Ukusebenza komzimba wesifazane kuyinkimbinkimbi kakhudlwana kuneyabantu, ngoba umsebenzi wayo uxhomeke ekulinganeni kwe-endocrine. Isibonelo, isimiso se-hematopoietic sinethonya elikhulu ku-hematopoiesis. Ngakho-ke, ukujwayelekile kwe-hemoglobin kwabesifazane akuhlali njalo njalo futhi kuyahlukahluka ngezikhathi ngezikhathi kuye ngokuthi usuku lokuya esikhathini , ukuba khona kokukhulelwa.
I-norm of hemoglobin ekuhlaziyweni kwegazi kwabafazi kunqunywa kanjani?
I-hemoglobin ye-pigment ye-Organic iqukethe insimbi namaprotheni. Akapheleli nje kuphela ngokunikeza igazi elibomvu, kodwa futhi nokuthutha umoya-mpilo. Ngemuva kokuphuma kwamanzi emzimbeni, i-oxymoglobin yenziwa. Ijikeleza egazini legazi, ihambisa oksijeni ezithombeni nasezicukheni. Ngemuva kokudilizwa kwama-molecule wegesi, i-carboxyhemoglobin ekhona emithonjeni ye-biological biological etholakala.
Ukuze unqume ukuthi i-hemoglobin iyini emzimbeni, ukuhlolwa kwegazi kwenziwa kwabesifazane, okubandakanya ukubala inani eliphelele le-pigment eziphilayo kuma-capillaries noma emithanjeni.
Iyini izinga elivamile le-hemoglobin egazini labesifazane?
Ukugxila kwengxenye ehlolwe ye-erythrocyte akuxhomeki kuphela kwezocansi, kodwa futhi nangeminyaka yobudala:
- Ngakho-ke, kubantu besifazane abavamile, izindinganiso ezivamile ze-hemoglobin zivela ku-120 kuya kwangu-140 g / l.
- Amazinga aphezulu kakhulu awuphawu lwabantu ababhema (cishe 150 g / l) nabagijimi (kufika ku-160 g / l).
- Okuqukethwe okuncane kakhulu kwe-hemoglobin kubonakala kwabesifazane abadala kuneminyaka engama-45-50 - kusuka ku-117 kuya ku-138 g / l.
Kufanele kuqaphele ukuthi izindinganiso ezichazwe nazo zithonywa ngosuku lokujikeleza kokuya esikhathini. Iqiniso liwukuthi ngesikhathi sokuya esikhathini, umzimba wesifazane ulahlekelwa igazi futhi, ngokufanele, insimbi. Ngakho-ke, ngokushesha ngemva kokuphela kokuya esikhathini, inani le-hemoglobin ebulili obuhle lingancishiswa ngama-5-10 amayunithi.
Isimiso se-hemoglobin esiphelele egazini labesifazane abakhulelwe
Ukubeletha umntwana kuhilela izinguquko ezinkulu emzimbeni, okuthinta kokubili isizinda se-hormonal kanye nesistimu ye-hemopoietic.
Esikhathini sokuqala sokuqala kokukhulelwa, ukushintsha okuphawulekayo ekujuleni kwe-hemoglobin akufanele kwenzeke. Ngokuvamile, izindinganiso ezijwayelekile zibekwe ebangeni kusukela ku-105 kuya ku-150 g / l.
Izinguquko eziphawulekayo enani lezinhlayiyana eziphilayo ezibuzwayo zivela kusukela ekuqaleni kwe-trimester yesibili. Lokhu kuchazwa ukuthi, ngokukhula kwe-fetus, inani eliphelele lokujikeleza igazi emzimbeni womama wesikhathi esizayo landa ngamaphesenti angama-50, ngoba uhlelo lwegazi phakathi kwabo nomntwana lungomunye wababili. Kodwa inani le-hemoglobin alikhuphuki, ngoba umnkantsha wamathambo awukwazi ukukhiqiza lezi zingubo ezibonakalayo ekukhuleni okukhudlwana. Kumele futhi kuqaphele ukuthi insimbi equkethe i-hemoglobin manje isetshenziselwa ukwakheka kwe-embryo kanye ne-placenta nxazonke. Ngakho-ke, omama bakamuva bayelulekwa ukuba baqaphe ngokucophelela ukusetshenziswa kokudla okunezinsimbi noma amavithamini enalesi sici. Emva kwakho konke, lapho ufeza izidingo
Ukucabangela amaqiniso angenhla, izinkambiso zenxenye echazwe ngamaseli abomvu awakhulelwe abesifazane abakhulelwe baqala kusuka ku-100 kuya kwangu-130 g / l.
Yiqiniso, ukubaluleka okuqondile kwe-hmoglobin evamile kumama ngamunye wesikhathi esizayo kunomuntu ngamunye futhi kuxhomeke eminyakeni yobudala, isimo sempilo yomfazi, inani lezithelo (emibungu engu-2-5, i-hemoglobin iphansi kakhulu kunejwayelekile). Futhi kuthinta inkambo yokubeletha, ukutholakala kwezifo ezingapheli zesistimu yokujikeleza kanye nezinkinga zokukhulelwa.
