Igazi ligeleza kanjani enhliziyweni yakho nasemzimbeni wakho wonke? (Igazi Ligeleza Enhliziyweni Nasemzimbeni) Ake sithole lokhu ngqo!

Uyazi ukuthi ukuze siphile, sidinga ukugcina igazi lihamba enhliziyweni yethu nasemzimbeni wethu wonke. Cabanga ngakho njengomsipha onamandla, noma kunalokho iphampu. Yilokho okuthumela igazi elinomoya-mpilo emzimbeni wonke. Ngemva kokuphuma enhliziyweni, leli gazi lihamba ngemithambo yegazi eminingi emincane, efana nemigwaqo emincane, futhi lihamba yonke indawo kusukela ekhanda lakho kuya ezinzwaneni zakho. Igazi lakho lihlala lihamba, alimi ndawo eyodwa. Njengoba lihamba, igazi linemisebenzi emibili eyinhloko okufanele liyenze.

Kungani lokhu kujikeleza kwegazi kubaluleke kangaka emzimbeni wethu?

Kalula nje, lokhu kugeleza kwegazi yikho okunikeza izakhamzimba ezidingwa yizo zonke izitho nezicubu emzimbeni wethu.

• Okokuqala ukuletha umoya-mpilo kanye nezakhamzimba kuzo zonke izitho zomzimba wakho. Lokhu kufana nokuletha ukudla neziphuzo ekhaya lakho.
• Into yesibili ukususa igesi ye-carbon dioxide kanye neminye imfucuza eqongelela kulezo zindawo, njengokususa udoti ekhaya lakho.

Ngakho-ke, uma umoya-mpilo usuphelile futhi imfucuza igcwele, leli gazi libuyela enhliziyweni. Ngemva kokuba lifike enhliziyweni, leli gazi lidinga ukuhlanzwa, okungukuthi, lidinga ukugcwaliswa umoya-mpilo futhi bese kususwa i-carbon dioxide. Yingakho inhliziyo ithumela leli gazi emaphashini. Kungaphakathi emaphashini lapho leli gazi lithola khona umoya-mpilo omusha bese imfucuza isuswa. Leli gazi elihlanziwe libuyela enhliziyweni. Inhliziyo iyalamukela ngenjabulo leli gazi elihlanzekile bese ilipompa futhi emzimbeni wonke.

Ngaphezu kokuthwala umoya-mpilo nezakhamzimba, igazi lethu linenye into ekhethekile. Lawo ngamaseli alwa nezifo, siwabiza ngokuthi amaseli amhlophe egazi. Lawa maseli amhlophe egazi yiwo avikela imizimba yethu kumagciwane. Ahamba emzimbeni wonke, elwa nanoma yikuphi ukutheleleka noma abahlaseli bakwamanye amazwe.

Lokhu kugeleza kwegazi kuyaqhubeka, njalo ngomzuzwana, njalo ngehora losuku. Izinhliziyo zethu nemithambo yegazi zisebenza ndawonye ukwenza konke lokhu. Yingakho sibiza lolu hlelo ngokuthi uhlelo lokujikeleza kwegazi . Njengesevisi yokulethwa ehlakaniphile esebenza ngesikhathi esifanele, izingxenye zalolu hlelo lokujikeleza kwegazi zisebenza ndawonye ukuhambisa igazi emzimbeni wonke ngesikhathi esifanele.

Cabanga nje, uma kukhona okubhajwa kule mithambo yegazi, isibonelo , ihlule legazi , noma uma ukugeleza kwegazi kuhamba kancane, lonke lolu hlelo lungaphazamiseka futhi kuvele izifo ezahlukahlukene. Yingakho kubalulekile ukwazi ukuthi igazi ligeleza kanjani enhliziyweni yakho nasemzimbeni wakho wonke. Khona-ke ungenza konke okusemandleni akho ukugcina lolu hlelo olunamandla olusebenza ngaphakathi kuwe, lungabonakali kuwe, luphilile.

Igazi ligeleza kanjani ngaphakathi enhliziyweni?

Cabanga ngenhliziyo yakho njengendlu enamakamelo amane. Inezindawo ezimbili ohlangothini lwesokudla (i-atrium yesokudla kanye ne-ventricle yesokudla) kanye namakamelo amabili ohlangothini lwesobunxele (i-atrium yesokudla kanye ne-ventricle yesokudla). Igazi lakho ligeleza kuzo zonke izindawo ezine - kodwa hhayi ngokulandelana.

Njengoba nje ufika ekhaya uvela osukwini olunzima emsebenzini, igazi lakho lihamba emzimbeni wakho wonke bese libuyela enhliziyweni yakho. Liqala lingene ekamelweni eliphezulu kwesokudla senhliziyo yakho, i-atrium efanele. Bese lisuka lapho liqonde ngqo ekamelweni eliphansi kwesokudla, i-ventricle efanele. Kufana nalapho ufika ekhaya uvela egumbini lokuphumula bese uya ngqo ekhishini ukuyodla okuthile.

Igazi elivela e-ventricle yesokudla alikwazi ukuya ngqo emakamelweni amabili ohlangothini lwesobunxele lwenhliziyo. Okokuqala, kufanele liye emaphashini ukuze lisuse ukungcola futhi lithathe umoya-mpilo owengeziwe. Ngakho igazi liyaphuma enhliziyweni liye emaphashini. Kufana nokuthi ugijimela endlini yokugezela, wenze imisebenzi yakho yasekhaya, bese ugeza ngokushesha.

Ngemva kokuphuma emaphashini, igazi lingena ekamelweni eliphezulu ohlangothini lwesobunxele lwenhliziyo, i-atrium yesobunxele. Ukusuka lapho, ligeleza liye ekamelweni elingezansi ohlangothini lwesobunxele, i-ventricle yesobunxele. I-ventricle yesobunxele bese ipompa leli gazi liye kuwo wonke umzimba. Lihambahamba emzimbeni bese libuyela enhliziyweni. Kufana nokuthi uya embhedeni, ulale kahle ebusuku, uvuke ekuseni ngakusasa bese ubuyela emsebenzini.

Ayini Ama-Heart Valve?

Njengoba nje kuneminyango yamakamelo endlini, kuneminyango yamakamelo enhliziyweni yakho. Le minyango ibizwa ngokuthi ama-valve enhliziyo . Iyavuleka futhi ivale ngesikhathi esifanele ukulawula ukugeleza kwegazi, futhi igcina igazi ligeleza ohlangothini olulodwa kuphela. Kunema-valve amane ayinhloko enhliziyweni yakho:

• I-valve ye-Tricuspid: Lokhu kutholakala phakathi kwe-atrium yakho yangakwesokudla kanye ne-ventricle yangakwesokudla.
• Ivalvu yamaphaphu: Lokhu kutholakala phakathi kwe-ventricle yangakwesokudla nomthambo omkhulu wamaphaphu othwala igazi emaphashini.
• I-valve ye-Mitral: Lokhu kutholakala phakathi kwe-atrium yesobunxele kanye ne-ventricle yesobunxele.
• I-valve ye-aortic: Lokhu kutholakala phakathi kwe-ventricle yesobunxele ne-aorta, umthambo oyinhloko othwala igazi lisuka enhliziyweni liye emzimbeni wonke.

Iyiphi indlela igazi eligeleza ngayo enhliziyweni, isinyathelo ngesinyathelo?

Izinhlangothi zesokudla nesobunxele zenhliziyo yakho zisebenza ndawonye ukupompa igazi emzimbeni wakho wonke. Igazi ligeleza enhliziyweni ngezinyathelo eziningana. Zonke lezi zinyathelo zenzeka ngesikhathi esisodwa sokushaya kwenhliziyo - isikhathi esifushane, cishe umzuzwana owodwa noma emibili.

Umcimbi ohlangothini lwesokudla

1. Igazi elingenawo umoya-mpilo emzimbeni wonke, elithwalwa yimithambo emibili emikhulu: i-vena cava ephezulu kanye ne-vena cava ephansiIngena ku-atrium yakho yangakwesokudla nge-. Le mithambo emibili ithatha igazi ezingxenyeni ezingaphezulu nezingezansi zomzimba wakho, ngokulandelana, bese ilifaka ngqo ku-atrium yangakwesokudla.

2. I-valve yakho ye-tricuspid iyavuleka, ivumela igazi ukuthi ligeleze lisuka ku-atrium yangakwesokudla liye ku-ventricle yangakwesokudla.

3. Uma i-ventricle yesokudla igcwele igazi, iyafinyela. I-valve ye-tricuspid iyavalwa bese i-valve yamaphaphu ivuleka.

4. Igazi ligeleza ngemithambo emikhulu yamaphaphu kanye namagatsha ayo liye emaphashini, lapho lithola khona umoya-mpilo bese likhipha i-carbon dioxide.

Umcimbi ohlangothini lwesobunxele

1. Igazi elinomoya-mpilo elivela emaphashini lingena e-atrium yakho yangakwesobunxele ngemithambo emikhulu ebizwa ngokuthi imithambo yamaphaphu . Le mithambo ipompa igazi ngqo e-atrium yangakwesobunxele.

2. I-valve yakho ye-mitral iyavuleka, ithumela igazi lisuka ku-atrium yangakwesobunxele liye ku-ventricle yangakwesobunxele.

3. Uma i-ventricle yesobunxele igcwele igazi, iyafinyela. I-valve ye-mitral iyavalwa bese i-valve ye-aortic ivuleka.

4. Inhliziyo yakho ipompa igazi nge-aortic valve liye kwi -aorta , lapho ligeleza khona liye emzimbeni wonke.

Inhliziyo yakho iphampa igazi elingakanani?

Ubuwazi ukuthi inhliziyo yakho ipompa amalitha angaba ngu-2,000 egazi ngosuku? Lokho kwanele ukugcwalisa ichibi lokubhukuda elingamamitha angu-1.8 ubude, elingamamitha angu-1.8 ububanzi.

Futhi, inhliziyo ishaya izikhathi ezingaba yi-100,000 ngosuku. Ngokwesilinganiso, esikhathini sokuphila seminyaka engaba ngu-79, inhliziyo yakho izoshaya izikhathi ezingaba yizigidigidi ezingu-2.9! Akumangalisi lokho?

Yiziphi izifo ezithinta ukuhamba kwegazi enhliziyweni?

Ezinye izimo zezokwelapha zingathinta ukugeleza kwegazi enhliziyweni yakho. Nazi ezinye zezimo:

• I-Arrhythmia: Ukushaya kwenhliziyo okungajwayelekile. Isibonelo , i-atrial fibrillation noma i-ventricular fibrillation .
• Ukwehluleka Kwenhliziyo Okubangelwa Ukucindezeleka: Ukulimala noma ubuthakathaka bemisipha yenhliziyo kwenza kube nzima ngenhliziyo ukupompa igazi liye emzimbeni wonke.
• Isifo Semithambo Yenhliziyo (CAD): Imithambo yegazi ethwala igazi iye emisipheni yenhliziyo iyaqina futhi inciphe ngenxa yokunqwabelana kwama-plaque.
• Isifo Semithambo Yegazi Ehambayo (i-PAD): Imithambo yegazi ethwala igazi iye kwezinye izingxenye zomzimba iyaqina futhi inciphe ngenxa yokugcwala kwamafutha.
• Ukuhlaselwa Yinhliziyo: Ukuvaleka okungazelelwe komthambo wenhliziyo, okuholela ekulahlekelweni komoya-mpilo engxenyeni yemisipha yenhliziyo.
• Isifo Se-Heart Valve: Isimo lapho i-heart valve ingasebenzi kahle. Isibonelo, ingase inciphe noma ivuza.
• Ukukhubazeka Kwenhliziyo Okubangelwa Ukwakheka: Izinkinga ngesakhiwo senhliziyo esikhona lapho kuzalwa. Isibonelo , Isifo Se-Bicuspid Aortic Valve .
• Ukuma Kwenhliziyo Okungazelelwe: Ukulahlekelwa ukusebenza kwenhliziyo ngokuzumayo ngenxa yokungasebenzi kahle kwesistimu kagesi yenhliziyo.

Indlela yokuthola igazi ligeleza emzimbeni wonke, isinyathelo ngesinyathelo?

Inhliziyo yakho ipompa igazi elinomoya-mpilo nge-valve ye-aorta liye ku-aorta . I-aorta iwumthambo oyinhloko emzimbeni wakho. Ifana nesiqu esiyinhloko somuthi omkhulu. Amagatsha amaningi ahluma kule-aorta, aye ezingxenyeni ezahlukene zomzimba wakho nasezithweni ezahlukene zomzimba.

Nakhu okwenzekayo ngemva kokungena kwegazi ku-aorta:

1. Igazi ligeleza lisuka ku-aorta liye kweminye imithambo yegazi (amagatsha e-aorta) aqhamuka ngqo ku-aorta.

2. Amagatsha okuqala avela ku-aorta yimithambo yenhliziyo . Lawa yiwo ahlinzeka ngegazi emsipheni wenhliziyo.

3. Njengoba i-aorta idlula esifubeni nasesiswini, eminye imithambo eminingi iphuma kuyo.

4. Ekugcineni, i-aorta iphenduka ngesimo sika-Y eduze kwenkinobho yesisu sakho bese ihlukana ibe amagatsha amabili okugcina abizwa ngokuthi imithambo ye-iliac .

5. Amagatsha e-aorta akhipha amagatsha amancane, njengamagatsha esihlahla. Le mithambo iya kuwo wonke amagumbi omzimba.

6. Igazi ligeleza lisuka emithanjeni liye emithanjeni yegazi emincane kakhulu ebizwa ngokuthi ama-arterioles .

7. Lawa ma-arterioles axhuma emithanjeni yegazi emincane kakhulu ebizwa ngokuthi ama-capillary . Izindonga zama-capillary zincane kakhulu, zivumela umoya-mpilo nezakhamzimba ukuthi zidlule zisuka egazini ziye ezithweni nasezicutshini.

8. Ngemva kokuletha umoya-mpilo nezakhamzimba nokususa imfucuza, ama-capillary axhuma emithanjeni yegazi emincane ebizwa ngokuthi ama-venule .

9. Ama-Venule axhuma emithanjeni . Le mithambo ithwala igazi eligcwele ukungcola, elingasenawo umoya-mpilo manje, libuyele enhliziyweni.

10. Igazi elivela kuyo yonke imithambo emzimbeni ekugcineni lihlangana nemithambo emibili emikhulu ebizwa ngokuthi i-vena cava ephezulu kanye ne-vena cava engaphansi .

11. Le mithambo emibili emikhulu ithwala igazi ngqo liye e-atrium efanele yenhliziyo. Igazi bese lidlula emuva enhliziyweni nasemaphashini, bese liqala ukujikeleza emzimbeni wonke.

Lolu hlelo lwegazi olujikeleza emzimbeni wakho luyisimiso esiyinkimbinkimbi kakhulu nesimangalisayo. Lusebenza amahora angama-24 ngosuku, kungakhathaliseki ukuthi uvukile noma ulele. Lokhu kugeleza kwegazi okuqhubekayo yikona okukuvumela ukuthi ucabange, ukhulume, uzulazule, futhi uxhumane nendawo okuyo.

Yiziphi izifo ezithinta ukujikeleza kwegazi emzimbeni?

Izifo ezahlukahlukene zesimiso sokujikeleza kwegazi zingaphazamisa ukuhamba kwegazi okuvamile emzimbeni wonke. Isibonelo, ungase ubhekane nalokhu:

• Izindawo ezibuthakathaka ezindongeni zemithambo yegazi (ama-Aneurysms) .
• Ukuqongelela kwamafutha ngaphakathi kwemithambo yegazi(I-atherosclerosis).
• Ubuthakathaka noma ukulimala kwemithambo yegazi (isifo semithambo yegazi) .
• Ukuxhumana okungajwayelekile phakathi kwemithambo yegazi nemithambo yegazi (i-Arteriovenous fistulae) .

Ngezinye izikhathi, ungavimbela lezi zimo ukuthi zingenzeki, noma okungenani unciphise ingozi yakho. Kodwa ngezinye izikhathi, lapho izici ezifana nofuzo (okungukuthi, izakhi zofuzo ozizuza kubazali bakho) nokuguga kudlala indima, kungase kungabi kuningi esingakwenza ngakho.

Nokho, nakuba kungezona zonke izifo ezithinta ukujikeleza kwegazi ezingavinjelwa, ungakhuluma nodokotela futhi uphathe noma yiziphi izinkinga ezivelayo, futhi uzivimbele ukuthi zingabi zimbi kakhulu.

Yini engingayenza ukuze inhliziyo nomzimba wami kuhlale kugeleza kahle?

Nazi ezinye izinto ongazenza ukuze ugcine ukugeleza kwegazi okunempilo:

• Gcina isisindo esinempilo esikufanele.
• Yidla ukudla okunempilo kwenhliziyo. Lokho kusho ukudla ukudla okunamafutha amancane, usawoti, noshukela, kanye nezithelo nemifino eminingi.
• Zivocavoce cishe imizuzu eyi-150 ngesonto. Lokho cishe imizuzu engama-30 ngosuku, izinsuku ezinhlanu ngesonto.
• Nciphisa ukusetshenziswa kotshwala.
• Lawula ukucindezeleka. Sebenzisa izindlela ezinempilo njengokwelapha ngenkulumo noma ukuzindla.
• Uma ubhema noma usebenzisa eminye imikhiqizo kagwayi, yeka.

Cabanga ngombono ongaphandle kwefasitela njengoba ulungiselela ukufika endizeni eduze kwedolobha elikhulu. Inethiwekhi yemigwaqo exhumanisa futhi ehlukanayo, inethiwekhi yemigwaqo emikhulu... izimoto ezisemigqeni emide, zigeleza ngokulandelana, zonke zizama ukufika lapho ziya khona. Kukhona into ematasa futhi ematasa efanayo eyenzekayo emzimbeni wakho ngaso sonke isikhathi, kodwa ngezinga elincane kakhulu - njengoba igazi lihamba enhliziyweni yakho nasemithanjeni yegazi.

Ekugcineni, umyalezo okufanele uwuthathe uye ekhaya:

Lezi zinto ezincane ezenzeka emizimbeni yethu zincane kakhulu kangangokuthi asiziboni nsuku zonke, ngakho-ke singazikhohlwa kalula. Kodwa lokhu kugeleza kwegazi okuqhubekayo yikho okusigcina siphila usuku nosuku. Akudingeki wazi yonke imininingwane mayelana nokuthi konke kusebenza kanjani. Kodwa ukwazi izinto ezimbalwa eziyisisekelo kungakusiza ukuthi ukhulume nodokotela nganoma yiziphi izinkinga ongase ube nazo, noma mayelana nezindlela zokuhlala uphilile. Uma unemibuzo mayelana nokugeleza kwegazi lakho, noma yini enye empilweni yakho, noma uma unokungabaza, ungalokothi unqikaze ukubuza udokotela. Impilo yakho iyinto ebaluleke kakhulu onayo!

Inhliziyo , ukugeleza kwegazi, ukujikeleza kwegazi, umoya-mpilo, isifo senhliziyo, impilo, imithambo yegazi
