Yankho la funso: "N'chifukwa chiyani nthawi embryonic umatchedwanso germinal?"

Kuti manyowa dzira, umuna kuti alowe mu thupi mkazi ndi kufika kwa Ukalawu, ali mkazi maselo kugonana. Dzira okha kuimira ena semblance linga, chifukwa iwo ataphimbidwa ndi Kakhungu wapadera, chomwe chimayimira chotchinga yaikulu malowedwe. Choncho, watumidwa gulu umuna zoposa wani miliyoni. Mwamsanga pamene munthu (2-3) a iwo anali mkati dzira, izo zimatengera ikani angapo mankhwala ndi kwachilengedwenso, mankhwala ndi njira thupi kuti anapanga pambuyo kutsekera malowedwe ake mu "windo". Kuyambira nthawi umuna manyowa dzira, imayamba nthawi ya chitukuko cha mwana wosabadwayo ndi, wopangidwa mwa magawo angapo, mmodzi amene kutithandiza kuyankha funso lakuti: "N'chifukwa chiyani nthawi embryonic umatchedwanso germinal"

Magawo chitukuko Ndisanaumbidwe

Magawo chitukuko cha mwana wosabadwayo lotchedwa trimesters, popeza amasonyeza nthawi zitatu zotsatizana chitukuko cha dzira m'thupi la mkazi. Motero, tikambirana makhalidwe a lililonse siteji ya chitukuko wosabadwayo.

Predembrionalnaya siteji. Monga ulamuliro, nthawi ya masabata 2-3. Nthawi imeneyi, munthu tsogolo akuyamba magawano selo, ndipo wayamba kusuntha kwa chiberekero, kumene Ufumuyo imodzi makoma, kuwononga mucosa ake secrete michere kwenikweni kukula mu izo. Popeza maselo kugawa alibe malo enieni ndi maphunziro a anthu trimester kufotokoza chifukwa nthawi embryonic umatchedwanso germinal.
Mbali embryonic akuyamba ndi sabata chimodzi mimba. Ndisanaumbidwe kale kutembenukira mu zonse kunachitika Ndisanaumbidwe moyo, pamene iye anapanga dongosolo lalikulu onse ndi ziwalo za mwanayo. Ndicho chifukwa nthawi embryonic umatchedwanso germinal.

siteji yoopsa akuyamba ndi sabata chitatu wa mimba. Pa nthawi yachitatu, Ndisanaumbidwe amatchedwa "mwana wosabadwayo" ( "yotha"), monga kale ankalankhula maphunziro a munthu. siteji yoopsa kumatenga mpaka pamene mwana wabadwa.

Palokha, chitukuko cha Ndisanaumbidwe munthu kumabweretsa m'manja ndi zambiri tima ntchito ziwalo zonse ndi machitidwe wa mayi oyembekezerayo. Izi zimachitika pofuna kugwira ntchito wabwinobwino wa mwana wosabadwayo ndi kukula. zipatso komanso amagwiritsa ntchito njira yapadera kuti amuthandize kuti azolowere moyo zinthu chowawa. Mwachitsanzo, kupeza zofunika kuchuluka kwa mpweya chiwerengero cha magazi wofiira Aukitsa Ndisanaumbidwe pafupifupi kawiri chifukwa cha zomwe, ndi kawiri, ndipo palpitation. The nakweza nthenda yotaya magazi kwa thupi la mayi kuti thupi kudzera chingwe umbilical wa mwana operekedwa ndi ntchito tima ya mtima wa mkazi wapakati, ndi zina zotero.

Choncho, tinganene kuti chitukuko cha mankhwala si kuima, ndi chaka ndi apeza zinthu zambiri zokhudzana ndi boma la akazi chidwi pa mimba. More kwenikweni zaka 10 zapitazo, madokotala chiyani kuoneratu atulukira aliyense wamkulu akhoza kupanga, chifukwa nthawi embryonic umatchedwanso germinal. Tsopano, tidapeza mmene ziwalo azitha kugwira ntchito munthu, zimene zimaonetsa kuti ali mu osiyanasiyana magawo chitukuko, ndi zambiri.
