Inhliziyo iyimisipha emangalisayo eyenza ihlasele amawaka angama-100 000 ngosuku. Yimpompo eyinkimbinkimbi ekwazi ukulungelelanisa uxinzelelo lwegazi, ukuhamba kunye nomthamo ukuze unikeze umzimba wakho nayo yonke igazi eliyifunayo. Intliziyo yakho ihlala iguqulela oko uyenzayo kunye nomzimba womzimba wakho. Njengoko uneminyaka ubudala, intliziyo yakho ishintsha kwiimfuno zomzimba omdala.
Ezi zihlengahlengiso ziza kunye nokurhweba, ukushiya intliziyo ibe yingozi kakhulu kwizifo kunye nezinye iingxaki.
Yentliziyo Yakho
Nsuku zonke intliziyo yakho kufuneka ibethe ngaphezu kwama-100,000 amaxesha ukupompa iigulane ezingama-1 800 zegazi ngeekhilomitha ezili-60,000 (xa isetyenziswe ukuphela-ekupheleni) kwemithambo yegazi. Intliziyo yakho nayo kufuneka ilungele izinga kunye nokunyanzelisa apho iphephampe ngokusekelwe kwinqanaba lomsebenzi wakho. Njengoko sikhula, utshintsho emzimbeni lufuna ukuba intliziyo iguqule indlela isebenza ngayo. Ngokomzekelo, i-fatdup yamathambo e-arteries, eyaziwa ngokuba yi- atherosclerosis , ibangela ukuba intliziyo isebenze nzima ukupompa onke loo gazi nge-tubes esincinci.
Intliziyo eguga
Isifo senhliziyo sisisusa esibangela ukufa. Njengoko sikhula, intliziyo yethu ihlawulela imirhoxo ekhutshwe ngokusebenza nzima kwaye iphakamisa uxinzelelo lwegazi. Ezi zinguqu zibeka intliziyo engozini kwaye ifuthe umgangatho wobomi:
- Iipesenti ezingama-40 zokufa kwabantu abaneminyaka engama-65 ukuya kuma-74 basuka kwisifo senhliziyo (ama-60 ekhulwini kulabo abangaphezu kwama-80).
- Ukususela kwiminyaka engama-20 ukuya kuma-80, kukho ukuhla kweepesenti ezingama-50 emandleni omzimba wokuzivocavoca ngamandla
- Kwi-20s yakho, izinga eliphezulu lentliziyo liphakathi kwama-180 no-200 beats ngomzuzu. Ku-80, ngu 145.
- Intliziyo eneminyaka engama-20 ubudala inokuvelisa izihlandlo ezi-3.5 ukuya kwezi-4 i-heart's resting capacity. Umntwana oneminyaka engama-80 unokuvelisa izihlandlo ezi-2 zokuphumla amandla.
Iimitha zokuguga
Iimitha zegazi zithatha i-oxygen-rich blood away from heart and deliver it to the body. Njengoko sikhula, iimithambo zethu ziba nzima kwaye ziguquguquke. Oku kubangela ukuba uxinzelelo lwegazi lukhule. Intliziyo kufuneka ilungelelanise nokwanda kwexinzelelo lwegazi ngokukhupha ngamandla nokutshintsha ixesha lokuvala iigraves. Ezi zihlengahlengiso zishiya intliziyo ekhuselekileyo. Ukuze uhlale usemncinci ngentliziyo , khusela imirhobho yakho ngu:
- Ukusebenzisa
- Ukulawula uxinzelelo lwegazi
- Ukujonga i-cholesterol yakho
Ukunyiswa kwe-Ventricle yasekhohlo
Abaphandi baye baqaphela ukuba udonga lwe-ventricle yekhohlo yentliziyo luba lukhuni kakhulu. Oku kwandisa kukuvumela intliziyo ukuba iphephe ngamandla. Njengoko iimitha zethu zegazi ziphela, ziba ngumxinzelelo obangela ingcinezelo yegazi. Intliziyo ihlawulela oku ngokunyaniseka nokuphanga ngamandla.
I-Mitral Valve Ivala Kancinane
I-mitral valve ivala ngokukhawuleza ngokuguga. Oku kungenxa yokuba izinga lokuphuma kwegazi ukusuka kwiphepha le-ventricle lekhohlo linciphisa njengoko libuyisela ngokuthe ngcembe ngakumbi. Iphinda ihlawule ngokuthe ngcembe ngenxa yokuba ikhula kakhulu kunomdala (jonga ngasentla).
Ukuzivocavoca amandla
Njengokuba intliziyo ikhula, ayikwazi ukuphendula ngokukhawuleza kwimilayezo yeekhemikhali evela kwingqondo. Abaphandi abazi kakuhle ukuba kungani intliziyo engaphenduliyo ngokukhawuleza kwimilayezo ukukhawuleza nokulungelelanisa umsebenzi owandisiweyo.
Isiphumo ngumzimba ongeke usebenze ixesha elide okanye ngokukhawuleza njengoko ngaphambili. Oku kubonakalisa nje ukuphefumla okufutshane - uphawu lokuba igazi elityebileyo le-oxygen alihambeli ngokwaneleyo ngomzimba ngenxa yokuba imiphunga izama ukuphefumula oksijini.
"Ukuhlala" Ixabiso lentengo yeeNhliziyo
Umlinganiselo wentliziyo yomntu omdala ngelixa uhleli ehamba kancane kunomntu osemncinci (kodwa unjalo xa elele). Kucingelwa ukuba le nqanaba elincinci lisuka ekuhlaleni kwentliziyo-ukuthetha ngobuchopho kuba izicubu ezinamafutha kunye namafutha edibeneyo akhiwe kwiimiti ezidibanisa intliziyo nengqondo. Ukuhlawulela, intliziyo ikwandisa umthamo wegazi ngokusasazwa ngokunyusa uxinzelelo lwegazi lwe- diastolic .
Intliziyo ayikwazi ukuyifaka ngokukhawuleza
Ngenxa yokwanda kwe-diastolic yegazi, intliziyo iphinda ilula kakhulu intsimbi nganye, inika umpompo oqinileyo ukwenzela ukuba ube neqhinga elinamandla lokupompa umthamo wegazi ogqithiseleyo (obizwa ngokuba yi-Frank-Starling mechanism). Kodwa ngenxa yengcinezelo enkulu ye-diastolic, intliziyo ayikwazi ukuyifaka ngokukhawuleza.
Intliziyo ikhulisa
Intliziyo yempilo eneminyaka engama-70 ubudala ineepesenti ezingama-30 ezincinci kwiiseli kunentliziyo eneminyaka engama-20. Xa iiseli zeentliziyo ziyafa, ezinye iiseli kufuneka zolule kwaye zikhule zihlale zixhunyiwe. Iintsholongwane zentliziyo yabantu abadala ziba ngama-40 ekhulwini kunomntu omncinci.
Gcina Intliziyo Yakho Iphilile kwaye iguqulele iNtsholongwane Yengqondo
Intliziyo yakho inempilo nje njengemibhobho yakho. Sebenza kanzima ukugcina imiraro yakho iphilile ngo:
- Ukulawula uxinzelelo lwegazi
- Ukuphucula i- cholesterol yakho
- Ukusebenzisa
- Ukuphumla
- Ukufunda ukutya okunentliziyo
