Inani eliphezulu leeseli ezibomvu zegazi

Inani eliphezulu leeseli ezibomvu zegazi liwukwanda uhlobo oluthile lweseli ezenziwa emathanjeni futhi zitholakala egazini. Umsebenzi oyinhloko weseli ezibomvu zegazi ukususa ioksijini ephusheni kuye emzimbeni wonke. Isimo esivinela ioksijini singabangela ukwanda kwenani leeseli ezibomvu zegazi. Ezinye izimo zingabangela ukuba umzimba wenze iiseli ezibomvu zegazi ezingaphezu kwalokho okudingayo. Lokho okubhekwa njengenani eliphezulu leeseli ezibomvu zegazi liyahluka kuma-lab ahlukene. Kubantu abadala, izinga elijwayelekile ngokuvamile liyi-4.35 kuya ku-5.65 million red blood cells nge-microliter (mcL) yegazi kumadoda kanye ne-3.92 kuya ku-5.13 million red blood cells nge-mcL yegazi kwabesifazane. Ezinganeni, lokho okucatshangelwa njengokuphezulu kuncike ebudaleni nasebuhlangeni.

Amazinga a oksijini ephansi, ukusebenzisa kabi kwezidakamizwa ezithile kanye nomdlavuza wegazi kungabangela inani eliphezulu lamaseli abomvu egazi. Amazinga aphansi oksijini Umzimba ungenza amaseli abomvu egazi amaningi njengendlela yokuphendula izimo eziholela emazingeni aphansi oksijini. Lezi zingafaka: I-Congenital heart disease kubantu abadala I-COPD Ukwehluleka kwenhliziyo I-Hemoglobinopathy, isimo esikhona ekuzalweni esinciphisa ikhono lamaseli abomvu egazi lokuphatha oksijini. Ukuphila emazingeni aphezulu. I-Pulmonary fibrosis - isifo esenzeka lapho ilungu lemiphunga lilimazeke futhi libe namabala. I-Sleep apnea - isimo lapho ukuphefumula kuye kuphazamiseke futhi kuqale izikhathi eziningi ngesikhathi sokulala. Ukuqina kokunxuswa kwe-nicotine (ukubhema) Kwabanye abantu, umdlavuza noma izimo ezingaphambi komdlavuza ezihlasela u-bone marrow zingabangela ukuba amaseli abomvu egazi amaningi kakhulu enziwe. Isibonelo yi: I-Polycythemia vera Ukusebenzisa kabi kwezidakamizwa ukuthuthukisa ukusebenza kwezemidlalo Ezinye izidakamizwa zikhuthaza ukwenziwa kwamaseli abomvu egazi, okuhlanganisa: I-Anabolic steroids. Ukwenza igazi, okuthiwa futhi yi-transfusion. Izithombe zeprotheni eyaziwa nge-erythropoietin. Ukugxila okuphezulu kwamaseli abomvu egazi Uma ingxenye eyi-liquid yegazi, eyaziwa nge-plasma, iphansi kakhulu, inani lamaseli abomvu egazi libonakala liyakhuphuka. Lokhu kwenzeka ekuphumuleni kwamanzi. Noma kunjalo, amaseli abomvu egazi ahlanganiswe ngokukhulu. Inani lamaseli abomvu egazi lihlala lifana. Ukuphumula kwamanzi Ezinye izifo Ngokungavamile, kweminye imidlavuza yempilo noma ngemuva kokufakelwa kwempilo, amakilogremu angenza okuningi kwe-hormone erythropoietin. Lokhu kubangela umzimba ukuba wenze amaseli abomvu egazi amaningi. Inani lamaseli abomvu egazi lingaphezulu futhi esifweni se-nonalcoholic fatty liver disease. I-Nonalcoholic fatty liver disease Incazelo Isikhathi sokubona udokotela
