Masifunde yonke into malunga nesandi esibethayo sobomi bethu - intliziyo.

Ngaba wakha wabeka isandla sakho esifubeni sakho waza wamamela eso sandi sitshoyo? Eso sandi siqhubekayo sokukhaba... ukukhaba... sisingqisho sobomi bethu. Yintliziyo yethu leyo. Njengempompo yamanzi endlwini, esi sitho sincinci sisigcina siphila ngokupompa igazi emizimbeni yethu. Ngoko ke, namhlanje, masithethe ngesi sitho simangalisayo esixabiseke kakhulu kuthi, intliziyo yethu, ngokweenkcukacha ezithe vetshe, ngokungathi sithetha nomhlobo.

Yintoni intliziyo? Yintoni kanye kanye eyenzayo?

Ngamafutshane, intliziyo sisitho esinamandla kakhulu, esinemisipha esilingana nenqindi yakho. Yinkosi yenkqubo yethu yokujikeleza kwegazi . Umsebenzi wayo ophambili kukupompa igazi emzimbeni wonke.

Cinga ngako oku, yonke iseli emzimbeni wethu ifuna ioksijini kunye nezondlo ukuze isebenze. Njengokuba imoto ifuna ipetroli. Ngoko ke, le oksijini kunye nezondlo zithwalwa zisiwe kuzo zonke iindawo zomzimba ngegazi kuba intliziyo iyampompa. Kwakhona, eli gazi liqokelela izinto ezingafunekiyo eziveliswa kwiiseli, ngakumbi inkunkuma efana nekhabhoni diokside, kwaye izithwale ziye kwiindawo ezifanelekileyo ukuze zisuswe emzimbeni.

Ukongeza kuloo msebenzi uphambili, intliziyo yenza nezinye izinto ezibalulekileyo:

• Ilawula isantya sentliziyo kunye nesingqisho: Yiyo le nto ilawula intliziyo ukuba ibethe ngokukhawuleza xa silele naxa sizilolonga.
• Ilawula uxinzelelo lwegazi: Intliziyo inceda ukugcina uxinzelelo, okanye uxinzelelo, oluphuma egazini eludongeni lwemithambo njengoko ludlula kuyo.

Intliziyo ayisebenzi yodwa ukwenza ezi zinto. Inkqubo yethu yemithambo-luvo kunye nenkqubo ye-endocrine , eyinkqubo evelisa iihomoni, zilawula zonke ezi zinto kunye.

Zeziphi iindawo zentliziyo ezifana nendlu?

Eyona ndlela ilungileyo yokuqonda ulwakhiwo lwentliziyo kukuthelekisa nendlu enkulu. Le ndlu ineendonga, amagumbi, iingcango, imibhobho yamanzi, kunye nenkqubo yeengcingo zombane. Masibone ukuba zeziphi.

1. Iindonga Zentliziyo - Njengeendonga zendlu

Iindonga zentliziyo zimisipha ezifinyezayo (ezicinezelayo) neziphumzayo (eziphumzayo) ukuze zipompe igazi. Ezi ndonga zenziwe ngamaleya amathathu aphambili:

• I-Endocardium: Umaleko ongaphakathi obhityileyo.
• I-Myocardium: Umaleko ophakathi, otyebileyo nowomeleleyo wemisipha. Wenza uninzi lomsebenzi wokupompa kwentliziyo.
• I-Epicardium: Umaleko ongaphandle okhuselayo.

Intliziyo yonke ijikelezwe yingxowa ekhuselayo ebizwa ngokuba yi-pericardium . Ulwelo olungaphakathi kwesi sikhwama luthintela intliziyo ekungqubaneni namalungu angqongileyo, njengemiphunga, xa ibetha.

2. Amagumbi entliziyo - Njengamagumbi amane endlu

Intliziyo yethu inamagumbi amane aphambili, okanye amagumbi. Amagumbi amabini aphezulu kunye namagumbi amabini asezantsi.

3. Iivalvu zentliziyo - Njengeengcango zendlu

Kukho iindawo ezifana nomnyango kwimithambo ephambili ethwala igazi phakathi kwezi gumbi kwaye ziphuma kwiigumbi. Ezi zibizwa ngokuba ziivalvu. Umsebenzi wazo ophambili kukuvumela igazi ukuba lihambe kwicala elinye kuphela . Zithintela igazi ukuba libuye umva. Kukho iivalvu ezine eziphambili.

• Ivalvu yeTricuspid: Ucango oluphakathi kwe-atrium yasekunene kunye ne-ventricle yasekunene.
• Ivalvu yemiphunga:Umnyango apho umthambo othwala igazi ukusuka kwi-ventricle yasekunene ukuya emiphungeni uqala khona.
• Ivalvu yeMitral: Ucango oluphakathi kwe-atrium yasekhohlo kunye ne-ventricle yasekhohlo.
• Ivalvu ye-Aorta: Isango elisekuqaleni kwe-aorta, umthambo omkhulu othwala igazi ukusuka kwi-ventricle yasekhohlo ukuya emzimbeni wonke.

4. Imithambo yegazi - Njengemibhobho yamanzi endlwini

Kukho uthungelwano lweetyhubhu ezithwala kwaye zibuyisele igazi entliziyweni emzimbeni wonke. Ezi zezona ntlobo zintathu ziphambili.

• Imithambo yegazi: Imithambo yegazi ethwala igazi elineoksijini ukusuka entliziyweni ukuya emzimbeni wonke. Njengeendlela ezinkulu.
• Imithambo: Imithambo ethwala igazi eliphelelwe yioksijini lisuka kwiindawo zomzimba lisiya entliziyweni.
• IiCapillaries: Imithambo yegazi emincinci kakhulu, emincinci. Zidibanisa imithambo yegazi kunye nemithambo yegazi. Ukutshintshiselana kweoksijini kwiiseli zomzimba kunye nokususwa kwekhabhoni diokside kwenzeka kwezi capillaries.

5. Inkqubo yoQhuba umbane - Njengentambo yombane endlwini

Intliziyo ayibethi nje kuphela. Inenkqubo yesignali yombane. Ifana neentambo zombane endlwini. Kungenxa yale nkqubo ukuba amagumbi entliziyo afinyezeke ngesingqisho esicwangcisiweyo nesiqhelekileyo.

• I-Sinoatrial (SA) node: Le yeyona generator iphambili yentliziyo. Isignali yombane ebangela ukuba intliziyo ibethe iqala apha.
• I-Atrioventricular node (AV): Ifumana isignali evela kwi-SA node ize iyithumele kwiiseli ezingezantsi ngokulibaziseka okuncinci. Oku kulibaziseka okuncinci kuvumela i-atria ukuba ifinyeze ngokupheleleyo ize izalise iiseli ngegazi.
• Olu phawu lusasazeka kuzo zonke iiseli ngokusebenzisa iifayibha ezikhethekileyo (iifayibha zePurkinje) kwaye lubangele ukuba zinciphe.

Iingxaki zentliziyo eziqhelekileyo kunye neempawu

Ekubeni intliziyo ililungu elixakekileyo kakhulu, kukho izifo ezininzi eziyichaphazelayo. Isifo sentliziyo sesona sibangela sokufa eSri Lanka nakwihlabathi liphela. Makhe sijonge ezona meko zixhaphakileyo.

• I-Arrhythmia: Ukubetha kwentliziyo okungahambelaniyo. Ingabetha ngokukhawuleza kakhulu, kancinci kakhulu, okanye ingabetha ngokungahambelaniyo.
• Isifo semithambo yegazi: Amafutha (i-cholesterol) afakwa kwimithambo yegazi ehambisa igazi entliziyweni, nto leyo ebangela ukuba inciphe. Le yeyona nto ibangela ukuhlaselwa yintliziyo.
• Uhlaselo lwentliziyo / Isifo sentliziyo: Xa umthambo wentliziyo uvalekile ngokupheleleyo, ukuhanjiswa kwegazi kwimisipha yentliziyo kuyanqanyulwa, nto leyo ebangela ukuba imisipha yentliziyo ife.
• Ukungaphumeleli kwentliziyo okubangelwa kukunganyamezelani:Ukubuthathaka kwamandla okumpompa kwentliziyo. Oku kwenza ingakwazi ukupompa igazi elaneleyo emzimbeni.
• Uxinzelelo lwegazi oluphezulu: Uxinzelelo olukhutshwa ligazi njengoko lihamba ngemithambo yegazi luphezulu kunoluqhelekileyo. Ludla ngokubizwa ngokuba "ngumbulali ongathethiyo" kuba alusoloko lubangela iimpawu.
• Isifo sevalvu yentliziyo: Iingcango zentliziyo, oko kukuthi, iivalvu, azivuli okanye zivalwe kakuhle.

Zithini iimpawu zale meko?

Ukuba unenye okanye ngaphezulu kwezi mpawu, kubaluleke kakhulu ukubona ugqirha ngokukhawuleza .

• Intlungu yesifuba, ukuqina, okanye ukungonwabi.
• Ukubetha kwentliziyo.
• Ubunzima bokuphefumla.
• Ukudinwa, ukuziva ngathi ujikeleza.
• Ukuziva udiniwe kakhulu (Ukudinwa).
• Ukudumba kwemilenze namaqatha.

Ungayigcina njani intliziyo yakho iphilile?

Nangona isifo sentliziyo sisifo esibi kakhulu, iindaba ezimnandi zezokuba singawunciphisa kakhulu lo mngcipheko ngokwenza utshintsho kwindlela esiphila ngayo.

Nazi ezinye izinto ezilula onokuzenza:

• Yitya ukutya okunempilo nentliziyo: Yitya imifuno emininzi, iziqhamo, iimbotyi, kunye neenkozo ezipheleleyo (ezifana nerayisi emdaka kunye nee-oats). Nciphisa ukutya kwakho ioyile, ityuwa, iswekile, kunye nokutya okucutshungulweyo.
• Zilolonge rhoqo: Zimisele ukwenza umthambo onzima ubuncinane imizuzu eli-150 ngeveki. Izinto ezifana nokuhamba ngokukhawuleza, ukubaleka, okanye ukudada zilungile.
• Gcina ubunzima obusempilweni: Ukugcina ubunzima obusempilweni ngobude bakho kunciphisa iingozi ezifana noxinzelelo lwegazi oluphezulu kunye nesifo seswekile.
• Kuphephe ukutshaya ngokupheleleyo: Ukutshaya yenye yezona ntshaba zinkulu zentliziyo. Ukuba ungumtshayi, funa uncedo lokuyeka.
• Lawula uxinzelelo: Uxinzelelo alulunganga entliziyweni. Unganciphisa uxinzelelo ngokwenza izinto ezifana nokucamngca, i-yoga, okanye ukwenza into oyithandayo.
• Jonga uxinzelelo lwakho lwegazi, i-cholesterol, kunye namanqanaba eswekile: Yiya kuxilongwa rhoqo ngugqirha kwaye uqaphele la manqanaba. Ukuba kuyimfuneko, sebenzisa amayeza achazwe ngugqirha wakho ngqo.

Intliziyo yakho sesona sipho sixabisekileyo owakha wasifumana. Luxanduva lwakho ukuyinyamekela kakuhle. Ukuba unenkxalabo malunga nempilo yentliziyo yakho, ungoyiki ukuthetha nogqirha wakho.
