Female body: anatomy and physiology. Anatomy of the female reproductive system
The female body has long inspired artists, art historians, musicians, people of creative professions. No man can pass by a woman with a beautiful, proportional figure. What attracts the weaker sex? What is special about their anatomy?
Features of the structure of the female body
Women and men anatomically have certain similarities, but the signs of difference are much greater. The anatomy of the female organs has some differences from the male:
- external and internal sexual characteristics;
- dimensions and ligament apparatus of the pelvis.
Physiologically, the female mammary glands develop, and body shapes have a certain roundness. Due to the intensive production of hormones, the layer of subcutaneous tissue increases, which contributes to the formation of these roundness.In women, the predominant chest type is physique, and in men, it is the thoracic. Also different are erogenous zones. They contribute to increased sexual arousal.
Providing female breeding functions
The reproductive system of women is designed specifically to perform an essential function. It consists in the bearing and birth of offspring, the successors of the human race. All the organs of different systems of the female body are somehow involved in the implementation of this task. If for some reason a representative of the fair sex could not conceive and give birth to a baby at the reproductive age, then her various health problems can begin. The hormonal system suffers first.
After all, not just for many decades, experts have insisted that pregnancy in its normal course carries only positive moments. This is rejuvenation, renewal of blood, prevention of cancer, not to mention that after the birth of a child, a woman acquires moral satisfaction, a new meaning of life.
The anatomy of the female reproductive system is designed so that a woman can perform the function of procreation.Since the merger of germ cells, pregnancy begins. At the same time, significant physiological changes begin, which the female body undergoes. Its anatomy is such that without certain conditions, pregnancy will not come.
To fertilize an egg, the sperm must travel through the female genital organs, attach to it and “guess” the desired physiological phase. After all, pregnancy is possible only during the ovulation phase. Due to the formation of the corpus luteum, the level of progesterone helps the ovum to implant in the uterus wall, and also eliminates the possibility of miscarriage in the early stages.
The female body (its anatomy) is arranged very difficult. The internal organs of reproduction have four components: the vagina, the fallopian tubes, the uterus and the ovaries. The external anatomy of the female genital organs includes the pubis, the clitoris, labia (large and small), the vaginal opening, the hymen.
External genitals: female anatomy
The pubis is a triangular mound in the lower part of the abdomen, has a developed subcutaneous base (fat layer). The pubic part is covered with hairs.They move to the genital large lips (a round-shaped fold consisting of skin, connected by soldering). The hairs start growing at puberty of girls. Between the labia majora there are small, surrounding the beginning of the vagina, in which there are vaginal and urethral openings. The front ends of these lips clasp the clitoris.
The clitoris is a paired cavernous body. Top covered with skin with nerve endings. There are several parts in it:
- the body, which is closer to the front, narrows and ends with a head;
The hymen is also considered an external genital organ. It has the form of a film with holes, the secrets being produced pass through them. It plays the role of a septum (separates the external organs from internal).
Female internal organs
Difficult anatomy of the female body. With a photo illustrating the structure of the reproductive system, you can find in the article. It includes many elements. Now we consider the internal genital organs.
The vagina is a hollow organ, shaped like a tube. The upper part of the wall forms arches.They are divided by location (rear and front) and in directions (right and left). In front of the vagina in contact with the bladder and the channel through which urine is excreted. Behind it is adjacent to the rectum.
Experts note that a woman has 3 types of vaginal walls:
- Outdoor It consists of fiber, surrounding this component of the female reproductive system.
- Medium, also called muscular.
- Internal, which has a special structure (mucous membrane).
This organ has a special microflora. Its characteristics distinguish 4 degrees of purity:
- The first - sticks of epithelial structure, the environment is acidic.
- The second is a small number of sticks, the appearance of cocci, leukocytes. Wednesday does not change.
- The third - an alkaline environment is formed, the number of cocci and leukocytes increases.
- Fourth - pathogenic flora prevails.
With an unfavorable microflora, inflammatory processes occur that go to the overlying organs. Therefore, it is very important to monitor the purity of this body, to avoid hypothermia and frequent sexual contact with different partners.
The uterus is an important female organ with a triangular cavity, from the corners of which the fallopian tubes extend. The uterus is made up of muscles.One of the parts of the tube is located deep in the wall of the uterus - the interstitial part. Also allocate the narrow and extended parts. The enlarged area of the uterus ends in a funnel with fimbriae (fringe).
The shape of the uterus is like a flattened pear. In this body, the body is isolated, the top of which is the bottom. The isthmus is formed when the cavity narrows down. The lower region is the neck, which has a narrow cylinder shape. Inside the cervical canal forms, which passes into the internal and external pharynx.
Considering the female body, anatomy (science) allocates a paired organ - the ovaries. It is also an important element of the female reproductive system, because the childbearing function depends on it. The ovaries are almond-shaped and located on both sides of the uterus. Inside them there is a cortex containing follicles with different degrees of maturity. Every month a woman ripens eggs. Also, these organs perform the endocrine function, due to which secondary signs develop, and the body is prepared for carrying a fetus.
The physiological causes of female orgasm
The process necessary for conception and procreation is not only physiologically important, but also gives pleasure to a woman.The female body (the anatomy and composition of the tissues of the genital organs) has some peculiarities that make it possible to gain sexual satisfaction.
The urethra is surrounded by a network of blood vessels. In the process of sexual arousal, they are filled and there is a slight swelling through the uterine wall. Everyone knows such a thing as "Point-G". It is located approximately in the front upper part of the vaginal wall. With G-spot stimulation, many women get an orgasm, and some just enjoy it. The very nature of the woman is positioned so that the process of performing the main reproductive function takes place with pleasure. In the process of stimulation, a lubricant is released from the folds of the vagina. She wets his entire channel, thereby obstructing various rubbing and other problems.
There is also the concept of "muscle of love" (bosom-coccygeal). The muscle surrounds the vagina, anal passage and urethra. If it is good to train her, it will become the basis for successful sexual functioning. It has long been a simple exercise of geisha and heteras drove men crazy with their skills. These "priestesses of love" could bring their partners unearthly pleasure.These exercises include exercising the abdomen for about 2 minutes, imitating urinary retention, pulling in and tightening the buttocks, walking in that position, and so on.
Physiology of the fair sex
Female anatomy is closely related to the main functions of the female body. Each woman has certain cycles:
- Menstrual is a rhythmic repetition of the processes that prepare a woman for the onset of pregnancy. Repetitions occur due to the action of hormones: FSH (follicle-stimulating), LH (luteinizing) and LTG (luteotropic).
- The ovarian cycle has three phases. First, the follicle begins to grow and mature (follicular phase). When it has reached maturity, the follicle bursts, the ripe egg cell is released (ovulation phase). The follicle takes the formed yellow body.
- Uterine. The proliferation phase begins after desquamation (endometrial rejection). The lining of the uterus begins to epithelialize. The secretion phase occurs in the second half of the menstrual cycle.
Female anatomy and physiology are inextricably linked. Due to the close arrangement of the organs, all the processes occurring are carried out constantly and overlap.
Anatomy of the female pelvic organs
The structure of the pelvis plays a huge role in the generic process. Excrete muscles surrounding its bottom. They form layers that are strongly stretched in the process of labor and become like a wide tube, which is a continuation of the channel for this function. The muscles in the pelvis are elastic, able to keep all organs in the correct position and, consequently, to maintain women's health in good condition. The weakening of the muscles leads to the prolapse of the internal organs of the pelvis.
Blood supply to the female genitals
The anatomy of the female genital organs is arranged in such a way that it is supplied with nutrients through the uterine arteries extending from the ovarian vessels. All arterial vessels are accompanied by veins. Lymph drainage occurs through the lymphatic vessels.
