Ividiyo

Okulotshiweyo

Ngaphakathi nangaphandle, ngaphakathi nangaphandle.

Ukuhlala uphila kumayelana nokwenza izinto. Lo mzuzwana nje , amangqamuzana akho ashisa ama-molecule eglucose anomoya-mpilo

ukwenza amandla atholakale, okugcina uphila ngomunye umzuzu oyigugu.

Ukuyisa i-oxygen kumaseli akho uyaphefumula.

Ukuphefumula kuyimpendulo yenkinga enzima kakhulu: Uzithola kanjani izinsiza ezidingeka kumaseli akho ukuze ziphile,

kusukela ngaphandle, ziye ngaphakathi kwamaseli akho? Yonke into ephilayo kufanele ixazulule le nkinga

futhi isixazululo sehluke ngokumangazayo ngokuya ngesinye sezilawuli ezibaluleke kakhulu zempilo:

Usayizi.

Njengoba sike saxoxa kwamanye amavidiyo:

Ngezilinganiso ezahlukahlukene, imithetho yemvelo yendawo yonke inemiphumela ehlukile kubahlali bayo.

Izinto ezilula njengokushisa, i-microgravity noma ukungezwani komhlaba kungenzeka kungabi ndaba zalutho kuwe noma kube yingozi ebulalayo

• kuya ngokuthi umkhulu kangakanani.

Izinto eziphilayo zidinga izinto eziningi ezahlukahlukene ukuzigcina ziqhubeka.

Futhi ngandlela thile badinga ukuzihambisa zisuka ngaphandle ziye ngaphakathi.

Lokhu bekuyinkinga enkulu ezintweni zokuqala eziseceleni kokuphila, ngoba ukwenza noma yini endaweni yethu yonke kudinga amandla.

Futhi izidalwa zokuqala emhlabeni zazingenawo amathuluzi namasu amaningi atholakalayo

impilo ekhona namuhla emva kwezigidigidi zeminyaka yokuziphendukela kwemvelo.

Ngakho-ke ekuqaleni, impilo yayidinga ukuthola indlela yokuthola izinto ezinhle ngaphakathi

nezimbi ngaphandle kwazo ngaphandle kokusebenzisa amandla.

Ngenhlanhla, izinhlobo zokuqala zokuphila zazincane kakhulu.

Futhi ngoba bebancane kakhulu, bakwazile ukusebenzisa indlela yokuhamba yamahhala

ebisuselwa kumthetho womzimba obizwa nge-diffusion.

Ukwehliswa kungukubusa kwendawo yonke ukuthi ama-molecule, ikakhulukazi oketshezi noma amagesi,

ahlala ezungeza nxazonke.

Futhi ngenxa yokuthi ziyahamba zishayisana zize zishayisane nezinye nezinye izinhlayiya, zivame ukusakazeka.

Isibonelo, uma uphonsa ikhiyubhu kashukela emanzini lapho-ke kukhona ushukela omningi endaweni eyodwa

futhi kwenye indawo awukho.

Njengoba ama-molecule kashukela encibilika emanzini azoqala ngokungahleleki aqubisane nama-molecule wamanzi,

namanye ama-molecule kashukela.

Kancane kancane onke ama-molecule kashukela azosabalala futhi akhe izigaba eziningi zokugxila okuhlukile.

Lokhu kuhamba okungahleliwe kuyaqhubeka ngokungapheli, kuze kube yilapho ushukela uzobe usakazeka

ngokulinganayo emanzini.

Into enhle ngokusabalala ukuthi impilo ingakusebenzisa mahhala, ayidingi mandla.

Futhi impilo ithanda izinto zamahhala. Ngakho-ke yonke impilo emhlabeni incike ekusakazekeni.

Ake sibheke isidalwa esincane kunazo zonke emhlabeni, igciwane. Ngokuqondile izindawo zayo.

Ulwelwesi lweseli luvumela ukusakazeka kwama-molecule athile.

Leli bhaktheriya elithile lisebenzisa i-oxygen ukuze liphile, kuyilapho i-carbon dioxide ikhiqizwa ngaphakathi,

njengomkhiqizo odoti.

Ngakho-ke ngaphakathi kwegciwane alinawo umoya-mpilo omningi, kepha kunesikhutha esiningi.

Ngenxa yokwanda kwalezi zinhlayiya ekugcineni zizosabalala ngokulinganayo, ngakho-ke isikhutha ziyaphuma,

kuyilapho umoya-mpilo ugcwaliswa njalo ngaphandle.

Kepha lolu hlobo “lokuphefumula” lusebenzela umhlaba omncane kakhulu.

Kumagciwane, i-amoeba noma amaseli akho kanye nezilwane ezimbalwa ezincane kakhulu.

Izinambuzane ngokwesibonelo zinenethiwekhi enhle ye-trachea, imigudu ene-gradient yengcindezi,

lapho umoya uhamba kancane ungangena futhi ushintshe amagesi namaseli ezinambuzane.

Kepha ngisho nezinambuzane zibonakala zikwazi ukuthola i-trachea yazo

futhi okungenani ezinye zinezitho zokuphefumula ezikhethekile njengezindonga namasaka omoya.

Esikalini esithile ukusakazeka kuhamba kancane kakhulu ukugcina amaseli ephila.

Inkinga eyisisekelo ukuthi ukushintshaniswa nemvelo kungenzeka kuphela ngaphezulu

futhi ukusabalala kwezinto kungasekela inani elithile langaphakathi kuphela.

Izinto eziphilayo ezincane zinokuncane ngaphakathi kuphela, noma ivolumu nokuningi ngaphandle,

noma indawo engaphezulu.

Kepha kuthiwani uma besifuna ukudala ibacteriuma elingana nomkhomo oluhlaza okwesibhakabhaka

futhi sibe nomshini wokukhulisa olula kakhulu?

Singadabukisa ngokudabukisayo ngomthetho wesikwele osikwele.

Kafushane nje kusho ukuthi uma wenza okuthile kube kukhulu ngokuphindwe kayishumi,

ingaphandle layo, noma ingaphezulu, lingakhula ngo-100 kodwa ingaphakathi lalo, noma ivolumu ikhula izikhathi eziyi-1000.

Uma siqhathanisa ibhaktheriya i-Pseudomonas aeruginosa nomkhomo oluhlaza okwesibhakabhaka,

siyabona ukuthi ibhaktheriya linobuso obuphindwe izikhathi eziyizi-10 000 000 maqondana nomthamo walo kunewhale.

Ibhaktheriya inezinto eziningi ezingaphandle, kuyilapho umkhomo unezingaphakathi eziningi.

Uma senza ibhaktheriya elingana nomkhomo - amabhaktheriya ethu amakhulu manje anezingaphakathi

eziningi kakhulu futhi ingxenye yalo engaphakathi manje ikude kakhulu nobuso bayo.

Umoya-mpilo odingwa yibhaktheriya lethu ubungeke ufinyelele ngaphakathi ngaphambi kokuba uphelelwe umoya-mpilo.

Igciwane lethu elikhulu lingavele life. Noma kunjalo, ukuba mkhulu kuneziphambeko eziningi.

Ukusuka ekubeni nzima ukudliwa nokwenza kube lula ukudla abanye.

Kepha usayizi wamaseli unqunyelwe ibanga i-oksijeni nezakhamzimba ezingasabalalisa ngempumelelo

ukunikeza ngaphakathi izinsiza ezanele.

Ngakho-ke impilo igweme le nkinga ngokwakha izakhiwo ezinamaseli amaningi -

Izidalwa ezakhiwe ngamaseli amaningi esikhundleni sowodwa.

Ngoba ukusakazeka kusebenza kangcono uma unamayunithi amaningi amancane kunenye eyodwa enkulu kakhulu.

Ngokuhamba kwesikhathi abangani beseli baqala ukuhlanganyela umsebenzi futhi bagxila.

Amanye amaseli agxile ekuzweleni imvelo, amanye ekugayeni, amanye ekunyakazeni.

Kepha lokho kwakunganele.

Inkinga yokwanda nokukhiqizwa komhlaba namandla isalile,

kunciphisa ubukhulu lezi zinhlobo zokuqala zokuphila ezingafinyelela.

Ngakho-ke ukuze ikhule kakhulu -

impilo ixazulule inkinga yokusakazeka ngokuba nezimbobo nemihume nemihubhe nangokuzisonga ngokwayo,

ngakho-ke ukusakazeka kungenzeka kalula kuseli ngalinye.

Zithathele: Okucabangayo ngaphandle, isikhumba sakho, kunendawo engaba amamitha-skwele ama-2.

Kodwa amaphaphu akho anobuso obungamamitha-skwele angaba ngu-70.

Awafani namabhaluni, afana neziponji ezigcwaliswe ngamabhaluni amaningi aqoqwe ngokuqinile,

azungezwe yimithambo yegazi.

Uma uphefumula, wonke la mabhaluni amancane agcwala umoya ohlanzekile.

Igazi eligcwele i-CO2 limpompwa lizungeze amabhaluni.

Futhi-ke umlingo wokusabalalisa uyenzeka.

Umoya-mpilo uya egazini lapho uthathwa khona ngamaseli abomvu egazi.

Futhi i-CO2 isakazeka iphume egazini iye emaphashini akho, lapho ingaphefumulelwa khona futhi.

Igazi lakho bese lithwala igazi elicebile lomoya-mpilo liye emakhoneni akude kakhulu omzimba wakho

bese licosha udoti we-CO2.

Ukwehla emzimbeni kusebenza cishe ku-millimeter eyodwa,

ngakho-ke wonke amaseli emzimbeni wakho okungenani abe milimitha elilodwa ukusuka esitsheni segazi.

Ngakho-ke izilwane eziphakathi nendawo ezifana nawe zidinga imithambo yegazi eminingi ukufinyelela wonke amaseli emzimbeni.

Umzimba wakho unamakhilomitha angama-100,000 ama-capillaries wodwa,

imithambo yegazi yakho emincane kunayo yonke, enendawo engaphezulu kwamamitha-skwele ayi-1000.

Lokhu kuyiqiniso kuzo zonke izingxenye zakho ezifuna ukushintshana ngokuthile nezwe langaphandle.

Umzimba wakho udinga indawo ukuze uthathe izakhamzimba ekudleni kwakho,

ngakho-ke isisu sakho sinendawo engaphezulu kwesigamu senkundla ye-badminton, cishe amamitha-skwele angama-40.

Uma ukhudlwana, izindawo ozifihla kakhulu ozidingayo.

Thatha umuthi. Indlela yayo yokuhlala iphila ukudala ushukela ngaphandle komoya omncane nokukhanya kwelanga.

Ngakho-ke idinga indawo engaphezulu ngangokunokwenzeka.

Isihlahla esiwolintshi esinamaqabunga ayizinkulungwane ezimbili sinendawo engaphezulu kweqabunga engamamitha-skwele angama-200.

Kepha indawo engaphakathi kwamaqabunga lapho kwenzeka khona ukusabalala empeleni ingamamitha-skwele ayi-6000.

Kuyafana nangezimpande, lapho amanzi ehlukana khona nomhlabathi abe yizinwele eziningi ezingenakubalwa

ezikhulisa indawo engaphezulu.

Izimpande zemitha eyisikwele yotshani zifaka cishe amamitha-skwele angama-350 wobuso!

Uma sibheka ukwehluka okumangalisayo kokuphila kule planethi kubukeka sengathi konke kuhluke kakhulu.

Futhi kunjalo.

Kodwa ezinye izimiso eziyisisekelo ziyefana kuwo wonke umuntu futhi azikashintshi ngokuphawulekayo izigidigidi zeminyaka,

uma sibheka okuncane kakhulu noma okukhulu kakhulu:

Imfucuza iyaphuma bese kungena uphethiloli omusha. Izilwane ezinkulu zidinga nje okunzima kakhulu amapayipi ukwenza kwenzeke.

Uphethiloli omusha yinto esingayisebenzisa sonke ngezikhathi ezithile, ikakhulukazi kubuciko bethu.

Konke okudingeka ngempela ukuzama okuthile okusha futhi sinethuba elihle lokukuqalisa :

Sisebenzisane ne-Skillshare, umphakathi wokufunda online onikeza izifundo cishe kunoma yiliphi ikhono lobuciko,

njenge-Design, Illustration, Animation, Photography nokupheka.
