, because there are many of them in our body, and each of them is vitally important.
