Kubandakanya imodeli yesibeleko esi-8 ukubonisa ukukhula kwe-umbungu kunye nombungu. 1. Inyanga yokuqala. 2. Inyanga yesi-2 yesi-3. Umbungu wenyanga yesi-4. Isibungwana senyanga yesi-4 (indawo eguqukayo) .5. Inyanga yesi-5 engekazalwa (indawo epholileyo) 6. Inyanga yesi-5 yosana olungekazalwa (indawo ejikelezayo). Inyanga engama-7.5 yamawele (isisu esiqhelekileyo) .8. Inyanga yesi-7 iwele elingekazalwa (indawo yesiqhelo) Isibeleko kunye neentsana zisuswe. nganye kwisandi.
Ukukhulelwa kubhekisa kwixesha lomzimba emva kokumitha ngaphambi kokubeleka. Ligama le-physiology, ekwabizwa ngokuba kukukhulelwa. Ihlala ithatha malunga neentsuku ezingama-266 ukusukela kwixesha lokuchunyiswa kweqanda eliqolileyo ukuya ekuzalweni komntwana. Ukulungiselela ukubala, ukukhulelwa kuhlala kubalwa ukusuka kusuku lokuqala lokuya exesheni, kwaye ukukhulelwa okupheleleyo malunga neentsuku ezingama-280 (iiveki ezingama-40). Ngexesha lokukhulelwa, imetabolism yoomama, inkqubo yokwetyisa, inkqubo yokuphefumla, inkqubo yemithambo, inkqubo yeemvakalelo, inkqubo ye-endocrine, inkqubo yokuzala, amathambo, amalungu, iigaments kunye namabele konke kwenzeka iinguqu ezifanayo.
Yonke inkqubo yokukhulelwa yahlulahlulwe yangamaxesha ama-3: ngaphambi kweveki ye-13 yokukhulelwa, ibizwa ngokuba kukukhulelwa kwangoko; iveki ye-14 ukuya kweyama-27 ibizwa ngokuba kukukhulelwa phakathi kwexesha; kwaye iveki yama-28 kwaye emva koko ibizwa ngokuba kukukhulelwa kade.
