Yintoni intliziyo? Makhe sithethe ngale njini incinci ngokweenkcukacha!

Ngaba wakha wazibuza ukuba isandi 'sokugrumba' esihlala sihleli sivela esifubeni sakho sivela phi, kwaye yintoni ebangela oko? Yintliziyo yethu, ilungu elincinci kodwa elinamandla kakhulu elifana nenjini elinika ubomi emizimbeni yethu. Namhlanje, siza kuthetha ngale nxalenye imangalisayo, indlela esebenza ngayo, izifo ezibangelwa yiyo, kunye nento esinokuyenza ukuze siyigcine isempilweni.

Yintoni kanye kanye intliziyo?

Ngamafutshane, intliziyo yakho sisitho esincinci, kodwa esibaluleke kakhulu, esilingana nenqindi yakho. Ifana nepompo yegazi ephambili emzimbeni wethu. Ipompa igazi kuwo wonke umzimba wethu. Lo matshini umangalisayo wenziwe yimisipha kunye nezicubu zomzimba.

Intliziyo yakho inamagumbi amane aphambili, njengamagumbi angaphakathi endlwini. Igazi lingena kula magumbi lize lihlale apho okwethutyana ngaphambi kokuba likhutshwe liye kwamanye amalungu omzimba. Intliziyo ibetha ngeempembelelo zombane. Ezi mpembelelo zihambisa igazi kula magumbi. Ingqondo yakho kunye nenkqubo yemithambo-luvo zilawula ukusebenza kwentliziyo.

Ngoko ke, kwenzeka ntoni ngokwenene entliziyweni?

Umsebenzi oyintloko wentliziyo kukupompa igazi emzimbeni wonke . Eli gazi linika zonke iiseli emzimbeni wethu ioksijini kunye nezondlo ezizidingayo. Likwathwala inkunkuma, efana nekhabhoni diokside, eveliswa ziiseli ize izise kwezinye izitho apho zinokususwa khona.

Ukongeza, intliziyo yakho yenza ezinye izinto:

• Ilawula isantya kunye nesingqisho sentliziyo yakho.
• Inceda ukugcina uxinzelelo lwegazi lwakho lukwinqanaba elifanelekileyo.

Intliziyo ayizenzi ezi zinto yodwa. Isebenza kunye nezinye iinkqubo:

• Inkqubo Yeemvakalelo: Inkqubo yeemvakalelo inceda ekulawuleni izinga lentliziyo yakho. Ithumela imiqondiso yokunciphisa izinga lentliziyo yakho xa ulele kwaye ikhawulezise xa uxinezelekile. Cinga nje ngendlela intliziyo yakho ebetha ngayo ngaphambi kokuba ubhale uvavanyo!
• Inkqubo ye-Endocrine :Le nkqubo ikhupha iihomoni . Ezi homoni zixelela imithambo yegazi yakho ukuba inciphe okanye ivuleke. Oku kuchaphazela uxinzelelo lwegazi lakho. Umzekelo, iihomoni ezivela kwi -thyroid gland yakho zinokuchaphazela indlela intliziyo yakho ebetha ngayo ngokukhawuleza okanye kancinci.

Zithini iindawo zentliziyo? Kufana nendlu!

Singacinga ngendawo yentliziyo efana nendawo yendlu enkulu. Jonga le nkcazo:

• Iindonga: Njengeendonga zendlu.
• Amagumbi: Angathathwa njengamagumbi.
• Iivalvu: Njengeengcango zamagumbi, zinokuvula zize zivale.
• Imithambo yegazi : Njengenkqubo yemibhobho yamanzi endlwini.
• Inkqubo yokuhambisa umbane: Njengenkqubo yocingo lombane enika umbane ekhayeni.

Iindonga zentliziyo

Iindonga zentliziyo yakho zenziwe zimisipha ezifinyela kwaye zande ukuze zincede ekupompeni igazi emzimbeni wakho wonke. Iindonga zentliziyo zahlulwe zibe ngamacala asekunene nasekhohlo sisicwili semisipha esibizwa ngokuba yi-septum .

Kukho iileya ezintathu eludongeni lwentliziyo:

• I-Endocardium: Ingaphakathi le-layer.
• I-Myocardium: Umaleko ophakathi wemisipha. Yiyo le nto inegalelo elikhulu ekubetheni kwentliziyo.
• I-Epicardium: Umaleko ongaphandle okhuselayo.

Le epicardium ngomnye umaleko we -pericardium yakho. I-pericardium sisingxobo esikhuselayo esijikeleze intliziyo yakho yonke. Ivelisa ulwelo lokuthambisa intliziyo kwaye ithintele ukuba ingangqubani nezinye izitho zomzimba.

Amagumbi entliziyo

Intliziyo yakho inamagumbi amane ahlukeneyo, njengamagumbi amane. Kukho amagumbi amabini aphezulu (i-atria) kunye namagumbi amabini asezantsi (ii-ventricles), kwicala lasekunene nelasekhohlo lentliziyo.

• I-atrium yasekunene: Imithambo emibini emikhulu ingenisa igazi elingenaoksijini kwi-atrium yasekunene. I-vena cava ephezulu ingenisa igazi elivela kwiindawo eziphezulu zomzimba. I-vena cava engaphantsiEmva koko i-atrium yasekunene ipompa eli gazi kwi-ventricle yasekunene.
• I-ventricle yasekunene: Le gumbi lisezantsi lasekunene lithumela igazi elingenaoksijini emiphungeni nge -pulmonary artery . Emva koko imiphunga iphinda i-oxygene egazini.
• I-atrium yasekhohlo: Emva kokuba igazi lifakwe ioksijini yimiphunga, imithambo yemiphunga izisa igazi elineoksijini eninzi kwi-atrium yasekhohlo. Eli gumbi liphezulu limpompa igazi kwi-ventricle yasekhohlo.
• I-ventricle yasekhohlo: I-ventricle yasekhohlo inkulu kancinci kune-ventricle yasekunene. Oku kungenxa yokuba ipompa igazi elineoksijini emzimbeni wonke. Ngoko ke ifuna amandla angakumbi.

Iivalvu zentliziyo

Iivalvu zentliziyo yakho zifana neengcango eziphakathi kwamagumbi entliziyo yakho. Ziyavuleka zize zivale ukuze igazi lihambe. Zikwathintela igazi ukuba lingahambi ngendlela engafanelekanga. Ayimangalisi loo nto?

Iivalvu ze-Atrioventricular (AV)

Ezi valve zivuleka phakathi kwamagumbi aphezulu nasezantsi entliziyo yakho. Nazi:

• Ivalvu yeTricuspid: Ucango oluphakathi kwe-atrium yakho yasekunene kunye ne-ventricle yasekunene.
• Ivalvu yeMitral: Ucango oluphakathi kwe-atrium yakho yasekhohlo kunye ne-ventricle yasekhohlo.

Iivalvu zeSemilunar (SL)

Ezi valve ziyavuleka xa igazi liphuma emithanjeni yakho. Nazi:

• Ivalvu ye-Aortic: Ivuleka njengoko igazi liphuma kwi-ventricle yakho yasekhohlo lisiya kwi-aorta (umthambo oyintloko othwala igazi elineoksijini emzimbeni).
• Ivalvu yemiphunga: Ivula xa igazi liphuma kwi-ventricle yakho yasekunene lisiya kwimithambo yemiphunga (uhlobo olulodwa lomthambo othwala igazi elingenaoksijini ukuya emiphungeni).

Ivazi yegazi

Intliziyo yakho ipompa igazi ngeentlobo ezintathu eziphambili zemithambo yegazi:

• Imithambo yegazi: Le ithwala igazi elineoksijini eninzi ukusuka entliziyweni ukuya kwizicubu zomzimba. Nangona kunjalo, imithambo yegazi yakho yemiphunga yahlukile, ithwala igazi elineoksijini encinci ukuya emiphungeni.
• Imithambo: Le ibuyisela igazi eliphelelwe yioksijini entliziyweni.
• IiCapillaries: Ezi zimithambo yegazi emihle kakhulu. Igazi elinomoya-mpilo omninzi kwaye ukutshintshiselana kwegazi okungenawo umoya-mpilo kakuhle ngezi capillaries.

Inkqubo yokuqhuba umbane – 'umbane' entliziyweni

Inkqubo yokuhambisa umoya entliziyweni ifana neentambo zombane endlwini. Ilawula isigqi kunye nesantya sokubetha kwentliziyo yakho. Imiqondiso iqala phezulu kwentliziyo ize yehle. Le nkqubo yokuhambisa umoya iquka:

• I-Sinoatrial node (SA):Imiqondiso eyenza ukubetha kwentliziyo iphuma apha. Yiyo loo nto ibizwa ngokuba yi-'pacemaker yendalo' yentliziyo.
• I-Atrioventricular node (AV): Iqhuba imiqondiso yombane ukusuka kumagumbi aphezulu entliziyo ukuya kumagumbi asezantsi.
• Inqwaba yamasebe akhe, asekhohlo nasekunene, kunye neefayibha zePurkinje: Ezi zezona zinto zenza iiseli zentliziyo yakho zifinyeze kwaye zipompe igazi.

Ziziphi izifo eziqhelekileyo ezichaphazela intliziyo?

Isifo sentliziyo sesinye sezifo eziqhelekileyo. Enyanisweni, kwamanye amazwe, sesona sizathu siphambili sokufa.

Nazi ezinye zezifo eziqhelekileyo ezinokuchaphazela intliziyo yakho:

• I-Arrhythmia: Isantya sentliziyo esikhawulezayo kakhulu, esicothayo kakhulu, okanye esingahambelaniyo.
• I-Cardiomyopathy : Ukuqina okungaqhelekanga, ukwanda, okanye ukuqina kwemisipha yentliziyo.
• Ukungasebenzi kakuhle kwentliziyo: Intliziyo iba lukhuni okanye ibe buthathaka kangangokuba ayikwazi ukupompa igazi ngokufanelekileyo.
• Isifo semithambo yegazi: Ukuqokelelwa kwamafutha (i-plaque buildup) ngaphakathi kwimithambo yegazi, okuyenza inciphe.
• Uhlaselo lwentliziyo / Isifo sentliziyo: Ukuvaleka ngequbuliso komthambo wentliziyo, nto leyo ethintela inxalenye yemisipha yentliziyo ukuba ingafumani ioksijini.
• Isifo sevalvu yentliziyo: Ivalvu yentliziyo engasebenzi kakuhle.
• Uxinzelelo lwegazi oluphezulu: Igazi lakho lityhala ngamandla eludongeni lwemithambo yakho yegazi.
• I-cholesterol ephezulu: Ukwanda kwamafutha egazini lakho.

Ungayigcina njani intliziyo yakho iphilile?

Ukuba unemeko echaphazela intliziyo yakho,Kubalulekile ukulandela isicwangciso sonyango sikagqirha wakho ngokuchanekileyo. Kukwakho notshintsho oluthile kwindlela ophila ngayo onokulwenza ukuze intliziyo yakho ihlale isempilweni.
