Ukubala ixesha kwiinyanga?
Okokuqala, kuyimfuneko ukuqaphela into yokuba rhoqo ekuqaliseni ixesha eli lifazi lineengxaki. Into leyo kukuba abafazi abancinci ngenxa yobomi bentsebenzo bocansi abakwazi ukukhumbula ngokuqinisekileyo umhla xa bacinga ukuba ukukhulelwa kwenzekile. Ngenxa yeli qiniso, oogqirha bancike kwi parameter, njengenyanga nganye, xa beka umda wexesha. Isiqalo salo ngumhla wokuqala wexesha lokugqibela lokuhamba kwexesha. Ubude bexesha lokukhulelwa elisekwe ngale ndlela libizwa ngokuba yi-obstetric term.
Ukongezelela, kukho olunye uhlobo. Ukuze kube lula ukubala kweemathematika, inyanga nganye yekhalenda ithathwa ngqo kwiiveki ezi-4, kungekho, akukho ngaphantsi.
Ngaloo ndlela, unikezelwa ngokuqulunqwa kweziqulatho ezingentla, naluphi na umfazi okhulelweyo akayi kuba nzima ukuzibala ngokuzimelela ukuba zingaphi iinyanga lexesha leeveki ezingama-21 ukuya ku-22 zokukhulelwa. Ukwenza oku, ukwanele ukwahlula ngo-4. Ngenxa yoko, kuvela ukuba ngeli xesha leprogram ye-gestational, iinyanga ezi-5 kunye neveki ezi-1 okanye ezi-2 ezidlulileyo zidlulileyo ukusuka ekuqaleni, ngokulandelanayo. Kufuneka kuthathelwe ingqalelo ukuba iminyaka yangempela, okanye njengoko ibizwa ngokuba yi-embryonic period, iiveki ezimbini ngaphantsi. Loo mahluko uvela ekubeni kwimihla yokuqala kokuya esikhathini ukuya kwinyanga, apho ukuchumisa kweqanda kwenzeka khona, kuthatha iintsuku ezi-14.
Ukuze kwenziwe kube lula ukubeka ukuba zininzi kangakanani kule nyanga - iiiveki ezingama-21 zokukhulelwa, umfazi angasebenzisa itafile.
Umntwana ukhula njani ngeli xesha?
Xa sisebenzisana naziphi na iinyanga ezi zi-21 zeeveki zesiganeko, siya kuqwalasela utshintsho oluphambili olusenziwa ngumntwana onjalo ngaloo mhla.
Okokuqala, kufuneka kuphawulwe ukuba ngeli xesha lo mntwana ukhule kakhulu. Ngokomyinge, ukukhula komntwana ozayo ngeli xesha ukusuka phezulu ukuya kwisithende ngo-25 cm (18 cm ukuya kumsila ). Umzimba wayo ubunzima malunga ne-300 g.
Izikhumba zesikhumba zihlanganiswe nenani elikhulu leengxowa. Njengoko umzimba omncinci ukhula, baya kuhlanjululwa. Oku kutshintsha umbala wesikhumba, ngokubhekiselele kwenyuka kwinqanaba elincinci leoli. Ngoku i-tinge ebomvu.
Emlonyeni womlomo kubonakala ukuhlaziywa kwamazinyo, ukubunjwa kwesahluko sobuso bekrele kuyagqitywa: iimbumba, i-eyelashes zihluke kakuhle. Ngalesi xesha umntwana ubonakala ngokukhawuleza.
Inkqubo yokwenza iziko sele iphelile. Kule nqanaba, ziphucula kuphela. Iinjongo zesimiso se-endocrine, ezifana ne-pancreas, i-thyroid gland, i-adrenal gland kunye ne-pituitary gland, iyasebenza.
Ukuphuculwa komsebenzi we-CNS kuphawulwe. Ngalesi xesha umntwana sele sele edala ixesha lokuvuka nokuphumla.
Inkqubo yokutya isasebenza. Ukugqitywa kwe-amniotic fluid kudlula kuwo kwaye, ukuwela emathunjini, ifake kwi-meconium.
Umama olindelekileyo uvakalelwa njani ngeli xesha?
Ngeli xesha, oogqirha bancoma ukuba baphulaphule ngokunyamekela ukunyakaza komntwana. Ngokuqhelekileyo bavela ngenyanga yesine yokukhulelwa. Kodwa abaninzi, ngokukodwa oomama abanokuqala, baziva ngoku ngoku, kuba ukukhula kunye nokunyuka kwamaxesha.
Kunyuka ukwanda komzimba womfazi okhulelweyo. Ngalesi sikhathi ufumana u-4.5-6.5 kg.
Ngokubanzi, uluntu luqhelekile. Ukubonakaliswa kwe-toxicosis sele kusemva, kwaye ngoku ixesha elithulileyo xa ibhinqa liyakonwabela isikhundla sakhe.
