Impendulo yalo mbuzo othi: "Kungani embryonic period ubizwa nangokuthi germinal?"

Ukuze zalisa iqanda, isidoda has ukungena emzimbeni sowesifazane futhi ufika amashubhu fallopian, baphi besifazane ocansini amaseli. Egg ngokwabo zibonisa ezinye usesimweni Fort, ngoba embozwe ulwelwesi ekhethekile, elimelela kube umgoqo omkhulu Ukungena. Ngakho-ke, it is ithunyelwa lokushaya abangaphezu kwesigidi isidoda. Njengoba nje umuntu (2-3) of them was ngaphakathi eqandeni, isifika eziningi zamakhemikhali nezinto eziphilayo, amakhemikhali kanye izinqubo zemvelo kwakhiwa emva esekuficile Ukungena lwalo "ifasitela". Kusukela ngesikhathi isidoda zalisa iqanda, iqala umsebenzi omkhulu ukuthuthukiswa umbungu, ehlanganisa izigaba eziningana, enye yazo kuyosisiza ekuphenduleni lo mbuzo: "? Kungani embryonic period ubizwa nangokuthi germinal"

I ahlukahlukene entuthuko umbungu

I ahlukahlukene entuthuko umbungu okubhekiselwe trimesters, njengoba they cabangisisa izinkathi ezintathu ngokulandelana kwazo yentuthuko iqanda eselivundisiwe e umzimba zesifazane. Ngakho, sicabangela izici esigabeni ngasinye ukuthuthukiswa umbungu.

Predembrionalnaya esiteji. Njengomthetho, isikhathi kuba amasonto 2-3. Ngalesi sikhathi, le ndoda esizayo iqala cell division, futhi iqala ukuthuthela kwesibeletho, lapho unamathele omunye izindonga, wabhubhisa mucosa yayo ama-enzyme kanye ngokoqobo sikhule kuwo. Njengoba amaseli ahlukanako okungenzeka angabi nawo amandla indawo esiqondile futhi lamatshwayo womuntu senyanga yokuqala abakwazi ukuchaza ukuthi kungani-embryonic period ubizwa nangokuthi germinal.
Isigaba se-embryonic iqala ngesonto wesithupha sokukhulelwa. Umbungu kakade kuphenduke eziphilayo umbungu agcwele, njengoba yayenza zonke izinhlelo ezinkulu kanye nezinhlaka ingane. Yingakho-embryonic period ubizwa nangokuthi germinal.

isigaba kwengane iqala kwesonto lesishiyagalombili yokukhulelwa. Phakathi nenkathi yesithathu, i-embryo ibizwa ngokuthi i- "fetus" ( "humanoid"), njengoba usezuze kakade lamatshwayo umuntu. isigaba kwengane ihlala kuze kube umntwana wakhe esezelwe.

Ngo ngokwayo, ukuthuthukiswa umbungu kuholela yasemsebenzini kakhudlwana futhi kakhulu zonke izinhlaka futhi izinhlelo emtholile lona wesifazane okhulelwe. Lokhu kwenzeka ukuze kuqinisekiswe ukusebenza evamile fetus nokukhula. Isithelo Ubuye eziningi ezisebenza ngokubambisana ekhethekile ukumsiza ukuzivumelanisa ukusinda nangaphansi kwezimo ezingezinhle. Ngokwesibonelo, ukuthola lemali edingekile oxygen inani abomvu evusa umbungu cishe kabili Kuloko, ngokuphindwe kabili, futhi palpitation. Ukugeleza neyandisiwe igazi emzimbeni kamama emzimbeni ngokusebenzisa umzanyana wengane olunikezwa umsebenzi kakhulu inhliziyo nokuthumba owesifazane owayezithwele, nokunye.

Ngakho, singaphetha ngokuthi ukuthuthukiswa imithi akusho yima, minyaka yonke yenziwa okutholakele ezihlobene isimo abesifazane okumangalisayo ngesikhathi sokukhulelwa. Okuningi ngokoqobo 10 edlule, odokotela abazange landulele iyiphi okutholakele omkhulu ungenza, kungani embryonic period ubizwa nangokuthi germinal. Manje thina yakuthola izitho bathuthukise indoda isebenza, lokho izici it has ngezigaba yentuthuko obuhlukahlukene, nokuningi.
