Ake sifunde konke mayelana nomsindo wokushaya kwezimpilo zethu - inhliziyo.

Wake wabeka isandla sakho esifubeni sakho walalela lowo msindo oshayayo? Lowo msindo oqhubekayo wokukhahlela... ukukhahlela... uyingoma yokuphila kwethu. Leyo yinhliziyo yethu. Njengephampu yamanzi endlini, lesi sitho esincane sisigcina siphila ngokupompa igazi emizimbeni yethu yonke. Ngakho-ke, namuhla, ake sixoxe ngalesi sitho esimangalisayo esiyigugu kithi, inhliziyo yethu, ngemininingwane eyengeziwe , njengokungathi sikhuluma nomngane.

Iyini inhliziyo? Yini ngempela eyenzayo?

Kalula nje, inhliziyo iyisitho esinamandla kakhulu, esinemisipha esilingana nenqindi yakho. Ingumnikazi wesimiso sethu sokujikeleza kwegazi . Umsebenzi wayo oyinhloko ukupompa igazi emzimbeni wonke.

Cabanga ngakho, wonke amaseli emzimbeni wethu adinga umoya-mpilo kanye nezakhamzimba ukuze asebenze. Njengoba nje imoto idinga uphethiloli. Ngakho-ke, lo moya-mpilo kanye nezakhamzimba kuthuthwa kuye kuzo zonke izingxenye zomzimba ngegazi ngoba inhliziyo iyaphampa. Futhi, leli gazi liqoqa izinto ezingadingekile ezikhiqizwa emaseli, ikakhulukazi imikhiqizo engcolile njenge- carbon dioxide, bese liyithwala liye ezindaweni ezifanele ukuze isuswe emzimbeni.

Ngaphezu kwalowo msebenzi oyinhloko, inhliziyo yenza ezinye izinto ezimbalwa ezibalulekile:

• Ilawula ukushaya kwenhliziyo kanye nesigqi: Yilokhu okulawula inhliziyo ukuthi ishaye ngokushesha lapho silele nalapho sizivocavoca.
• Ilawula umfutho wegazi: Inhliziyo iyasiza ekugcineni umfutho wegazi usebenza ezindongeni zemithambo yegazi njengoba uhamba kuyo.

Inhliziyo ayisebenzi yodwa ukwenza lezi zinto. Uhlelo lwethu lwezinzwa kanye nohlelo lwe-endocrine , oluyisistimu ekhiqiza ama-hormone, lulawula konke lokhu ndawonye.

Yiziphi izingxenye zenhliziyo ezifana nendlu?

Indlela engcono kakhulu yokuqonda isakhiwo senhliziyo ukuyiqhathanisa nendlu enkulu. Le ndlu inezindonga, amakamelo, iminyango, amapayipi amanzi, kanye nohlelo lwezintambo zikagesi. Ake sibone ukuthi ziyini.

1. Izindonga Zenhliziyo - Njengezindonga zendlu

Izindonga zenhliziyo yimisipha efinyela (ecindezelayo) futhi ephumula (ephumulayo) ukuze ipompe igazi. Lezi zindonga zakhiwe ngezingqimba ezintathu eziyinhloko:

• I-Endocardium: Ingqimba encane yangaphakathi.
• I-Myocardium: Ungqimba oluphakathi, olujiyile nolunamandla kakhulu lwemisipha. Yenza iningi lomsebenzi wokupompa kwenhliziyo.
• I-Epicardium: Ingqimba evikelayo engaphandle.

Inhliziyo yonke izungezwe yisikhwama esivikelayo esibizwa ngokuthi i-pericardium . Uketshezi olungaphakathi kwalesi sikhwama luvimbela inhliziyo ukuthi ingashayisani nezitho ezizungezile, njengamaphaphu, uma ishaya.

2. Amakamelo Enhliziyo - Njengamakamelo amane endlu

Inhliziyo yethu inamakamelo amane amakhulu, noma amakamelo. Amakamelo amabili phezulu namakamelo amabili phansi.

3. Ama-valve enhliziyo - Njengeminyango yendlu

Kunezingxenye ezifana nomnyango emithanjeni eyinhloko ezithwala igazi phakathi kwala makamelo futhi ziphume emakamelweni. Lawa abizwa ngokuthi ama-valve. Umsebenzi wawo oyinhloko ukuvumela igazi ukuthi ligeleze ohlangothini olulodwa kuphela . Avimbela igazi ukuthi ligeleze libuyele emuva. Kunezi-valve ezine eziyinhloko.

• I-valve ye-Tricuspid: Umnyango ophakathi kwe-atrium yangakwesokudla kanye ne-ventricle yangakwesokudla.
• I-valve yamaphaphu:Umgodi lapho umthambo othwala igazi usuka e-ventricle yesokudla uya emaphashini uqala khona.
• I-valve ye-mitral: Umnyango ophakathi kwe-atrium yangakwesobunxele kanye ne-ventricle yangakwesobunxele.
• I-valve ye-aorta: Isango ekuqaleni kwe-aorta, umthambo omkhulu othwala igazi lisuka kwi-ventricle yesobunxele liye kuwo wonke umzimba.

4. Imithambo Yegazi - Njengemibhobho yamanzi endlini

Kukhona inethiwekhi yamapayipi athwala futhi abuyisele igazi lisuka enhliziyweni emzimbeni wonke. Lezi yizinhlobo ezintathu eziyinhloko.

• Imithambo yegazi: Imithambo yegazi ethwala igazi elinomoya-mpilo lisuka enhliziyweni liye emzimbeni wonke. Njengemigwaqo emikhulu.
• Imithambo: Imithambo ethwala igazi eliphelelwe umoya-mpilo lisuka ezingxenyeni zomzimba libuyele enhliziyweni.
• Ama-capillary: Imithambo yegazi emincane kakhulu, emincane. Axhumanisa imithambo yegazi nemithambo yegazi. Ukushintshana komoya-mpilo namaseli omzimba kanye nokususwa kwe-carbon dioxide kwenzeka kulezi zinhlayiya.

5. Uhlelo Lokuqhutshwa Kogesi - Njengezintambo zikagesi endlini

Inhliziyo ayishayi nje kuphela. Inesistimu yesignali kagesi. Kufana nezintambo zikagesi endlini. Kungenxa yalesi simiso ukuthi amakamelo enhliziyo afinyela ngesigqi esihlelekile nesijwayelekile.

• I-Sinoatrial (SA) node: Lena yi-generator eyinhloko yenhliziyo. Isignali kagesi ebangela ukuba inhliziyo ishaye iqala lapha.
• I-node ye-Atrioventricular (AV): Yamukela isignali evela ku-node ye-SA bese iyithumela kumaseli angezansi ngokubambezeleka okuncane. Lokhu kubambezeleka okuncane kuvumela i-atria ukuthi ifinyele ngokugcwele futhi igcwalise amaseli ngegazi.
• Lesi siginali sibe sesisabalala kuwo wonke amaseli ngokusebenzisa imicu ekhethekile (imicu yePurkinje) bese sibangela ukuba afinyele.

Izifo zenhliziyo ezivamile kanye nezimpawu

Njengoba inhliziyo iyisitho esimatasa kakhulu, kunezifo eziningi ezisithintayo. Isifo senhliziyo siyimbangela ehamba phambili yokufa eSri Lanka nasemhlabeni jikelele. Ake sibheke izimo ezivame kakhulu.

• I-Arrhythmia: Ukushaya kwenhliziyo okungajwayelekile. Kungashaya ngokushesha kakhulu, kancane kakhulu, noma kungashaya ngokungajwayelekile.
• Isifo semithambo yenhliziyo: Amafutha (i-cholesterol) afakwa emithanjeni ehambisa igazi enhliziyweni, okuyenza inciphe. Lesi yisona sizathu esiyinhloko sokuhlaselwa yinhliziyo.
• Ukuhlaselwa yinhliziyo / Ukuhlaselwa yinhliziyo: Uma umthambo wenhliziyo uvalekile ngokuphelele, ukuhlinzekwa kwegazi emisipheni yenhliziyo kuyanqamuka, okubangela ukuba imisipha yenhliziyo ife.
• Ukwehluleka kwenhliziyo okubangelwa yi-congestive:Ubuthakathaka bekhono lenhliziyo lokupompa igazi. Lokhu kwenza ingakwazi ukupompa igazi elanele emzimbeni.
• Umfutho wegazi ophakeme: Umfutho wegazi okhishwa yigazi njengoba lihamba emithanjeni yegazi uphakeme kunojwayelekile. Ngokuvamile ubizwa ngokuthi "umbulali othule" ngoba ngokuvamile awubangeli izimpawu.
• Isifo se-valve yenhliziyo: Iminyango yenhliziyo, okungukuthi, ama-valve, ayivuli noma ayivaleki kahle.

Ziyini izimpawu zalesi simo?

Uma unesinye noma ngaphezulu salezi zimpawu, kubaluleke kakhulu ukubona udokotela ngokushesha .

• Ubuhlungu besifuba, ukuqina, noma ukungakhululeki.
• Ukushaya kwenhliziyo.
• Ubunzima bokuphefumula.
• Isiyezi, umuzwa wokuzungeza.
• Ukuzizwa ukhathele kakhulu (Ukukhathala).
• Ukuvuvukala kwemilenze namaqakala.

Ungayigcina kanjani inhliziyo yakho iphilile?

Nakuba isifo senhliziyo siyisimo esibucayi, izindaba ezinhle ukuthi singayinciphisa kakhulu le ngozi ngokwenza izinguquko endleleni yokuphila.

Nazi ezinye izinto ezilula ongazenza:

• Yidla ukudla okunempilo kwenhliziyo: Yidla imifino eminingi, izithelo, ubhontshisi, kanye nokusanhlamvu okuphelele (njengelayisi elinsundu kanye ne-oats). Nciphisa ukudla kwakho uwoyela, usawoti, ushukela, kanye nokudla okucutshunguliwe.
• Zivocavoce njalo: Zibekele okungenani imizuzu eyi-150 yokuzivocavoca okunamandla aphakathi ngesonto. Izinto ezifana nokuhamba ngokushesha, ukugijima, noma ukubhukuda zilungile.
• Gcina isisindo esinempilo: Ukugcina isisindo esinempilo ngobude bakho kunciphisa izingozi ezifana nomfutho wegazi ophakeme nesifo sikashukela.
• Gwema ukubhema ngokuphelele: Ukubhema kungenye yezitha ezinkulu zenhliziyo. Uma ubhema, funa usizo lokuyeka.
• Lawula ukucindezeleka: Ukucindezeleka kubi enhliziyweni. Unganciphisa ukucindezeleka ngokwenza izinto ezifana nokuzindla, i-yoga, noma ukwenza into oyithandayo.
• Hlola umfutho wegazi lakho, i-cholesterol, kanye namazinga kashukela: Thola ukuhlolwa njalo kwezokwelapha futhi uqaphele la mazinga. Uma kudingeka, sebenzisa imithi udokotela wakho ayinikezayo ngqo.

Inhliziyo yakho iyisipho esiyigugu kunazo zonke owake wasithola. Kungumthwalo wakho ukuyinakekela kahle. Uma unenkinga ngempilo yenhliziyo yakho, ungesabi ukukhuluma nodokotela wakho.
