Mhlawumbi ukhe wazibona ezo veins ziluhlaza okwesibhakabhaka phantsi kolusu lwethu, ingakumbi ezingalweni nasemilenzeni yethu, akunjalo? Sonke sizibiza ngokuba "yimithambo," kodwa ziyintoni ngokwenene? Ngaba wakha wazibuza ukuba yintoni umsebenzi obalulekileyo wale veins emzimbeni wethu? Yiloo nto siza kuthetha ngayo kweli nqaku namhlanje, ngokulula nangendlela enobuhlobo. Makhe sijonge le veins, oko kukuthi, yonke into malunga nemithambo.
Zithini imithambo nje?
Ngamafutshane, imithambo yegazi luhlobo lomthambo wegazi ohamba emizimbeni yethu. Ifana nenethiwekhi yeendlela ezithwala impahla ejikeleze imizimba yethu. Umsebenzi wazo ophambili kukubuyisela igazi elingenaoksijini entliziyweni emva kokuba lisetyenziswe kwiindawo ezahlukeneyo zomzimba.
Khawucinge nje, malunga ne-75% yomthamo wegazi opheleleyo emzimbeni wethu ukwimithambo yegazi nangaliphi na ixesha. Oko kuthetha ukuba imithambo yegazi yinxalenye ebaluleke kakhulu kwinkqubo yethu yokujikeleza kwegazi.
Yintoni umahluko omkhulu phakathi kwemithambo yegazi kunye nemithambo yegazi?
Usenokuba ukhe weva ngemithambo yegazi. Nangona zombini ezi zithwala igazi, kukho umahluko omkhulu phakathi kwazo zombini.
- Imithambo yegazi: Le ithwala igazi elineoksijini eninzi ukusuka entliziyweni ukuya kuzo zonke iindawo zomzimba, njengemibhobho ethwala amanzi acocekileyo esuka kwitanki yamanzi ukuya kuzo zonke iindawo zendlu.
- Imithambo: Le iqokelela igazi elingenaoksijini emzimbeni wonke ize ilibuyisele entliziyweni. Ifana kakhulu nenkqubo yemibhobho eqokelela kwaye ikhuphe amanzi angcolileyo ekhayeni lakho.
Kodwa kukho imeko enye ekhethekileyo yoku. Le yimithambo yemiphunga . Le ihambisa igazi elineoksijini eninzi ukusuka emaphashini ukuya entliziyweni. Le yindawo kuphela apho umthambo uthwala igazi elineoksijini eninzi.
Indlela emangalisayo igazi elihamba ngayo emizimbeni yethu
Oku kufana nokuba neendlela ezimbini zeebhasi ezijikeleza isixeko. Makhe sibone ukuba oku kusebenza njani.
1. Isekethe Yokuqala (Isekethe Yenkqubo): Okokuqala, igazi elinomoya-mpilo omninzi elithathwe emiphungeni laza laziswa entliziyweni liphonswa yintliziyo lize lithunyelwe emzimbeni wonke ngemithambo yegazi. Eli gazi liya kuzo zonke iiseli kunye nezicubu zomzimba, lizinika ioksijini kunye nezondlo ezizidingayo.
2. Uhambo lokubuya: Nje ukuba ioksijini ifike, inkunkuma evela kwiiseli, ingakumbi i-carbon dioxide, yongezwa egazini. Eli gazi ngoku liba ligazi elingenaoksijini .
