ʻO ka mea nui loa no kahi keiki i hānauʻoleʻia i loko o ka'ōpū nui o ka placenta. Hānauʻia kēia'ōpū ma ka pūpū ma hope o ka huiʻana. A i ka hapalua hola ma hope o ka hānauʻana, waiho ka placenta i ka'ōpū.
ʻO ka placenta, a ma nā wahi o nā maka'āinana, hānai i ka'ōpiopio me ka oxygen, mau meaʻai, hōʻikeʻike i nā huahana, a hana hoʻi i kahi hana pale, palekana i ke keiki mai nā maʻi likeʻole a me nā meaʻona e hiki ke lawe mai ka makuahine i ka kōpū.
Ke hele nei ka placenta ma ke ala o ka hoʻonaʻauao, ke kūlana makua a me kaʻelemakule. I ke kumu mua, ua kapaʻia ka placenta he mele, a ma ka mahinaʻelua ua hana ia i ka placenta. Ma keʻano,ʻehā kūkelē o ke olaʻana o ka placenta eʻikeʻia i nā hebedoma : 0, I, II, a me III.
ʻO ia ke kumu ma kēlā me kēia o nā mea i hoʻolālāʻia o ke kumukū e nānā pono ke kauka i ka placenta a hoʻoholo i ka lōʻihi o kona oʻoʻana. Ma hope o nā mea a pau, kaʻaiʻana o ka pēpē, kona uluʻana a ua ola kona ola kino ma ia mea.
Ke kūlana o ka placenta 0
ʻO keʻano,ʻo ka lōʻihi o ke kūlana o ka placenta he meaʻole ia a hala nā hebedoma he 30. ʻO kēiaʻano o ka placenta e hōʻike ana i kēiaʻano olaola no ka pēpē e hana pono i kāna mau hana a hiki iā ia ke pale aku i ka nui me ka hiki.
Ma ke kaʻina o ke kūlana o ka placenta 0 kēia kikowaena heʻano like like me ka mea ma ke kahua mua o kona uluʻana.
Akā,ʻo ka'ōmakōʻana o ka placenta a me ka lohi i ke kūlana o kēiaʻano nui he kino. Ma hope o nā mea a pau, me ka uluʻana o ka'ōpū, e ulu aʻe ka placenta, a ināʻaʻole e loli a hiki i ka hebedoma 34, ua hana nā kauka i ka hōʻailona o "ka hopena o ka placenta." ʻO ka mea pōmaikaʻi, he mea nui loa kēia. ʻO nā wāhine i loaʻa i ka maʻi maʻi a loaʻa iā lākou kekahiʻano Rh'ē aʻe me kahi'ōpiopio e pili ana i keʻano o ka hopena, aʻo kēia uluʻana o ka placenta e hōʻike i ka hikiʻana o nā pilikia i ke kūkuluʻana o ke keiki.
Akāʻo ka mea nui no ka makuahine i ka wā o ka hāpaiʻana,ʻaʻole ia e hopohopo, hiki i nā kauka ke hana i nā mea hewa a kau i ka hōʻailona kūponoʻole. Mai hiki i kou hāpaiʻana a me ka hānauʻanaʻaʻole e hoʻonāukiuki iāʻoe.
