Ama-tubes akho amabhantshi angenye yezibhubhu lapho umoya udlula khona emaphashini akho ukuze ufike endaweni lapho oksijini engena khona egazini kanye nemikhiqizo edoti ikhishwa ukuze iphefumulelwe emzimbeni.
Ukuphefumula Kusebenza Kanjani?
Uma uphefumulela umoya, udlula emakhaleni akho noma emlonyeni, ngokusebenzisa i-larynx, nase-trachea noma nge-windpipe.
Kusukela ku-trachea yakho, umoya uhlukanisa phakathi kwezingxenyeni zakho zokunene ezihamba phambili nezikhohlo, noma i-bronchus engakwesokudla nangakwesobunxele.
Njengoba izibhubhu zakho ze-bronchial ziqhubeka zihamba futhi zincane futhi ezincane, zibizwa ngokuthi i-bronchi bese i- bronchioles . Izindlela zakho zokuhamba emoyeni ziphela ezinkampanini zomoya ezibizwa nge- alveoli , lapho ukushintshaniswa kwe-carbon dioxide ne-oksijini kwenzeka khona. Ama-alveoli azungezwe inethiwekhi yemithwalo yegazi okuthiwa i-capillaries. Ama-capillari yilapho umoya-mpilo ungena khona emzimbeni wegazi ukuze unikezwe kuwo wonke umzimba futhi umzimba ulahla imikhiqizo ethile yokudoba efana ne-carbon dioxide.
Ngemuva kokuba i-oksijini ingena ekuphumeni kwegazi kuma-capillaries, ibuyela emuva enhliziyweni lapho isakazwa kuwo wonke umzimba. Njengoba i-oksijeni inikezwa emangqamuzaneni emzimbeni itshintshaniswa ne-carbon dioxide ebuyiselwa emuva kwamapillari futhi ekugcineni iphuma emaphashini.
Izibhamu Ze-Bronchial Futhi Zivimbela Abahlaseli Basezizweni
Nakuba udokotela wakho ngokuvamile ekhuluma ngokukhiqizwa kwe-mucus e-asthma, udinga i-mucus ukuze uphile.
I-mucus yenza njenge-pad enamathelayo futhi izama ukugcina izinto zangaphandle ezingekho emapapheni akho ngaphandle. Akugcini nje ukuthi i-mucus igcina amaphaphu amanzi, kodwa isebenza njengesicupho sokugcina izinto ezinjengothuli, amabhaktheriya, noma amagciwane angabangela ukuhlaselwa yisifuba.
Izibhamu Ze-Bronchial Zithinteka Ngayo Isifo Somoya?
I-asthma ithinta ama-tubes obhubhane ngokubangela ukuvuvukala okungaholela ekukhiqizweni kwe- bronchoconstriction nokukhiqizwa kwe-mucus okwandisa ukugeleza komoya.
Ngenxa yalokho, izinguquko ziholela ezimpawu ezifana nalezi:
Izindlela zokwelapha ezitshalweni zamaconsial zomzimba zizobili izidakamizwa ukuze zinikeze ukuphumula okuphawulekayo nezidakamizwa ezenzelwe ukuvimbela izimpawu ze-asthma. I-inhalers yokukhulula iklanyelwe ukuhlinzeka ngokukhululeka kwe-asthma ngokuvula ukuhamba kwe-airways nokwandisa umoya. Lezi mithi zithathwa kuphela uma zidinga futhi zisebenzisa ngaphezulu kokuphindwe kabili ngesonto kubonisa ukulawulwa okungahambi kahle kwe-asthma. Imithi yokuvikela , ngakolunye uhlangothi, ithathwa nsuku zonke kungakhathaliseki ukuthi uzizwa kanjani. Le mithi ivimbela ukuvuvukala nokukhiqizwa kwe-mucus ukufika ekugcineni ukuze ukwandise izimpawu zakho ze-asthma,
I-asthma ngokuvamile ayilimazi ngokuphelele isakhiwo se-tubon bronchial, kodwa ezinye izifo zingakwazi, njenge:
- Izifo ezijwayelekile
- Bronchiectasis
- I-cystic fibrosis
- Izifo zokuzivikela
- Umzimba wangaphandle
Kodwa-ke, kunemiphumela yesikhathi eside ku-asthma elawulwa kabi. Nakuba izimpawu eziningi ze-asthma ziguqulwa ngemithi, ukuvuvukala okungapheli kungabangela inqubo ebizwa ngokuthi i-airway remodeling. Eminyakeni eminingi yokulawulwa kwe-asthma empofu, ukukhishwa okungapheli kwamaphaphu kungenzeka futhi ekugcineni kuholele ekukhubazekeni. Indlela kuphela yokuvimbela lokhu ukuthi ingenzeki ukuthola ukusebenza nge-asthma yakho.
