Igazi ligeleza kanjani emzimbeni wakho wonke? (Ukugeleza Kwegazi) Ake sixoxe ngalokhu kalula!

Wake wazibuza ukuthi indaba emangalisayo ngemuva komsindo wenhliziyo yakho ishaya, ukushaya kwenhliziyo okuzwayo lapho ubeka isandla sakho esifubeni sakho? Empeleni, ngaphakathi emizimbeni yethu, kukhona uhlelo lwemithambo yegazi, njengenethiwekhi yemigwaqo edolobheni elincane. Yilokhu okuletha impilo emzimbeni wethu wonke. Kulungile, ake sibone ukuthi le nto emangalisayo ebizwa ngokuthi ukujikeleza kwegazi, noma ukujikeleza kwegazi , isebenza kanjani.

Libaluleke kangakanani igazi?

Sonke siyazi ukuthi igazi liyigugu kangakanani kithi. Kodwa igazi lenzani ngempela emizimbeni yethu? Cabanga ngakho, igazi lifana nesevisi yokulethwa ethuthuke kakhulu emizimbeni yethu.

Izinkonzo igazi elizinikezayo emizimbeni yethu ziyamangalisa ngempela. Kalula nje:

• Uma siphefumula, umoya-mpilo ongena emaphashini uthwalwa yigazi uye kuzo zonke izingxenye zomzimba ezincane, kuwo wonke amaseli.
• Izakhamzimba esizithola ekudleni esikudlayo, okungukuthi, amandla namavithamini umzimba wethu owadingayo, zisatshalaliswa emzimbeni wonke yigazi.
• Futhi, igazi lisiza ekuqoqeni imfucuza, njenge-carbon dioxide , ekhiqizwa umsebenzi wamangqamuzana ethu bese iyithwala iye ezindaweni lapho ikhishwa khona emzimbeni (njengamaphaphu nezinso).
• Akukhona lokhu kuphela, kodwa igazi liphinde lithwale amangqamuzana omzimba alwa nezifo emizimbeni yethu futhi athumele amakhemikhali abalulekile njengama-hormone lapho edingeka khona.

Ngakho-ke, igazi libalulekile ekusekeleni izimpilo zethu nasekulondolozeni impilo yazo zonke izicubu emzimbeni wethu.

Inhliziyo yethu - iphampu emangalisayo esebenza ngokungayeki!

Ukuze lithumele leli gazi emzimbeni wonke, lidinga amandla, akunjalo? Kulungile, yilokho okwenziwa yinhliziyo yethu, noma i-cardiomyocyte. Kufana nephampu enkulu esebenza ngokungayeki usuku lonke, ngisho nalapho silele. Njalo lapho inhliziyo ishaya, igazi elincane liphampuzwa emzimbeni wonke. Lokhu kuyamangalisa kangangokuthi ngokwesilinganiso, inhliziyo yethu ishaya izikhathi ezingaba yikhulu lezinkulungwane ngosuku!

Uhlelo Lwemithambo Yegazi - Inethiwekhi Yomgwaqo Omkhulu Womzimba

Igazi eliphampa inhliziyo aligcini nje ngokusabalala emzimbeni wonke. Linohlelo olukhethekile lwemigwaqo. Lokhu sikubiza ngokuthi uhlelo lokujikeleza kwegazi . Kulesi simiso, igazi lithwalwa ngezinhlobo ezintathu zamapayipi anobukhulu obuhlukene abizwa ngokuthi imithambo yegazi . Njengoba nje idolobha linemigwaqo emikhulu, imigwaqo emincane, kanye nemigwaqo engaphandle.

Lezi zinhlobo ezintathu zemithambo yegazi yilezi:

1. Imithambo yegazi

2. Imithambo yegazi

3. Ama-capillaries

Ake sixoxe ngalolu hlobo ngalunye ngokwehlukana.

Imithambo yegazi - izindlela ezithwala imiyalezo esuka enhliziyweni iye emzimbeni

Imithambo yegazi emikhulu ethwala igazi elihlanzekile, elinomoya-mpilo lisuka enhliziyweni liye kuzo zonke ezinye izicubu . Ngokuvamile iboniswa ngombala obomvu kumadayagramu ngoba iqukethe umoya-mpilo omningi (kodwa empeleni, lonke igazi libomvu!).

• Umthambo omkhulu noyinhloko okhipha igazi enhliziyweni yi -aorta . Ufana nepayipi elikhulu kunawo wonke eliphuma ethangini lamanzi.
• Kusukela kulo mthambo omkhulu, njengamagatsha esihlahla, usakazeka ube yimithambo emincane bese uhamba emzimbeni wonke. Le mithambo ihlinzeka ngegazi ezingalweni, emilenzeni, ekhanda, nakuwo wonke amalungu omzimba.
• Izindonga zemithambo yegazi ziqinile futhi ziqinile, futhi ziyanwebeka ngoba zidinga ukumelana nengcindezi nokulawula ukugeleza kwegazi lapho inhliziyo ipompa igazi ngomfutho ophezulu.

Cabanga ngale mithambo yegazi njengohlelo oluyinhloko lokuphakelwa kwamanzi edolobheni. Yiyo ethwala amanzi ahlanzekile kuwo wonke amakhaya nakuzo zonke izindawo.

Ama-Capillaries - izikhungo zokushintshana ezincane kakhulu

Igazi elivela emithanjeni aliyi ngqo emithanjeni. Phakathi, kukhona inethiwekhi yemithambo yegazi emincane kakhulu, engajiyile njengonwele, efinyelela kuzo zonke izingxenye zomzimba ezincane, kuwo wonke amaseli. Lokhu yilokho esikubiza ngokuthi ama-capillary. Lokhu kufana namabhuloho amancane axhumanisa imithambo yegazi nemithambo yegazi.

• Izindonga zala ma-capillary zincane kakhulu - uma sikhuluma iqiniso, ungqimba olulodwa lweseli luwugqinsi.
• Lezi zindonga ezincane zivumela umoya-mpilo nezakhamzimba ukuthi zilethwe kalula zisuka egazini ziye ezicutshini, kanti i-carbon dioxide neminye imfucuza ibuyiselwe kalula egazini isuka ezicutshini.
• Kalula nje, lawa ma-capillary yilapho kwenzeka khona ukushintshana kwangempela . Kufana nesitolo esincane, lapho izimpahla zishintshaniswa khona.

Le nethiwekhi yama-capillary incane kangangokuthi kuthiwa akukho nelilodwa iseli emzimbeni wethu eliqhele ngaphezu kwemilimitha elilodwa ukusuka kwenye yalezi capillaries. Zisakazeke kakhulu emzimbeni wonke.

Imithambo - Izindlela ezithwala igazi eligcwele udoti zibuyele enhliziyweni

Manje, ngemva kokunikeza umoya-mpilo nezakhamzimba ezicutshini nokuqoqa i-carbon dioxide kanye nemikhiqizo engcolile kuzo, igazi kumele libuyiselwe enhliziyweni. Lowo msebenzi obalulekile wenziwa uhlobo lomthambo wegazi obizwa ngokuthi umthambo. Lokhu kuvame ukuboniswa ngombala oluhlaza okwesibhakabhaka kumadayagramu ngoba leli gazi linomoya-mpilo omncane.

• Imithambo emincane, eqala kuma-capillary, ihlangana kancane kancane ukuze yakhe imithambo emikhulu, ekugcineni iletha igazi enhliziyweni. Njengoba nje imifudlana emincane ihlangana ukuze yakhe umfula omkhulu.
• Ngokuvamile, igazi elinomoya-mpilo omncane kanye ne-carbon dioxide eningi lidlula kulokhu. (Kodwa kukhona okuhlukile kulokhu, futhi yimithambo eletha igazi elihlanzekile lisuka emaphashini liye enhliziyweni - ibizwa ngokuthi imithambo yamaphaphu. Kuyinkimbinkimbi kancane, sizoxoxa ngalokho kamuva).
• Cishe uke waphawula ukuthi ngezinye izikhathi, ezingalweni noma emilenzeni yakho, imithambo ibonakala iluhlaza okwesibhakabhaka ngaphezu kwesikhumba. Leyo imithambo. Imithambo itholakala kancane ngaphezu kwemithambo.
• Umthambo omkhulu othwala igazi lisuka ekhanda nasezingalweni zethu uliyise enhliziyweni ubizwa ngokuthi i-Superior Vena Cava . I-Vena Cava engaphansi ithwala igazi lisuka esiswini nasemilenzeni . Le mithambo emibili emikhulu iqoqa igazi elingcolile lisuka enhliziyweni.
• Izindonga zemithambo zincane kancane futhi azinwebeki kahle kunezemithambo ngoba igazi ligeleza ngemithambo ngengcindezi ephansi.
• Kukhona enye into ebaluleke kakhulu emithanjeni. Futhi leyo ama-valve.. Lezi zifana neminyango evula indlela eyodwa kuphela. Lawa ma-valve asiza igazi ukuthi ligeleze ohlangothini olulodwa kuphela, liye enhliziyweni, futhi alivimbele ukuthi ligeleze libuyele emuva. Lawa ma-valve awusizo kakhulu ekuletheni igazi ngokumelene namandla adonsela phansi, ikakhulukazi ezindaweni ezifana nemilenze.

Uyazi ukuthi lolu hlelo lwemithambo yegazi lude kangakanani?

Ubungeke ukholwe, kodwa uma welula yonke imithambo yegazi, imithambo yegazi, kanye nama-capillary esikhulume ngawo, ngabe angaphezulu kwamakhilomitha angu-96,500 ubude ! Lokho kwanele ukuhambahamba umhlaba izikhathi ezingaphezu kokuphindwe kabili! Akumangalisi yini ukuthi empeleni sinenethiwekhi ende kangaka yemigwaqo emizimbeni yethu?

Ukugeleza kwegazi njalo kanye nendima yenhliziyo

Ngale ndlela, igazi emzimbeni wethu aliyeki ukugeleza ngisho nomzuzwana owodwa. Le nqubo iyaqhubeka ngenkathi siphapheme, silele, sigijima, futhi sidla. Impande yakho konke lokhu ukupompa kwenhliziyo yethu okungapheli. Inhliziyo isebenza njengenjini yalo lonke uhlelo lokujikeleza kwegazi.

Kungani lolu hambo lwegazi lubaluleke kangaka kithi?

Manje cishe usuyaqonda ukuthi lokhu kugeleza kwegazi, noma ukujikeleza kwegazi, kubaluleke kangakanani emizimbeni yethu.

Kalula nje:

• Ukuze wonke amaseli amancane emzimbeni wethu aphile futhi asebenze, lokhu kugeleza kwegazi kumele kwenzeke ngokunembile .
• Amaseli ethu awakwazi ukusebenza ngaphandle komoya-mpilo nezakhamzimba, njengoba nje nemoto ingakwazi ukusebenza ngaphandle kukaphethiloli.
• Futhi, uma imfucuza ingasuswa, amaseli angonakala futhi afe ngisho nokufa.
• Ngezinye izikhathi, uma kuvela izinkinga kule mithambo yegazi, isibonelo, uma ivinjelwa (ngokuqongelela izinto ezifana ne-cholesterol) noma uma ukuqina kwayo kwehla, ukugeleza kwegazi kungaphazamiseka futhi kuvele izifo ezahlukahlukene. Lokhu kungaholela ngisho nasezimeni ezimbi njengokuhlaselwa yinhliziyo kanye nohlangothi.

Yingakho ukugcina ukujikeleza kwegazi okunempilo kubaluleke kakhulu empilweni yethu iyonke.

Izinto ezibaluleke kakhulu okudingeka sizikhumbule

Ngakho-ke, manje usuyaqonda ukuthi inqubo yokujikeleza kwegazi emizimbeni yethu iyinkimbinkimbi, emangalisayo, futhi ebalulekile kangakanani.

Inhliziyo yethu, isitho esincane, ipompa igazi njalo kule nethiwekhi enkulu yemithambo yegazi, inika impilo kuwo wonke amaseli emzimbeni wethu. Uma nje lolu hlelo lusebenza kahle, siphilile futhi siphilile.

Ngakho-ke, kubaluleke kakhulu ukunakekela inhliziyo yethu kanye nalesi simiso sokujikeleza kwegazi, okusho ukulandela imikhuba emihle njengokudla okunempilo, ukuzivocavoca, nokugwema ukubhema. Ngoba lesi simiso esimangalisayo yisona esisigcina siphila!

Igazi , igazi, inhliziyo, ukujikeleza kwegazi, imithambo yegazi, imithambo yegazi, ama-capillary, umoya-mpilo, ukudla okunomsoco
