A bit about anatomy

To understand the mechanism of delivery, it is necessary to know a little the anatomy of the female reproductive system. The female's internal sex organs are placed inside the pelvis, which is a bone wide ring in the form of a watering can. The pelvis is closely connected with the spine through the sacrum.

The uterus is the organ that protects and nourishes the fetus before birth. It is placed in the lowest part of the small pelvis and has the shape of an oblate pear with thick walls consisting of strong muscle fibers. The widest part of it, called the uterus, is located at the top, and the narrowest part, called the cervix, is directed downward and protrudes at the level of the vaginal vault, resembling the neck of the bottle. The cervix opens into the vagina with a hole called the external pharynx.

thank you for your position, the uterus is well protected from shock and shocks;As a result of the hanging position, and which supports strong ligaments, the uterus is provided with some degree of mobility. The loaded colon can move it forward, and the filled bladder - back.

The uterus, consisting of strong and tensile muscles, increases during pregnancy several times. During pregnancy, there is also a thickening of the muscle fibers and the formation of new uterine muscle cells. Thus, the body of the uterus in which the fetus is located can adapt to its growth and becomes able to expel the fetus at the time of delivery. The cervix is ​​designed to close the uterine cavity, preventing also the penetration of microbes into the uterine cavity from the vagina.

The vagina is a muscular-membranic canal about 7-8 cm long. It is reported in the upper part of the uterus with an opening in the cervix, and in the lower part is limited to the virgin pleura or its remains. The mucous membrane that lining the inner part of the vagina has a corrugated appearance, as a result of which, and also due to the great elasticity of the muscles of the vaginal wall, it is possible to stretch the vagina during sexual intercourse and during childbirth. External genitalia( large and small labia and clitoris) in childbirth have no special significance. The bottom of the small pelvis is a system of interconnected muscles and openings. Starting from the front, the first is the urethra( urethra), then the vagina and anus( anus).Try to do the following exercise( for details, see the exercise "kegal"): strain, as if you are urinating - this is a urethra. Now strain, as at the end of defecation( evacuation of the intestine) - it's the rectum. If you strongly squeeze both of these muscles, you will feel the muscles surrounding the vagina. And for childbirth, and for ordinary life, it is useful for a woman to maintain these muscles in shape. The following exercises will help you in this.
