Igazi lihamba njani entliziyweni yakho nasemzimbeni wakho wonke? (Igazi lihamba njani entliziyweni nasemzimbeni) Masifumanise oku kanye!

Uyazi ukuba ukuze siphile, kufuneka sigcine igazi lihamba entliziyweni yethu nasemzimbeni wethu wonke. Cinga ngalo njengesihlunu esinamandla, okanye ipompo. Yiyo ethumela igazi elinomoya-mpilo emzimbeni wonke. Emva kokuphuma entliziyweni, eli gazi lihamba ngemithambo emininzi yegazi emincinci, efana neendlela ezincinci, kwaye lihamba yonke indawo ukusuka entlokweni ukuya ezinzwaneni zakho. Igazi lakho lihlala lihamba, alimi ndawo inye. Njengoko lihamba, igazi linemisebenzi emibini ephambili ekufuneka liyenze.

Kutheni le nto ukujikeleza kwegazi kubaluleke kangaka emzimbeni wethu?

Ngamafutshane, olu hambo lwegazi lubonelela ngezondlo ezifunekayo kuwo onke amalungu omzimba kunye nezicubu zomzimba wethu.

• Okokuqala kukuhambisa ioksijini kunye nezondlo kuwo onke amalungu omzimba kunye nezicubu zomzimba wakho. Oku kufana nokuzisa ukutya kunye neziselo ekhaya lakho.
• Into yesibini kukususa igesi yekhabhoni dayoksayidi kunye nezinye izinto ezingafunekiyo eziqokelelana kwezo ndawo, njengokuba kususa inkunkuma ekhayeni lakho.

Ngoko ke, xa ioksijini iphelile kwaye inkunkuma igcwele, eli gazi libuyela entliziyweni. Emva kokuba lifike entliziyweni, eli gazi kufuneka licocwe, oko kukuthi, kufuneka lizaliswe yioksijini kwakhona kwaye kususwe i-carbon dioxide. Yiyo loo nto intliziyo ithumela eli gazi emiphungeni. Kungaphakathi kwemiphunga apho eli gazi lifumana khona ioksijini entsha kwaye inkunkuma isusiwe. Eli gazi licociweyo libuyela entliziyweni. Intliziyo iyamkela ngovuyo eli gazi licocekileyo kwaye ilipompe kwakhona emzimbeni wonke.

Ukongeza ekuthwaleni ioksijini kunye nezondlo, igazi lethu linenye into ekhethekileyo. Ezo ziiseli ezilwa nezifo, sizibiza ngokuba ziiseli ezimhlophe zegazi. Ezi seli ezimhlophe zegazi zezona zikhusela imizimba yethu kwiintsholongwane. Zihamba emzimbeni wonke, zilwa naluphi na usulelo okanye abahlaseli bamanye amazwe.

Olu hambo lwegazi luyaqhubeka, qho ngomzuzwana, qho ngeyure yosuku. Intliziyo yethu kunye nemithambo yegazi zisebenza kunye ukwenza konke oku. Yiyo loo nto sibiza le nkqubo ngokuthi yinkqubo yokujikeleza kwegazi . Njengenkonzo yokuhambisa igazi ekrelekrele esebenza ngexesha elifanelekileyo, iindawo zale nkqubo yokujikeleza kwegazi zisebenza kunye ukuhambisa igazi emzimbeni wonke ngexesha elifanelekileyo.

Khawucinge nje, ukuba kukho into ebambekayo kule mithambo yegazi, umzekelo , ihlwili legazi , okanye ukuba ukuhamba kwegazi kuhamba kancinci, yonke le nkqubo inokuphazamiseka kwaye izifo ezahlukeneyo zinokwenzeka. Yiyo loo nto kubalulekile ukwazi indlela igazi elihamba ngayo entliziyweni yakho nasemzimbeni wakho wonke. Emva koko ungenza konke okusemandleni akho ukugcina le nkqubo inamandla esebenza ngaphakathi kuwe, ingabonakali kuwe, isempilweni.

Igazi lihamba njani ngaphakathi entliziyweni?

Cinga ngentliziyo yakho njengendlu enamagumbi amane. Ineendawo ezimbini kwicala lasekunene (i-atrium yasekunene kunye ne-ventricle yasekunene) kunye neendawo ezimbini kwicala lasekhohlo (i-atrium yasekhohlo kunye ne-ventricle yasekhohlo). Igazi lakho lihamba kuzo zonke iindawo ezine - kodwa hayi ngokulandelelana.

Njengokuba ufika ekhaya uvela emsebenzini onzima, igazi lakho lihamba emzimbeni wakho wonke lize libuyele entliziyweni yakho. Liqala lingene kwigumbi eliphezulu lasekunene lentliziyo yakho, i-atrium yasekunene. Emva koko lihamba ngqo ukusuka apho liye kwigumbi elisezantsi lasekunene, i-ventricle yasekunene. Kufana nokuba ufika ekhaya uvela kwigumbi lokuhlala uze uye ngqo ekhitshini uyokutya into ethile.

Igazi elivela kwi-ventricle yasekunene alinakuya ngqo kwiigumbi ezimbini ezikwicala lasekhohlo lentliziyo. Okokuqala, kufuneka liye emiphungeni ukuze likhuphe inkunkuma lize lithathe ioksijini engaphezulu. Ngoko ke igazi liyaphuma entliziyweni liye emiphungeni. Kufana nokuba ubaleka uye kwigumbi lokuhlambela, wenze imisebenzi yakho yasekhaya, uze emva koko uhlambe ngokukhawuleza.

Emva kokuphuma emiphungeni, igazi lingena kwigumbi eliphezulu kwicala lasekhohlo lentliziyo, i-atrium yasekhohlo. Ukusuka apho, lingena kwigumbi elingezantsi kwicala lasekhohlo, i-ventricle yasekhohlo. I-ventricle yasekhohlo emva koko ipompa eli gazi liye kuwo wonke umzimba. Lijikeleza umzimba lize libuyele entliziyweni. Kufana nokuthi ulale, ulale kamnandi ebusuku, uvuke kusasa uze ubuyele emsebenzini.

Zithini iiValve zeNtliziyo?

Njengokuba kukho iingcango zamagumbi endlwini, kukho iingcango zamagumbi entliziyweni yakho. Ezi ngcango zibizwa ngokuba ziivalvu zentliziyo . Zivula kwaye zivalwe ngexesha elifanelekileyo ukulawula ukuhamba kwegazi, kwaye zigcina igazi lihamba kwicala elinye kuphela. Kukho iivalvu ezine eziphambili entliziyweni yakho:

• Ivalvu yeTricuspid: Le iphakathi kwe-atrium yakho yasekunene kunye ne-ventricle yasekunene.
• Ivalvu yepulmonary: Le iphakathi kwe-ventricle yasekunene kunye nomthambo ophambili we-pulmonary othwala igazi ukuya emiphungeni.
• Ivalvu yeMitral: Le iphakathi kwe-atrium yasekhohlo kunye ne-ventricle yasekhohlo.
• Ivalvu ye-Aortic: Le iphakathi kwe-ventricle yasekhohlo kunye ne-aorta, umthambo oyintloko othwala igazi ukusuka entliziyweni ukuya emzimbeni wonke.

Ingakanani indlela igazi elihamba ngayo entliziyweni, inyathelo ngenyathelo?

Icala lasekunene nelasekhohlo lentliziyo yakho lisebenzisana ukupompa igazi emzimbeni wakho wonke. Igazi lihamba entliziyweni ngamanyathelo aliqela. Onke la manyathelo enzeka ngexesha elinye lokubetha kwentliziyo - ixesha elifutshane, malunga nomzuzwana omnye okanye emibini.

Isiganeko kwicala lasekunene

1. Igazi eliphuma emzimbeni wonke elingenaoksijini , elithwalwa yimithambo emibini emikhulu: i-vena cava ephezulu kunye ne-vena cava engaphantsiIngena kwi-atrium yakho yasekunene nge-. Le mithambo mibini ithatha igazi kwiindawo eziphezulu nezisezantsi zomzimba wakho, ngokulandelelana, ize ilifake ngqo kwi-atrium yasekunene.

2. Ivalvu yakho ye-tricuspid iyavuleka, ivumela igazi ukuba liphume kwi-atrium yasekunene liye kwi-ventricle yasekunene.

3. Xa i-ventricle yasekunene izele ligazi, iyafinyela. Ivalvu ye-tricuspid iyavalwa ize ivalvu ye-pulmonary ivuleke.

4. Igazi lihamba ngemithambo ephambili yemiphunga kunye namasebe ayo ukuya emiphungeni, apho lifumana khona ioksijini kwaye likhuphe ikharbon diokside.

Umsitho wecala lasekhohlo

1. Igazi elinomoya-mpilo omninzi elivela emiphungeni lingena kwi-atrium yakho yasekhohlo ngemithambo emikhulu ebizwa ngokuba yi-pulmonary veins . Le mithambo ipompa igazi ngqo kwi-atrium yasekhohlo.

2. Ivalvu yakho ye-mitral iyavuleka, ithumela igazi ukusuka kwi-atrium yasekhohlo ukuya kwi-ventricle yasekhohlo.

3. Xa i-ventricle yasekhohlo izele ligazi, iyafinyela. I-valve ye-mitral iyavalwa ize i-valve ye-aortic ivuleke.

4. Intliziyo yakho ipompa igazi ngevalvu ye-aorta ukuya kwi-aorta , apho liphuma khona liye emzimbeni wonke.

Intliziyo yakho ipompa igazi elingakanani?

Ubusazi na ukuba intliziyo yakho impompa malunga neelitha ezingama-2,000 zegazi ngosuku? Oko kwanele ukuzalisa ichibi lokudada elingangeenyawo ezi-8 ubude, nelibanzi ngeenyawo ezi-10.

Kwakhona, intliziyo ibetha izihlandlo ezimalunga ne-100,000 ngosuku. Ngokomyinge, kwiminyaka engama-79 yobomi, intliziyo yakho iya kubetha izihlandlo ezimalunga ne-2.9 yeebhiliyoni! Ayimangalisi loo nto?

Ziziphi izifo ezichaphazela ukuhamba kwegazi entliziyweni?

Ezinye iimeko zonyango zinokuchaphazela ukuhamba kwegazi entliziyweni yakho. Nazi ezinye zeemeko:

• I-Arrhythmia: Ukubetha kwentliziyo okungahambelaniyo. Umzekelo , i-atrial fibrillation okanye i-ventricular fibrillation .
• Ukusilela kwentliziyo exineneyo: Ukonakala okanye ubuthathaka bemisipha yentliziyo kwenza kube nzima ngentliziyo ukupompa igazi liye kuwo wonke umzimba.
• Isifo seMithambo yeCoronary (CAD): Imithambo yegazi ethwala igazi iye kwimisipha yentliziyo iyaqina kwaye inciphe ngenxa yokwakheka kweplaque.
• Isifo seMithambo yePeripheral (PAD): Imithambo yegazi ethwala igazi kwezinye iindawo zomzimba iyaqina kwaye inciphe ngenxa yamafutha amaninzi.
• Uhlaselo lwentliziyo: Ukuvaleka ngequbuliso komthambo wentliziyo, okubangela ukulahleka komoya-mpilo kwinxalenye yemisipha yentliziyo.
• Isifo seValve yentliziyo: Imeko apho ivalve yentliziyo ingasebenzi kakuhle. Umzekelo, isenokuncipha okanye ivuza.
• Iziphene zentliziyo ezizalwa nazo: Iingxaki ngesakhiwo sentliziyo esikhoyo ekuzalweni. Umzekelo , iBicuspid Aortic Valve Disease .
• Ukubanjwa Kwentliziyo Ngequbuliso: Ukulahlekelwa ngumsebenzi wentliziyo ngequbuliso ngenxa yokungasebenzi kakuhle kwenkqubo yombane yentliziyo.

Indlela yokufumana igazi lihambahamba emzimbeni wonke, inyathelo ngenyathelo?

Intliziyo yakho ipompa igazi elineoksijini ngevalvu ye-aorta iye kwi-aorta . I-aorta ngumthambo oyintloko emzimbeni wakho. Ifana nesiqu somthi omkhulu. Amasebe amaninzi aphuma kule aorta, aye kwiindawo ezahlukeneyo zomzimba wakho nakwizitho ezahlukeneyo.

Nantsi into eyenzekayo emva kokuba igazi lingene kwi-aorta:

1. Igazi liphuma kwi-aorta liye kweminye imithambo yegazi (amasebe e-aorta) ephuma ngqo kwi-aorta.

2. Amasebe okuqala avela kwi-aorta yimithambo yentliziyo . La ngamasebe anika izihlunu zentliziyo igazi.

3. Njengoko i-aorta idlula esifubeni nasesiswini, eminye imithambo emininzi iyaphuma kuyo.

4. Ekugqibeleni, i-aorta ijika ibe yi-Y kufutshane neqhosha lesisu sakho ize yahlulwe ibe ngamasebe amabini okugqibela abizwa ngokuba yi-iliac arteries .

5. Amasebe e-aorta akhupha amasebe amancinci, njengamasebe omthi. Le mithambo iya kuzo zonke iikona zomzimba.

6. Igazi liphuma kwimithambo yegazi liye kwimithambo yegazi emincinci ebizwa ngokuba yi-arterioles .

7. Ezi arterioles zidibana nemithambo yegazi emincinci ebizwa ngokuba zii-capillaries . Iindonga zee-capillaries zincinci kakhulu, zivumela ioksijini kunye nezondlo ukuba zidlule egazini ziye kwizitho zomzimba kunye nezicubu.

8. Emva kokuhambisa ioksijini kunye nezondlo kunye nokususa inkunkuma, ii-capillaries ziqhagamshela kwimithambo yegazi emincinci ebizwa ngokuba zii-venule .

9. IiVenule zidibana nemithambo . Le mithambo ithwala igazi elisele lingenawo umoya-mpilo, eligcwele inkunkuma, libuyele entliziyweni.

10. Igazi eliphuma kuyo yonke imithambo emzimbeni ekugqibeleni lidibanisa imithambo emibini emikhulu ebizwa ngokuba yi-vena cava ephezulu kunye ne-vena cava engaphantsi .

11. Le mithambo mibini mikhulu ithwala igazi ngqo kwi-atrium yasekunene yentliziyo. Emva koko igazi libuyela entliziyweni nasemiphungeni, lize liqale ukujikeleza emzimbeni wonke.

Le nkqubo yegazi ejikeleza emzimbeni wakho yinkqubo entsonkothileyo nemangalisayo. Isebenza iiyure ezingama-24 ngosuku, nokuba uvukile okanye ulele. Oku kuhamba kwegazi rhoqo kuko okukuvumela ukuba ucinge, uthethe, ujikeleze, kwaye usebenzisane nendawo okuyo.

Zeziphi izifo ezichaphazela ukujikeleza kwegazi emzimbeni?

Izifo ezahlukeneyo zenkqubo yokujikeleza kwegazi zinokuphazamisa ukuhamba kwegazi okuqhelekileyo emzimbeni wonke. Umzekelo, unokufumana oku kulandelayo:

• Iindawo ezibuthathaka kwiindonga zemithambo yegazi (ii-Aneurysms) .
• Amafutha afakwa ngaphakathi kwimithambo yegazi(I-atherosclerosis).
• Ukuba buthathaka okanye ukonakala kwemithambo yegazi (isifo semithambo yegazi) .
• Unxibelelwano olungaqhelekanga phakathi kwemithambo yegazi kunye nemithambo yegazi (i-Arteriovenous fistulae) .

Ngamanye amaxesha, ungazithintela ezi meko ukuba zingabikho, okanye ubuncinane unciphise umngcipheko wakho. Kodwa ngamanye amaxesha, xa izinto ezifana nemfuza (oko kukuthi, ii-genes ozizuze kubazali bakho) kunye nokwaluphala zidlala indima, kusenokungabikho nto ingako sinokuyenza ngaloo nto.

Nangona kunjalo, nangona kungengazo zonke izifo ezichaphazela ukujikeleza kwegazi ezinokuthintelwa, ungathetha nogqirha kwaye ulawule naziphi na iingxaki ezivelayo, kwaye uzithintele ekubeni zibe mandundu.

Ndingenza ntoni ukuze intliziyo nomzimba wam zihlale zijikeleza kakuhle?

Nazi ezinye izinto onokuzenza ukuze ugcine ukuhamba kwegazi kusempilweni:

• Gcina ubunzima obusempilweni obukufaneleyo.
• Yitya ukutya okunempilo nentliziyo. Oko kuthetha ukutya ukutya okunamafutha aphantsi, ityuwa, neswekile, kunye neziqhamo nemifuno eninzi.
• Zilolonge malunga nemizuzu eli-150 ngeveki. Oko kuthetha malunga nemizuzu engama-30 ngosuku, iintsuku ezintlanu ngeveki.
• Nciphisa ukusetyenziswa kotywala.
• Lawula uxinzelelo. Sebenzisa iindlela ezisempilweni ezifana nonyango lokuthetha okanye ukucamngca.
• Ukuba utshaya okanye usebenzisa ezinye iimveliso zecuba, yeka.

Khawuthelekelele umbono ophuma ngefestile njengoko ulungiselela ukufika kwinqwelo-moya kufutshane nesixeko esikhulu. Uthungelwano lweendlela ezidibanayo nezingafaniyo, uthungelwano lweendlela ezinkulu... iimoto ezikwimigca emide, zihamba enye emva kwenye, zonke zizama ukuya kwindawo eziya kuyo. Kukho into exakekileyo nexakeke njengaleyo eyenzekayo emzimbeni wakho ngalo lonke ixesha, kodwa ngomlinganiselo omncinci kakhulu - njengoko igazi lihamba entliziyweni yakho nakwimithambo yegazi.

Okokugqibela, umyalezo oya ekhaya:

Ezi zinto zincinci ezenzekayo emizimbeni yethu zincinci kangangokuba asiziboni yonke imihla, ngoko ke sinokuzilibala lula. Kodwa oku kuhamba kwegazi rhoqo yikona okusigcina siphila imihla ngemihla. Akufuneki wazi zonke iinkcukacha malunga nendlela esebenza ngayo yonke into. Kodwa ukwazi izinto ezimbalwa ezisisiseko kunokukunceda uthethe nogqirha malunga nazo naziphi na iingxaki onokuba nazo, okanye malunga neendlela zokuhlala usempilweni.
