Ukukhula komntwana-iiveki ezi-4 zokukhulelwa

Umxholo

• Ukukhula kombungu
• Ubungakanani bombungu kwiiveki ezi-4
• Ukukhulelwa kwakho ngekota

Kwiiveki ezi-4 zokumitha, ezilingana nenyanga yoku-1 yokukhulelwa, iiseli ezintathu zeeseli sele zenziwe zinika umbungu omde onobungakanani obumalunga ne-2 millimitha.

Uvavanyo lokukhulelwa lunokwenziwa ngoku, kuba ihoronic chorionic gonadotropin hormone sele ibonwa kumchamo.

Ukukhula kombungu

Kwiiveki ezine, iiseli ezintathu zeeseli sele zenziwe:

• Umaleko ongaphandle, okwabizwa ngokuba yi-ectoderm, oza kuguqula kwingqondo yomntwana, inkqubo yemithambo-luvo, ulusu, iinwele, iinzipho namazinyo;
• Uluhlu oluphakathi okanye i-mesoderm, eya kuba yintliziyo, imithambo yegazi, amathambo, izihlunu kunye namalungu okuzala;
• Uluhlu lwangaphakathi okanye i-endoderm, apho umphunga, isibindi, isinyi kunye nenkqubo yokwetyisa iya kukhula.

Okwangoku, iiseli zombungu osembindini zikhula ngobude, ngaloo ndlela zifumana ubume obude.

Ubungakanani bombungu kwiiveki ezi-4

Ubungakanani bomntwana ongekazalwa kwiiveki ezi-4 zokukhulelwa ungaphantsi kweemilimitha ezi-2.

Ukukhulelwa kwakho ngekota

Ukwenza ubomi bakho bube lula kwaye ungachithi xesha ujonga, sahlule lonke ulwazi oludingayo kwikota nganye yokukhulelwa. Ukweliphi ikota?

• Ikota yokuqala (ukusuka nge-1 ukuya kwiveki ye-13)
• Ikota yesi-2 (ukusuka nge-14 ukuya kwiveki yama-27)
• Ikota yesi-3 (ukusuka nge-28 ukuya kwiveki yama-41)
