Emzimbeni wethu udlulela ngaphezu kwe-90,000 km yemitha yegazi ehamba malunga ne-4.5-5.5 ilitha yegazi.
Isiseko se-neuralgic sale nkqubo enhle yintliziyo-isisigxina esisisigxina esiqhubela igazi rhoqo nge-oxygen. Le yindlela ebalulekileyo kakhulu, kuba isondlo seeseli zonke kuxhomekeke ekusebenzeni kwayo ukusebenza.
Ngokukhawuleza ukunikezelwa kweeseli ezinezondlo, igazi libuyela entliziyweni, lingena kwiimvumba ezingezantsi kunye ezingezantsi. Emva koko, emva kokuzaliswa komoya okhanya, igazi liyaqhubeka lihamba kulo lonke umzimba.
Iinkalo ezinomdla malunga nokujikeleza kwegazi
- Ukuhamba kwegazi entliziyweni kuthatha imizuzwana emine.
- Ukujikeleza kwegazi kumaphepha angaphantsi kuthatha imizuzwana engama-18, kunye nengqondo - malunga nemizuzwana engama-8.
- Iingqungquthela ezi-3,000 zolu lwaluko zivela rhoqo.
- Ubude beemithanjeni zethu zegazi li ngaphezu kwama-90,000 km. Oku kuthetha ukuba banokubanjelwa emhlabeni ngokuphindwe kabini.
- Ubuninzi benkqubo ye-capillary yi-2500 capillaries nganye nge-square millimeter yeethambo.
Iimitha - iimpahla ezinoxanduva lobomi bamaselula
Ukufumana iiseli zazo zonke izondlo eziyimfuneko kuxhomekeke ngokupheleleyo kumjikelezo wegazi oqhelekileyo. Kwaye imida ejongene nokuhanjiswa kwezi zondlo. Kwimeko apho ukubonelelwa kwezondlo kuqala ukungasebenzi, iiseli zivaphazeleka, ziphoqelelwe ukuzimela ngokuzimela indlela yokuphuma kwiimeko ezingalindelekanga. Ekuqaleni banokuqhubeka nokuqhuba umsebenzi wabo, nangona kungenasiphelo sokuhamba kwegazi. Kodwa ke, lo ngumda. Ngokuqhelekileyo imiraro yokuthuthwa kwezinto ezimbiweyo, i-enzyme, iivithamini, ushukela, amafutha kunye ne-oksijeni, oko kukuthi, izinto ezisisiseko eziyimfuneko ebalulekileyo kwimisebenzi ebalulekileyo yeeseli zomzimba wethu.
Umkhosi wokukhanga
Ininzi yexesha esiyichitha ukuma okanye ukuhlala kwaye ngokukhawuleza silele phantsi. Ngoko ke, umqobo oyintloko owanqoba imithanjeni, ukubuyisela igazi entliziyweni, ngumandla wokukhangela.
Imithambo ilula kakhulu ukwenza umsebenzi wayo, njengoko oku kuququzelelwa ukupheliswa kwentliziyo, kuyimfuneko ukuhamba kwegazi ngomzimba. Kwiimvini, ngokuchaseneyo, uxinzelelo luyancipha.
Ngako oko, ukunqoba amandla okukhanga, inkqubo ye-venous kufuneka ibe nezinye izixhobo. Ngokomzekelo, xa sigijima okanye sihamba, uxinzelelo oluqhutyelwa ngophuzu lomhlathi (inxalenye ephihliweyo yeengcambu zonyawo) kuvumela igazi ukuba liphakamise entliziyweni. Ngeli xesha, indlela yokwenza i-suture ye-venous iqala ukudlala, ngoko kubizwa ngokuba ngummandla onomnatha weethambo. Umsebenzi oyintloko esiwucacisile nje ukunika impembelelo yokuqala yegazi ukwenzela ukuba ezi zilandelayo ziphakamise entliziyweni.
Ngakolunye uhlangothi, kukho ezinye iindlela zokulahlwa kwenkqubo ye-venous eyenzelwe ukuqinisekisa ukubuyela okulungileyo kwegazi entliziyweni. Inkontileka yesikhumba se-calf ngesikhulu ngelixa isanda, iqhuba ingcinezelo kwiimvini ezithinteleyo apho zithinta khona, ngaloo ndlela zitshintshe igazi entliziyweni.
Kwinqanaba elingaphakathi kweemvini, kukho iipavini ezincinci (ezingenayo imirhobho), ezalathisa iiswini kwiintliziyo. Ekugqibeleni, ubuncinci kubalulekile umsebenzi wokuphefumula, owenza umququzelelo wokuhamba kwegazi xa isalathisi sakhula kwisisu esiswini.
Inetha elinzulu nelingenangqiqo
Isistim sezinambuzane sinomlinganiselo omkhulu weemvini ze-dimers ezahlukileyo, ezazisasazwa kuwo wonke umzimba.
Ngokubhekiselele kwinkqubo jikelele yeemida eziphantsi zomzimba wethu (imilenze), kufuneka idibene ngamanethiwekhi amabili.
- Inethiwekhi enzulu ijongene nokuthutha igazi eliye lahla iisumbu. Iimvumba zethungelwano olunzulu zizisa entliziyweni 90% yegazi.
- Inethwekhi engaphelelanga idlulisa i-10% yegazi kunye namagatsha kwiisishu zangaphantsi. Kule ntanethi, eyenziwa ngamagqabi angaphantsi kunye neengqumbo, ukuba i-varicose veins iyakhula ngokuyinhloko. Ingongoma efanelekileyo kukuba ekubeni inkqubo engabonakaliyo yenzelwe ukuthutha iindleko ezininzi zegazi, ukususwa kweemvumba ze-varicose akuyi kuba yingxaki kwinkqubo yokujikeleza.
