I ka manawa he 21 mau manawa o ka hāpaiʻana, e like me keʻano o ke anatomy o ka pēpē e like me keʻano o ke keiki ma hope o ka hānauʻana. Ua loaʻa iā ia nā'ōpū āpau a me nā pūnaewele, a i ka wā e hiki mai ana wale nō ka uluʻana a me ka uluʻana. A no laila he 21 mau lā - ka hopena hope no ka mea hōʻikeʻelua - ke aʻoʻana i nā mea a pau o ka'ōpū e ho'āʻoʻia ai no ka hikiʻana o nā pōʻino hanaʻole.
ʻO ka Hanauma Hanau 21 - ka uluʻana o ka'ōpiopio
Ma ke 21 hebedoma o ka'ōpū,ʻaʻole i maʻalahi ka kaumaha a me ka nui o ka'ōpane no ka nānāʻana -ʻo kēia nā hōʻailona hōʻikeʻole, akā ke piʻi ka lōʻihi i 18cm aʻo ke kaumaha he 300 g.
A hiki i kēlā manawa, pono ka wahine ke manaʻo i ka neʻeʻana o ka'ōpiopio , ināʻaʻole i hiki i ka 21 hebedoma - hiki i kēia ke kumu e hopohopo ai.
ʻO ka hebedoma 21 - nā hōʻailona hōʻike o ka'ōpiopio
I nā 21 hebedoma, e like me ke kaʻina, kokoke i nā iwi a pau, nā'ōpū āpau a me nā nui kūpono o ka hānai. ʻO ka nui o ka nui o ka pēpē i ka hebedoma 21 he paʻipaʻi (51.6 mm ma waena o nā iwi iwiʻelua),ʻo ka lua o ke poʻo i ka lālani mua (64 mm),ʻoiai keʻano o ka lolo e like me kahi keiki hānau.
I ka hebedoma 21, ua anaʻia nā iwi a pau loa, akā:
- ka lōʻihi o ka'ūhā - 35.3 mm;
- ka lōʻihi o ke humerus - 33.5 mm;
- ka lōʻihi o ke tibia - 31.7 mm;
- ʻo ka lōʻihi o nā iwi o ka mua he 29.5 mm.
ʻO ke anawaena o ka umauma i nā hebedoma 21 he 46.4 mm,ʻo ka nui o ka puʻu o ka pēpē he 21.2 mm ke anawaena, 21.5 mm ka loa, aia nā lumi a pau o ka puʻuwai,ʻo kona mau kinipōpiko rhythmic, me ke alapine o 120-160 mau minuke.
ʻO ka anawaena o ka'ōpū i nā hebedoma 21 he 52.5 mm,ʻike maopopoʻia ka'ōpū,ʻaʻole i hoʻokiʻekiʻeʻia nā puka o nā'ōpū, ua piha ka paia o ka'ōpū.
Hiki keʻikeʻia nā puʻupaʻaʻelua i ka 20.3 mm ka lōʻihi, 11.1 mm āpau, nā ipu a me ke pelvisʻaʻole i hoʻolālāʻia, ua liʻiliʻi ka'ōpū ma ka pelvis, ma hope o ka hoʻouluʻana i ka'ōpiopio, aneane hikiʻole keʻikeʻia.
ʻO ka wahine i ka hebedoma 21 o ka'ōpū
ʻO ke kūlana o ka'ōpiopio ke poʻo, akā, ināʻo ka liʻiliʻi, i kēia manawa e hiki ke huli ke keiki i ka lā i loko o ka pūpū, a no laila, a hiki i ka 30 mau wiki o ka hānauʻana,ʻaʻohe mea e hopohopo ai.
ʻO ka placenta heʻaʻahu, 25,6 mm ka mānoanoa,ʻo ka mānoanoa o ke kolamu o ka wai amniotic i kahi kaʻawale mai nā'āpana o ka'ōpū mai 35 a 70 mm. Hoʻopauʻia ka pūpū i kēia manawa.
