Morfoanatomicheskoe difference between the two sexes has a specific name.In biology, this phenomenon is called sexual dimorphism.Thus the anatomical and physiological differences men women are quite extensive, due to the genetic material, in particular, having two X-chromosomes sexual type.This feature is the first, it is manifested at the level of the zygote.In fact, this means that at the level of a single cell from which an embryo develops later, you can judge the sexual difference.However, it appears only at the level of the genetic material.
anatomical structure of the female body
biological role of women in the human population - is pregnant with a child and childbirth.Accordingly, the system of the woman are maximally adapted to make the process.In the anatomical structure is to provide the genitals.Because of differences in the structure and functioning physiology floors differ.
Among female genitals there is a division in the interior and exterior.The internal organocomplexes are gonads, fallopian tubes, uterus, vagina.The first is iron with mixed secretion since they synthesize and germ cells, and sex hormones, which have a physiological effect on the entire body of women.The uterus is the organ in which the fetus is developing all the time.Some time after fertilization in the fallopian tube vial egg remains in its cavity.The delay in this anatomical structures lead to ectopic pregnancy, child bearing structure which does not provide for a woman's body.Therefore, when such complications of pregnancy or recommended her termination or embryo transfer, although this complex operation.
The uterus is a muscular organ, actively sprawling during gestation.It has set, the body and the neck forming the female genital tract.According to him the male sex cells invade the original extension of the fallopian tube, where the fertilized egg.
structure of a woman's body is subject to important biological system in which nature provides all the opportunities for development of the fetus, as well as for labor.The main anatomical structure that actually forms the birth canal, is the vagina.This hollow organ located in the pelvis and its walls limit the mobility of the fetal head at birth.
structure of the female body: the vulva
to the outer genitals attributed breasts, large and small labia.The logic of nature that shaped the structure of women in the process of phylogeny, is also the possibility of feeding a newborn baby high-energy product that is the secret of the breast - human milk.The process of allocation is subject to physiological changes in the body of women.During pregnancy, cancer develops, and from secretory departments begin to form ducts converging in the nipple area.It is controlled by the hypothalamic-pituitary system and the hormone prolactin.Once the woman produces a child into the world, started the process of lactation, ie the allocation of milk.Solely due to a child can be fed for several months, and then you need to start using it in the diet of porridge instantons.
structure of the female body also includes auxiliary genitals placed outside.It labia.Their function is to protect the vestibule from the penetration of pathogens.In the labia lips are special exocrine glands.They secrete aromatic secret.His need for modern social conditions are not taken into account, since the development of the second received signal system of the person.Previously, the secret of these glands served verbal signal readiness to mate.It is noteworthy that the structure of the female body does not differ only the sexual organs, and has its own characteristics in body, thought patterns, nature.
