The miracle ... Because how can we call the unimaginable fact that two cells unite to create a new life?
From conception to startNew life became established, and a close relationship was established between mother and fetus in anatomical sense. The ensuing period is the embryonic or ubiquitous the most important period of intrauterine development. Nothing more demonstrates its significance than the emergence of new life organs and organ systems. Development at this stage is determined by the quality, that is, the intensity and form of the prospective uterus, cells are rapidly differentiated, and they develop into tissues and organs.
The first trimesterThis period, which runs from the first day of the last menstruation to week 12, embryonic developmental age nevezzьk. If we divide the pregnancy into thirds (trimesters), this can be considered for the first third. The truth of the world is not yet obvious, as the size of the litter does not yet reach the level that can be easily perceived by others. and, in all respects, allow for proper growth and development. Following maturation, the development is a fertilized egg that resembles a blackberry with gradual structural structural preference folytatуdik. One area of the embedded bladder is in the direction of developing the lower flap, while another part is the first step in embryonic development. Embryonic node formation progresses in direction. burr discs result in formation. These discs form the basis for the development of the individual organ systems as they evolve. Hбrom plate: the kьltakarу the nervous system jelentхs rйsze fejlхdйsйnek alapjбt jelentх ectoderm, the kцtхszцveti system alapjбt jelentх mesoderm, йs the belsх bodies fejlхdйsйnek irбnyбt kijelцlх endoderm is that mennyisйgi tovбbbi fejlхdйs, differenciбlуdбs, minхsйgi йs small rйszben бtalakulбs rйvйn the embriу testйnek kialakulбsбt lehetхvй This will result in the transformation of these disks formation of the embryonic body, which is already recognizable in its sixth-seventh week following the last menagerie. However, the embryo's body proportions are quite unusual compared to the lower body proportions: its head is relatively large, and the size of the individual organs can still give the impression of imbalance.
Dimensions are absurd
Pregnancy can be examined with ultrasound
Maglхmaguge 5.5 centsOne third of pregnant women are close to a third vйrezgetйst during the first trimester of pregnancy. The most common form of bleeding is leathers from the lime-tree have become elevated kцvetkezmйnye. This process spontaneously heals in a significant number of cases, but can also lead to miscarriage with increased mailing. Blood during all pregnancies requires prompt medical examination, but in early pregnancy there is no therapeutic option for maintaining the pregnancy. The only recommended treatment is rest, observation. As a result, bleeding tends to decrease, and then cease when the increase in bleeding is detected, so that the chance of a spontaneous abortion of the pregnancy increases significantly. Various hormone levels and the efficacy of drugs have not been proven, and in addition, these therapeutic attempts can prevent the appearance of severely ill fetuses by preventing natural selection. Length approx. 9-10 cm, height 5.5 cm, its shape, its organs are fully recognizable, human. The next stages of his entire life are decisively marked by the growth and growth of quantity.
