Umshini omangalisayo emzimbeni wethu: Ake sifunde ngenhliziyo kanye nohlelo lokujikeleza kwegazi!

Wake wazibuza ukuthi umsindo othi “dig dig… dig dig…” uyini uma ubeka isandla sakho esifubeni sakho? Ngezinye izikhathi, ngemva kokugijima nokudlala, lo msindo uyakhula kakhulu, akunjalo? Nokho, lowo ngumshini omangalisayo nobaluleke kakhulu emzimbeni wethu, okungukuthi, indlela inhliziyo yethu esebenza ngayo. Ngaphandle kwale nhliziyo, kanye nohlelo lwemithambo oluxhumana nayo futhi luthwala igazi emzimbeni wonke, besingeke sikwazi ukuphila ngisho nomzuzwana owodwa. Ngakho-ke, namuhla, ake sixoxe ngenhliziyo, ebaluleke kakhulu empilweni yethu, kanye nohlelo lokujikeleza kwegazi. Ake ngikuchazele ngendlela elula kakhulu, ngendlela ongayiqonda.

Iyini inhliziyo? Iphampu enamandla kakhulu emzimbeni wethu!

Kalula nje, inhliziyo yakho ifana nephampu eyenziwe ngenyama esebenza ngokungayeki . Ifana nenjini encane yamanzi, kodwa isebenza ngendlela emangalisayo kakhulu! Inhliziyo yomuntu omdala ojwayelekile ishaya izikhathi eziphakathi kuka-60 no-100 ngomzuzu. Ishaya kancane kancane uma ulele, futhi ishesha kancane uma uzivocavoca, yilokho kanye okwenzekayo.

Cabanga nje, kusukela osukwini lokuzalwa kwakho, le nhliziyo encane ibilokhu isebenza kuwe ngaphandle kokuphumula, kungakhathaliseki ukuthi ulele noma uvukile! Kumangalisa kangakanani lokho?

Ngokushaya kwenhliziyo ngakunye, inhliziyo ipompa igazi emzimbeni wonke. Hhayi igazi kuphela, kodwa leli gazi lithwala umoya-mpilo , obalulekile empilweni. Kufana nemoto eletha ukudla neziphuzo.

Inhliziyo isebenza kanjani? Imfihlo encane!

Kulungile, manje ake sibone ukuthi kwenzekani ngaphakathi kwale nhliziyo. Lokhu kufana nendaba encane.

1. Okokuqala, inhliziyo ipompa igazi elinomoya-mpilo liye kuzo zonke izingxenye ezincane zomzimba wethu, ezibizwa ngamaseli (njengezakhi ezincane ezakha imizimba yethu). Lawa maseli adinga umoya-mpilo ngempela ukuze asebenze futhi aphile.

2. Uma umoya-mpilo usuthunyelwe emaseli, igazi libuyela enhliziyweni. Kodwa manje igazi selinomoya-mpilo ophansi, futhi esikhundleni salokho liqukethe imfucuza eminingi evela emaseli, ikakhulukazi i-carbon dioxide .

3. Manje inhliziyo ithumela leli gazi elingenawo umoya-mpilo, elinothe nge-carbon dioxide emaphashini ukuze lihlanzwe. Kufana nokulithumela endaweni yokuwasha izingubo.

4. Emaphashini, i-carbon dioxide egazini iyasuswa bese ithathelwa indawo yi-oxygen entsha. Yilo moya esiwuthathayo uma siphefumula.

5. Manje, igazi elihlanzekile, elinomoya-mpilo libuyela enhliziyweni.

6. Bese inhliziyo iphinda ipompe lelo gazi emzimbeni wonke.

Lo mjikelezo uqhubeka njalo, ungapheli. Kufana nesiyingi esijikelezayo. Cabanga ukuthi bekuzokwenzekani uma lokhu bekungamiswa ngisho nomzuzwana! Yingakho inhliziyo ingenye yezitho ezibaluleke kakhulu emzimbeni wethu.

Ngakho-ke luyini lolu hlelo lokujikeleza kwegazi? Inethiwekhi yezindlela ezihamba emzimbeni wonke!

Kulungile, sixoxe ngenhliziyo. Manje ake sibone ukuthi igazi elimpontshwa yinhliziyo lihanjiswa kanjani emzimbeni wonke. Yilokho esikubiza ngokuthi uhlelo lokujikeleza kwegazi . Lokhu kufana nenethiwekhi yemigwaqo ezweni lakithi. Yonke imigwaqo emikhulu, imigwaqo emincane, kanye nemigwaqo engezansi iyahlangana ukuze yakhe lolu hlelo. Le migwaqo siyibiza ngokuthi imithambo yegazi noma imithambo yegazi .

Kunezinhlobo ezimbili eziyinhloko zale mithambo yegazi:

• Imithambo Yegazi: Lena yimithambo emikhulu ethwala igazi isuka enhliziyweni. Le mithambo ithwala igazi elihlanzekile neligcwele umoya-mpilo elikhishwa yinhliziyo liye kuzo zonke izingxenye zomzimba. Izindonga zayo zijiyile kancane ngoba kufanele imelane nomfutho wegazi ophakeme ovela enhliziyweni.
• Imithambo: Lena yimithambo yegazi eqoqa igazi ezingxenyeni ezahlukene zomzimba bese ilibuyisela enhliziyweni . Leli gazi livame ukuba nomoya-mpilo ophansi futhi ligcwele i-carbon dioxide neminye imfucuza.

Enye imfihlo encane: Ama-Capillaries

Phakathi kwemithambo yegazi nemithambo yegazi, kukhona inethiwekhi yemithambo yegazi emincane kakhulu, engajiyile njengonwele. Lezi zibizwa ngokuthi ama-capillary . Zifana nemigwaqo emincane eseceleni eholela emigwaqweni emikhulu eya ezindlini. I-oksijini nezakhamzimba kuyashintshaniswa phakathi kwamangqamuzana, futhi imfucuza iqoqwa kusuka kwamangqamuzana iye egazini ngalezi zinhlayiya. Lokhu kusho ukuthi lesi yisikhungo sokushintshana esibaluleke kakhulu.

Iyiphi insizakalo esiyitholayo kulolu hlelo?

Izinsizakalo ezinikezwa yinhliziyo kanye nohlelo lokujikeleza kwegazi ziningi kakhulu. Bheka:

1. Ukuhlinzekwa komoya-mpilo: Njengoba sesishilo kakade, wonke amaseli emzimbeni wethu adinga umoya-mpilo ukuze aphile futhi asebenze. Lo moya-mpilo unikezwa kuwo wonke amaseli yilolu hlelo, njengokungathi ulethwa ekhaya.

2. Ukusatshalaliswa kwezakhamzimba: Ukudla esikudlayo kunikeza imizimba yethu amandla nokukhula. Uma lokhu kudla sekugayiwe, izakhamzimba - ezifana namavithamini, amaprotheni, namafutha - zithwalwa emzimbeni wonke ziye lapho zidingeka khona yigazi.

3. Ukuthutha Ama-hormone : Ama-hormone ayizithunywa zamakhemikhali ezilawula yonke imisebenzi emizimbeni yethu. Isibonelo, la ma-hormone athinta izinto ezifana nendlela esikhula futhi sithuthuke ngayo, kanye nendlela esilawula ngayo imizwa yethu . La ma-hormone aphinde athuthwe aye ezingxenyeni zomzimba ezidingekayo yigazi.

4. Ukususa imfucuza: Uma amangqamuzana ethu esebenza, akhiqiza imfucuza. Kufana nentuthu ephuma efektri. Omunye wemfucuza eyinhloko yi-carbon dioxide. Igazi lithatha le mfucuza emaselini bese liyiyisa ezithweni zomzimba (njengamaphaphu nezinso) eziyisusa emzimbeni.

Kubaluleke kakhulu ukuthi lokhu kugeleza kwegazi kuhlale kuyindlela eyodwa . Kufana nomgwaqo "ohamba ngendlela eyodwa". Kunezindlela ezahlukene zegazi elinomoya-mpilo, kanye nezindlela ezahlukene zegazi elinomoya-mpilo. Ngaphandle kwalokho, konke kungadideka futhi kubangele isiphithiphithi esikhulu, akunjalo?

Ingabe kufanele sivikele lolu hlelo oluhle kangaka?

Yebo, kunjalo! Cabanga ukuthi kungaba yinkinga engakanani uma iphampu yamanzi namapayipi amanzi endlini yakho kungaphuka? Kunjalo nangenhliziyo nemithambo yegazi. Uma lokhu kungasebenzi kahle, umzimba wethu wonke uzoba senkingeni.

Ngakho-ke, kungumthwalo wethu ukugcina lolu hlelo oluyigugu luphilile.Izinto ezilula njengokudla ukudla okunomsoco, ukuzivocavoca nsuku zonke, ukugwema imikhuba emibi njengokubhema , kanye nokujabula kungasiza kakhulu ekugcineni inhliziyo yethu kanye nohlelo lokujikeleza kwegazi kuphilile. Uma unezifo ezithile, njengesifo sikashukela noma umfutho wegazi ophakeme , kubalulekile futhi ukuzilawula kahle ngokweseluleko sezokwelapha.

Ake sikhumbule nje ukuthi sikhulume ngani namuhla?

Kulungile, ngakho-ke, nazi izinto ezibaluleke kakhulu okudingeka uzikhumbule kulokho esikhulume ngakho namuhla:

• Inhliziyo ingumshini omangalisayo opompa igazi emizimbeni yethu yonke, osebenza njalo.
• Ngokushaya kwenhliziyo ngakunye, igazi elinomoya-mpilo lihamba emzimbeni wonke, bese igazi elinomoya-mpilo ocebile libuyela enhliziyweni, lihlanzwe ngamaphaphu, bese uhambo luqala futhi. Lo mjikelezo uyaqhubeka.
• Uhlelo lokujikeleza kwegazi luyinethiwekhi yemithambo yegazi (imithambo yegazi, imithambo yegazi, ama-capillary) ethwala igazi lisuka enhliziyweni liye futhi lisuka emzimbeni.
• Lolu hlelo yilapho amangqamuzana omzimba wethu ethola khona umoya-mpilo, izakhamzimba, nama-hormone , futhi asuse imfucuza emaseli.
• Lonke lolu hlelo lusebenza kahle kakhulu, njengemigwaqo eya ohlangothini olufanayo .

Ngakho-ke, ubonile ukuthi le nhliziyo nendlela igazi eligeleza ngayo emzimbeni wethu kumangalisa futhi kubaluleke kangakanani. Ngakho-ke, ukuqaphela lokhu nokuzama ukugcina lolu hlelo luphilile kuwusizo olukhulu kuwe. Uma uneminye imibuzo, ungabuza udokotela ngaphandle kokwesaba.
