ʻO ka hāpai ʻana: nā mea huna o ka placenta

I ka wā hāpai, hana ka placenta ma ke ʻano he ea. He ʻano kahua no ka hoʻololi ʻana ma waena o ka makuahine a me ka pēpē. ʻO kēia kahi, hoʻomaikaʻi i kāna kaula, huki ka pēpē i nā meaʻai a me ka oxygen i lawe ʻia e ke koko makuahine.

Na ka placenta e hānai i ke keiki

ʻO ka hana nui o ka placenta, he ʻōpū ephemeral me nā mana kupaianaha, ʻo ia ka hānai. Hoʻopili ʻia i ka ʻōpū a hoʻopili ʻia i ke pēpē ma ke kaula ma o kahi vein a me ʻelua aʻaʻO kēia ʻano ʻōhuʻu nui i piha i ke koko a me ka villi kahi o nā hoʻololi a pau. Mai ka pule 8, hāʻawi ia i ka wai, nā sugars, amino acids, peptides, minerals, vitamins, triglycerides, cholesterol. Pilikino, ʻohi ʻo ia i ka ʻōpala mai ka pēpē (urea, uric acid, creatinine) a hoʻokuʻu iā lākou i loko o ke koko makuahine. ʻO ia ka puʻupaʻa o ka pēpē a me kona māmā, hāʻawi i ka oxygen a me ka hoʻokuʻu ʻana i ke kalapona kalapona.

ʻO ka placenta: he ʻano huila i hāpai ʻia e ka makuahine

Lawe ka placenta i ʻelua DNA, ka makuahine a me ka makua. ʻO ka ʻōnaehana pale ʻana o ka makuahine, ka mea maʻamau e hōʻole i ka mea ʻē iā ia, ʻae i kēia ʻano huila ... makemake nui iā ia. No ka mea, komo ka placenta i ka hoʻomanawanui ʻana o kēia hoʻololi ʻana i ka hāpai ʻana, ʻoiai ʻO ka hapalua o nā antigens i loko o ka pēpē he makua kāne. Ua wehewehe ʻia kēia hoʻomanawanui e ka hana a nā hormones makuahine, ka mea e hahai ai i kekahi mau keʻokeʻo keʻokeʻo e hiki ke hoʻoikaika i ka ʻōnaehana pale. He diplomat maikaʻi loa, hana ka placenta ma ke ʻano he pale ma waena o ka ʻōnaehana pale o ka makuahine a me ke keiki. A hoʻokō i kahi hana: e hui pu ole ko laua mau koko. Hana ʻia nā hoʻololi ma nā paia o nā moku a me nā villi.

Hoʻokuʻu ka placenta i nā hormones

ʻO ka placenta hana i nā hormones. Mai ka hoʻomaka ʻana, ma o ka trophoblast, kahi outline o ka placenta, hana ia i ka mea kaulana beta-hCG : hoʻohana ʻia kēia no ka hoʻololi ʻana i ke kino makuahine a kākoʻo i ka ulu maikaʻi ʻana o ka hāpai ʻana. Eia kekahi pākuʻi ka mea mālama i ka hāpai ʻana a hoʻomaha i ka ʻiʻo o ka ʻōpū, nā estrogens e komo i ka hoʻomohala kūpono o ka fetal-placental, placental GH (hormone ulu), hormone lactogenic placental (HPL)… 

Mālama ka placenta i kekahi mau maʻi

Hoʻokani ka placenta he hana pale ka pale ʻana i ka hele ʻana o nā maʻi maʻi a me nā maʻi maʻi mai ka makuahine i kāna pēpē, akā ʻaʻole hiki ke hele. ʻO Rubella, chickenpox, cytomegalovirus, herpes hiki ke komo i loko. ʻO ka maʻi maʻi pū kekahi, akā ʻaʻole nui nā hopena. ʻOiai ʻaʻole hiki ke hala nā maʻi ʻē aʻe e like me ka maʻi maʻi maʻi. A ʻoi aku ka maʻalahi o kekahi ma ka hopena o ka hāpai ʻana ma mua o ka hoʻomaka. E ʻoluʻolu e hoʻomaopopo i ka placenta hiki ke hele i ka waiʻona a me nā mea o ka paka !

Ma ka D-Day, kani ka placenta i ka makaʻala e hoʻomaka i ka hānau ʻana

Ma hope o 9 mahina, ua loaʻa kona lā, a ʻaʻole hiki iā ia ke hāʻawi i ka lako ikehu nui e pono ai. ʻO ka manawa kēia e hanu ai ka pēpē a hanai mai loko mai o ka ʻōpū o kona makuahine. a me ke kōkua ʻole mai o kona placenta hiki ʻole ke hoʻokaʻawale. ʻO kēia ka hana hope loa, hoʻouna ʻana i nā leka makaʻala i komo i ka hoʻomaka ʻana o ka hānau ʻana. Pono i ka pou, a hiki i ka hopena.
