Imithambo yegazi Healthy: ubomi ngaphandle nesifo sentliziyo

Igazi emzimbeni isebenza njengento osuka ukuba umsebenzi ebalulekileyo iseli ngalinye yelungu ngalinye. intshukumo wayo emzimbeni kuthiwa ukujikeleza, apho ioksijini, iihomoni kunye nezondlo anikwe onke ancedisana amalungu, yaye ukusuka apho ngoncedo iimveliso imveliso yokubola izinto inkunkuma. Ukongeza, igazi uphumeza thermoregulation emzimbeni, kwaye ukwakhusela ukusuka kwi iintsholongwane eziyingozi. Ukuqhubeka zibonelela imithambo yegazi yegazi kunye nentliziyo ezenza inkqubo yokujikeleza kwegazi, bonke abenza imisebenzi nelisebenza ngokungqongqo.

imithambo yegazi, jikelele kabani ubude kuhlanganisiwe 100 amawaka. Km, lihlaba umzimba womntu njenge web omkhulu, evumela yonke iseli nomoya. Blood flow kwenzeka ngqo nge kwemithambo, imithambo yegazi kunye emithanjeni.

Umthambo - a izitya zamafu wayifu- ukuba unikezele ukuhamba kwegazi avela entliziyweni. Bona nezimo kakhulu kwaye, kuxhomekeke umthamo wegazi ezimpontshelwa lwentliziyo ukwandisa okanye isivumelwano. Kwemithambo ethumela igazi ahlanganiswe mpilo arhogelwe, oko kukuthi "uhlambulukile". Vienna, ngokuchaseneyo, ukuvelisa lokuphuma igazi ezaliswe carbon dioxide. Ngokutsho kuye igazi lisondela intliziyo. Emthanjeni iindonga ubukhulu ngaphantsi yegazi. Emithanjeni zikhona iimpahla yegazi lincinci iludonga obhityileyo kakhulu ngalo ukubuya igazi iiseli oksijini kunye nezakhi kunye carbon dioxide ndima exchange lweemveliso igazi kwiseli.

Eyona inkulu (in cross-kwicandelo ifikelela 5 cm) igazi isitya emzimbeni zabantu - aorta apho amasebe zibe imithambo yegazi - kuba arterioles (iimpahla ezincinane), kunye nabo ke, xa emithanjeni.

Umfutho ukuhanjiswa igazi uVuyo. Ukuhamba kwegazi kwenzeka izangqa ezimbini: ezincinane (pulmonary) kunye lokuhamba zenkqubo, flow gqolo. Xa uqhuba kwi isangqa amancinci ugwetyelwe, wakhululwa kuso carbon dioxide kunye mpilo. Isangqa esikhulu, bathi kanye, unika athwala ioksijini kunye nezondlo, ukuthatha carbon dioxide kunye nenkunkuma iimveliso.

imithambo yegazi Human zidlala indima ebalulekileyo kwiinkqubo ezibalulekileyo zomzimba. Bona nilwamkelele ilize ebizwa ngokuba "imithambo ubomi": kuqhina kunye phantse zonke iiseli zomzimba, baya kuqinisekisa umsebenzi wayo ivumelane.

Izazinzulu zithi ukuba imithambo yegazi ukuba ukwaluphala banxibe kancinane phambi kokuba ezinye iinkqubo zomzimba. Kwaye ke abantu bembiza ibhekisela nini kwaye yintoni ukuba adle, asele, ukuba athathe inxaxheba kwezemidlalo, oko kukuthi, yintoni ubomi bakhe ngokunxaxha, i ngokukhawuleza inkunkuma eziphilayo nobumdaka ezahlukeneyo ezifakwe kwi ezindongeni imithambo yegazi. Slagging izitya ikhokelela ukugxagxiseka igazi emzimbeni, nto leyo ebangela esiqwini ukungabikho izondlo ezibalulekileyo. Ngoko ke nokuphuhlisa sonke isifo ezaziwayo, yaye ekubeni kukho ukuguga yomzimba.

isifo sentliziyo kunye seswekile kunye nomhlaza ukuza kuthi ga ngoku, ngokuqinileyo ukubamba entendeni phakathi izifo eziyingozi kakhulu kwaye zinabe. Xa iqela izifo iimpahla intliziyo igazi kulandelayo:

- isifo sentliziyo,

- isifo sentliziyo samathambo,

- ukuphazamiseka kwemithambo yobuchopho,

- naso isifo sentliziyo ,

- Embolism pulmonary,

- deep vein thrombosis,

- isifo lwemithambo peripheral.

izifo ezihlasela zosulele ezifana kwamalungu omzimba nokuhlaselwa yintliziyo zenzeka ngenxa ikakhulu occlusion isitya ethintela olunye kwegazi liya ubuchopho okanye intliziyo. Isizathu sokuba nezithintelo - iidipozithi ngamanqatha ezindongeni angaphakathi imithambo yegazi unikezele igazi intliziyo okanye ingqondo.

A ubunzima ezizodwa uzingela izifo nentliziyo semithambo na nazimpawu, uphethwe kwabo ngexesha ke ayiyi kuphela ukunceda ukukhusela ngokuchasene iingxaki ezinzulu, kodwa kwezinye iimeko - ukusindisa ubomi.
