Indlu encane enamandla emzimbeni wethu - Konke mayelana nenhliziyo!

Sawubona! Unjani? Namuhla sizokhuluma ngesitho esimangalisayo nesibaluleke kakhulu emzimbeni wethu. Leso yinhliziyo yethu. Cabanga nje, bekuzokwenzekani uma le gajethi encane ingayeka! Ngakho-ke namuhla sizokhuluma ngalomngane obalulekile empilweni yethu obizwa ngokuthi inhliziyo ngemininingwane emincane. Njengokukhuluma nomngane wakho omkhulu, kalula.

Iyini inhliziyo? Ikuphi?

Kalula nje, inhliziyo iyiphampu yemisipha enamandla kakhulu epompa igazi emizimbeni yethu yonke. Yiyo ethwala umoya-mpilo nezakhamzimba kuwo wonke amaseli emzimbeni wethu, futhi ithwala nemikhiqizo engcolile.

Ikhaya lenhliziyo - yiba ngakwesokunxele kwesifuba

Inhliziyo yakho iphakathi kwesifuba sakho, phakathi kwamaphaphu akho, ithambekele kancane ngakwesobunxele. Ivikelwe yizimbambo, njengenqaba. Uzizwa uphaphathekile kancane uma ubeka isandla sakho esifubeni sakho? Yilapho lo mshini omangalisayo usebenza khona.

Ubukhulu bezinhliziyo zethu, ezincane kodwa ezenza izinto ezinkulu

Cabanga nje, inhliziyo yakho icishe ilingane nenqindi yakho. Akumangalisi yini? Lo sayizi omncane uphampa amalitha angaba ngu-7000 egazi ngosuku! Lokho kusho ukuthi ushaya cishe izikhathi ezingu-70-80 ngomzuzu. Yilokhu esikubiza ngokuthi ukushaya kwenhliziyo .

Yini engaphakathi kwenhliziyo? Kufana nendlu!

Empeleni kunezindawo ezine ngaphakathi kwenhliziyo. Lezi sizibiza ngokuthi i-atria nama-ventricle. Zibuye zisikwe njengeminyango esiza ukugeleza kwegazi ohlangothini olulodwa kuphela.

Amakamelo amane - i-Atria ne-Ventricles

Amakamelo amabili amancane phezulu kwenhliziyo abizwa ngokuthi i-atria . I-atrium yesokudla ithola igazi elisetshenzisiwe lomzimba elingenawo umoya-mpilo. I-atrium yesokudla ithola igazi elihlanzekile elinomoya-mpilo elivela emaphashini. Amakamelo amabili amakhulu, aqinile phansi abizwa ngokuthi ama-ventricle . I-ventricle yesokudla ipompa igazi elingenawo umoya-mpilo liye emaphashini ukuze lithathe umoya-mpilo. I-ventricle yesokudla iyingxenye enamandla kakhulu yenhliziyo. Ngoba ipompa igazi eline-oxygen liye kuwo wonke umzimba. Cabanga, kusukela ekhanda lakho kuya ezinzwaneni zakho!

Iminyango evuleka ngendlela eyodwa kuphela - Amavalvu

Phakathi kwala makamelo enhliziyo naphakathi kwemithambo emikhulu ethwala igazi emakamelweni kukhona ama-valve amane. Lawa afana neminyango evula indlela eyodwa kuphela. Umsebenzi wala ma-valve ukuvumela igazi ukuthi ligeleze ohlangothini olulodwa kuphela. Avimbela igazi ukuthi ligeleze libuyele emuva. Isifo senhliziyo se-valve senzeka lapho la ma-valve engasebenzi kahle.

Imithambo Emikhulu Yegazi - Imithambo yegazi emikhulu ethwala igazi iye futhi isuke enhliziyweni

Kunezinhlobo ezimbili zemithambo yegazi emikhulu exhunywe enhliziyweni.

• Imithambo : Lena yimithambo ethwala igazi elingenawo umoya-mpilo (eyaziwa nangokuthi "igazi elingcolile") lisuka emzimbeni liye enhliziyweni. Imithambo emikhulu kakhulu yiSuperior Vena Cava kanye ne-Inferior Vena Cava .
• Imithambo : Lena yimithambo ethwala igazi elinomoya-mpilo (eyaziwa nangokuthi "igazi elihlanzekile") lisuka enhliziyweni liye emzimbeni. Umthambo omkhulu kunayo yonke yi -Aorta . Umthambo othwala igazi emaphashini ubizwa ngokuthi i-Pulmonary Artery .

Imisipha yenhliziyo - i-Myocardium

Inhliziyo iyisitho esakhiwe ngemisipha ekhethekile. Lokhu kubizwa ngokuthi i-myocardium . Yilokhu okunikeza inhliziyo amandla ewadingayo ukushaya nokupompa igazi. Inhliziyo nayo idinga igazi ukuze isebenze. Lelo gazi linikezwa yimithambo yenhliziyo . Uma le mithambo ivalekile , kuba nokuhlaselwa yinhliziyo (i-Myocardial Infarction) .

Lo mshini omncane usebenza kanjani ? Kuyamangalisa!

Indlela inhliziyo esebenza ngayo iyinkimbinkimbi kakhulu, kodwa futhi iyamangalisa kakhulu. Ifana nephampu enkulu esebenza ngokungayeki.

Njengomshini wokupompa igazi

Uhlangothi lwesokudla lwenhliziyo luqoqa igazi elisetshenziswa ngumzimba bese lilithumela emaphashini ukuze lithole umoya-mpilo. Igazi elibuya emaphashini lithatha umoya-mpilo bese libuyela ohlangothini lwesobunxele lwenhliziyo, lapho liphampulwa khona emzimbeni wonke. Lo mjikelezo uyaqhubeka. Cabanga nje, lo msebenzi uyaqhubeka ngisho nalapho silele!

Uhlelo lukagesi lwenhliziyo - indlela olulawula ngayo ukushaya kwenhliziyo (i-SA node, i-AV node)

Inhliziyo ayishayi nje kuphela. Inesistimu kagesi ekhethekile. Inhloko yalokhu yi -node ye-sinoatrial (i-node ye-SA) . Leli yiqoqo elincane lamaseli atholakala phezulu kwe-atrium kwesokudla. Yilapho kuqala khona isignali kagesi inhliziyo edinga ukuyishaya. Kufana ne -pacemaker yemvelo yenhliziyo yethu. Lesi signali siya endaweni ebizwa ngokuthi i-atrioventricular node (i-AV node) . Ukusuka lapho, isignali siya kumaseli futhi siwenze aqine. Uma kukhona okungahambi kahle ngalolu hlelo lukagesi, ukushaya kwenhliziyo kuba okungajwayelekile. Sikubiza lokho ngokuthi i-arrhythmia .

Kuyini Ukushaya Kwenhliziyo Nomfutho Wegazi?

Isilinganiso senhliziyo yinani lezikhathi inhliziyo yakho eshaya ngazo ngomzuzu. Kumuntu omdala onempilo, lokhu kuphakathi kokushaya okungu-60 no-100 ngomzuzu uma uphumule. Kuyanda uma uzivocavoca noma wesaba. Umfutho wegazi yingcindezi igazi eliyikhiphayo ezindongeni zemithambo yakho yegazi. Ilinganiswa ngezinombolo ezimbili (isb. 120/80 mmHg). Inombolo ephezulu, ``umfutho we-Systolic``, yingcindezi lapho inhliziyo ifinyela futhi ipompa igazi. Inombolo engezansi, ``umfutho we-Diastolic``, yingcindezi lapho inhliziyo iphumula futhi igcwele igazi. Ukuba nomfutho wegazi ophezulu (umfutho wegazi ophakeme) njalo akukuhle enhliziyweni.

Singazigcina kanjani izinhliziyo zethu ziphilile? Qiniseka ukuthi uyazenza lezi zinto!

Inhliziyo yethu yinto okudingeka siyinakekele kahle, ngoba kuphela uma iphilile lapho singaba nempilo futhi sijabule khona.

• Masiqaphele ukuthi sidlani futhi siphuzani:
• Yidla okwengeziwe: izithelo, imifino, imifino eluhlaza, okusanhlamvu okuphelele (irayisi elinsundu, i-oatmeal), inhlanzi (ikakhulukazi izinhlanzi ezinamafutha njenge-salmon ne-herring).
• Yehlisa: Usawoti, ushukela, ukudla okunamafutha, izinongo zokwenziwa , ukudla okunamafutha ashintshiwe (ngezinye izikhathi kutholakala ezitsheni ezibhakiwe, ama-noodle asheshayo).
• Phuza amanzi amaningi.
• Ukuzivocavoca umzimba kungumngani omkhulu wenhliziyo:
• Yenza uhlobo oluthile lokuzivocavoca olukwenza ujuluke, okungenani izinsuku ezi-5 ngesonto, okungenani imizuzu engama-30 ngosuku. Ukuhamba, ukugijima, ukugibela ibhayisikili, ukudansa, ukubhukuda, noma yini ilungile.
• Ukuzivocavoca kuqinisa inhliziyo, kulawula umfutho wegazi , futhi kwandisa amazinga e-cholesterol enhle ( i-HDL Cholesterol).
• Masigweme ukubhema notshwala:
• Ukubhema kuyisitha esikhulu senhliziyo. Kungavimba imithambo yegazi, kwandise umfutho wegazi, futhi kwandise nengozi yokuhlaselwa yinhliziyo.
• Ukuphuza utshwala ngokweqile nakho kuyingozi enhliziyweni.
• Masinciphise ukucindezeleka:
• Ukucindezeleka njalo akukuhle enhliziyweni. Izinto ezifana nokuzindla, i-yoga, ukuzibandakanya nomsebenzi wokuzilibazisa, kanye nokukhuluma nabangani kungasiza ekunciphiseni ukucindezeleka.
• Ukuhlolwa njalo kwezokwelapha kubalulekile:
• Ngemva kweminyaka engu-30-40, kubaluleke kakhulu ukuhlola umfutho wegazi lakho, amazinga kashukela egazini, kanye namazinga e-cholesterol okungenani kanye ngonyaka. Ngaleyo ndlela, uma kukhona inkinga, ungayibona ngokushesha.
• Qaphela futhi lezi zifo:
• Uma unezimo ezifana nomfutho wegazi ophakeme , isifo sikashukela , noma i-cholesterol ephezulu , landela imiyalelo kadokotela wakho ngokucophelela. Ukuzilawula kubaluleke kakhulu ukuvikela inhliziyo yakho.

Khumbula, inhliziyo yakho isezandleni zakho! Izinguquko ezincane zingenza umehluko omkhulu.

Ezinye izinkinga ezifika enhliziyweni - masiqaphele

Ngisho noma unakekelwa kahle, izinkinga zenhliziyo zingavela ngezinye izikhathi. Ukuqaphela lokhu kungakusiza ukuthi ufune ukwelashwa ngokushesha uma kuvela izimpawu.

Kuyini ukuhlaselwa yinhliziyo (i-Myocardial Infarction)? Ziyini izimpawu?

Ukuhlaselwa yinhliziyo (i-myocardial infarction) kwenzeka lapho umthambo wenhliziyo ohlinzeka ngegazi emisipheni yenhliziyo uvaleka ngokuzumayo, okubangela umonakalo kuleyo ngxenye yenhliziyo. Lesi yisimo esiphuthumayo!

• Izimpawu eziyinhloko:
• Umuzwa wokucindezela, ukucindezela, noma ukuqina maphakathi nesifuba. Lobuhlungu bungadlulela engalweni yesobunxele, entanyeni, emhlathini, noma emhlane.
• Ubunzima bokuphefumula.
• Ukujuluka.
• Isicanucanu, ukuhlanza.
• Isiyezi (vertigo), ukuquleka.

Okubalulekile: Uma uhlangabezana nesinye noma ngaphezulu salezi zimpawu, ungachithi isikhathi uye esibhedlela ngokushesha!

Ukwehluleka Kwenhliziyo Ngamagama Alula

Ukwehluleka Kwenhliziyo yisimo lapho inhliziyo ingakwazi ukupompa igazi elanele emzimbeni. Lokhu akwenzeki ngokuzumayo, kodwa kwenzeka lapho inhliziyo iba buthakathaka ngokuhamba kwesikhathi.

• Izimpawu zingafaka:
• Ubunzima bokuphefumula (ikakhulukazi uma uzivocavoca noma ugoba).
• Ukuvuvukala kwemilenze namaqakala.
• Ukucasuka, ukukhathala.
• Ukushaya kwenhliziyo okusheshayo noma okungajwayelekile.

Ukushaya kwenhliziyo okungajwayelekile - i-Arrhythmia

I-Arrhythmia iwukushaya kwenhliziyo okungajwayelekile. Kungasho ukuthi inhliziyo ishaya kancane, ngokushesha, noma ngokungajwayelekile. Nakuba amanye ama-arrhythmia engeyona ingozi, amanye angaba yingozi. Isibonelo i- atrial fibrillation .

• Izimpawu zingafaka:
• Ukushaya kwenhliziyo.
• Isiyezi (vertigo).
• Ukuphelelwa umoya.
• Ubuhlungu besifuba.

Izinkinga ze-valve (Isifo Senhliziyo se-Valvular)

Uma ama-valve enhliziyweni engasebenzi kahle, kungakhathaliseki ukuthi awavuli kahle (stenosis) noma awavali kahle (regurgitation), ukugeleza kwegazi kuyavimbeka. Lokhu kuthinta nenhliziyo.

Uma uzizwa kanje, thintana nodokotela ngokushesha!

Uma unezinye zezimpawu ezishiwo ngenhla, ungakuzibi. Bonana nodokotela ngokushesha. Ukuxilongwa kusenesikhathi kanye nokwelashwa kungavimbela umonakalo omkhulu.

Okokugcina, into ebaluleke kakhulu (Umyalezo Wokuya Ekhaya)
