I-oksijeni akuyona nje enye yezinto ezivame kakhulu zamakhemikhali emhlabeni, kodwa futhi ibaluleke kakhulu empilweni yomuntu. Siyithatha kalula. Kunalokho, sazi okwengeziwe ngempilo yosaziwayo kunento esingeke sikwazi ukuphila ngaphandle kwayo. Lesi sihloko sinikeza amaqiniso mayelana nomoya-mpilo okungenzeka awuwazi.
Asiphefumuli umoya-mpilo kuphela
Umoya-mpilo wenza ingxenye encane kuphela yomoya. Umkhathi womhlaba ungu-78% we-nitrogen kanye ne-oxygen engu-21%. I-nitrogen nayo ibalulekile ekuphefumuleni, kodwa umoya-mpilo usekela ukuphila. Ngeshwa, izinga le-oxygen emkhathini liyehla kancane ngenxa yokukhishwa kwe-carbon dioxide.
Umoya-mpilo wenza izingxenye ezimbili kwezintathu zesisindo sethu
Uyazi ukuthi u-60% womzimba womuntu ungamanzi. Futhi amanzi akhiwa i-hydrogen nomoya-mpilo. Umoya-mpilo unzima kune-hydrogen, futhi isisindo samanzi sibangelwa ikakhulukazi umoya-mpilo. Lokhu kusho ukuthi u-65% wesisindo somzimba womuntu umoya-mpilo. Kanye ne-hydrogen ne-nitrogen, lokhu kwenza u-95% wesisindo sakho.
Ingxenye yoqweqwe lomhlaba yakhiwe umoya-mpilo
I-oksijeni iyisici esigcwele kakhulu oqweqweni lomhlaba, ibalwa ngaphezu kwama-46% obunzima bawo. Amaphesenti angama-90 oqweqwe lomhlaba akhiwe ngezinto ezinhlanu: umoya-mpilo, i-silicon, i-aluminium, insimbi ne-calcium.
Umoya-mpilo awushi
Ngokuthakazelisayo, umoya-mpilo ngokwawo awubasi kunoma ikuphi ukushisa. Lokhu kungase kubonakale kungenangqondo, ngoba umoya-mpilo uyadingeka ukuze kuqhume umlilo. Lokhu kuyiqiniso, i-oxygen iyi-oxidizing agent, yenza ezinye izinto zivuthe, kodwa ayizishi.
O2 kanye ne-ozone
Amanye amakhemikhali, abizwa ngokuthi i-allotropics, angaba khona ngezindlela eziningana, ahlanganiswe ngezindlela ezahlukene. Kunezinhlobo eziningi ze-oxygen. Okubaluleke kakhulu i-dioxygen noma i-O2, okuyilokho abantu nezilwane eziphefumulayo.
I-ozone iyi-allotrope yesibili ebalulekile yomoya-mpilo. Ama-athomu amathathu ahlanganiswe ku-molecule yawo. Nakuba i-ozone ingadingeki ekuphefumuleni, indima yayo ayinakuphikiswa. Wonke umuntu uye wezwa ngongqimba lwe-ozone, oluvikela umhlaba emisebeni ye-ultraviolet. I-ozone nayo iyi-antioxidant. Isibonelo, amafutha omnqumo abhekwa njengenzuzo kakhulu empilweni.
Umoya-mpilo usetshenziswa kwezokwelapha
Amasilinda omoya-mpilo akuyona ukuphela kwendlela yokuyisebenzisa. Umkhuba omusha obizwa ngokuthi i-hyperbaric oxygen therapy usetshenziselwa ukwelapha imigraines, amanxeba nezinye izimo.
Umoya-mpilo udinga ukugcwaliswa
Lapho uphefumula, umzimba udonsa umoya-mpilo futhi ukhiphe isikhutha. Amangqamuzana omoya-mpilo ngokwawo awaveli emkhathini womhlaba. Izitshalo zenza umsebenzi wokugcwalisa izindawo zokugcina umoya-mpilo. Bamunca i-CO2 futhi bakhulule umoya-mpilo ohlanzekile. Ngokuvamile, lobu budlelwano be-symbiotic phakathi kwezitshalo nezilwane bugcina ibhalansi ezinzile ye-O2 ne-CO2. Ngeshwa, ukugawulwa kwamahlathi nokukhishwa kwezinto zokuthutha kusongela lokhu kulinganisela.
Umoya-mpilo uzinzile kakhulu
Ama-molecule e-oksijeni ane-athomu eboshwe ngokuqinile kunamanye ama-allotropes njenge-nitrogen yamangqamuzana. Ucwaningo lubonisa ukuthi umoya-mpilo wamangqamuzana uhlala uzinzile lapho ukucindezela okuphindwe izikhathi eziyizigidi ezingu-19 kunomkhathi womhlaba.
Umoya-mpilo uyancibilika emanzini
Ngisho nalezo eziphilayo ezihlala ngaphansi kwamanzi zidinga umoya-mpilo. Ziphefumula kanjani izinhlanzi? Bamunca umoya-mpilo oncibilikisiwe emanzini. Le ndawo yomoya-mpilo yenza kube nokwenzeka ukuba kube khona izitshalo nezilwane zasemanzini.
Izibani zasenyakatho zibangelwa umoya-mpilo
Labo abaye babona lo mbono omangalisayo ezindaweni ezisenyakatho noma eningizimu ngeke bakhohlwe ubuhle bayo. Ukukhanya kwezibani zasenyakatho kuwumphumela wokushayisana kwama-electron omoya-mpilo nama-athomu e-nitrogen engxenyeni engenhla yomkhathi womhlaba.
Umoya-mpilo ungahlanza umzimba wakho
Ukuphefumula akuyona ukuphela kwendima yomoya-mpilo. Umzimba wabantu abaningi awukwazi ukumunca izakhamzimba. Khona-ke, ngosizo lwe-oxygen, ungakwazi ukuhlanza uhlelo lokugaya ukudla. I-oksijeni isetshenziselwa ukuhlanza nokukhipha ubuthi be-gastrointestinal tract, okuthuthukisa inhlalakahle jikelele.
