Makina odabwitsa m'thupi lathu: Tiyeni tiphunzire za Mtima ndi Dongosolo Loyenda M'magazi!

Kodi munayamba mwadzifunsapo kuti mawu akuti “dig dig… dig dig…” ndi otani mukayika dzanja lanu pachifuwa panu? Nthawi zina, mutatha kuthamanga ndi kusewera, mawuwa amamveka kwambiri, sichoncho? Chabwino, ndiye makina odabwitsa komanso ofunikira kwambiri m'thupi lathu, ndiko kuti, momwe mtima wathu umagwirira ntchito. Popanda mtima uwu, ndi mitsempha yomwe imalumikizana nawo ndikunyamula magazi m'thupi lonse, sitingathe kukhala ndi moyo ngakhale sekondi imodzi. Chifukwa chake, lero, tiyeni tikambirane za mtima, womwe ndi wofunika kwambiri pa miyoyo yathu, ndi kayendedwe ka magazi. Ndiloleni ndikufotokozereni m'njira yosavuta, m'njira yomwe mungamvetse.

Kodi mtima ndi chiyani? Pampu yamphamvu kwambiri m'thupi lathu!

Mwachidule, mtima wanu uli ngati pampu yopangidwa ndi mnofu yomwe imagwira ntchito mosalekeza . Uli ngati injini yamadzi, koma umagwira ntchito modabwitsa kwambiri! Mtima wa munthu wamkulu umagunda pakati pa nthawi 60 ndi 100 pamphindi. Umagunda pang'onopang'ono mukagona, ndipo umathamanga pang'ono mukamachita masewera olimbitsa thupi, ndicho chikhalidwe chake.

Tangoganizirani, kuyambira tsiku lomwe munabadwa, mtima waung'ono uwu wakhala ukukugwirani ntchito popanda kupuma, kaya mukugona kapena mukudzuka! Kodi zimenezo n'zodabwitsa bwanji?

Pakugunda kulikonse kwa mtima, mtima umapopa magazi m'thupi lathu lonse. Sikuti magazi okha, komanso magazi awa amanyamula mpweya , womwe ndi wofunikira pa moyo. Uli ngati galimoto yopereka chakudya ndi zakumwa.

Kodi mtima umagwira ntchito bwanji? Chinsinsi pang'ono!

Chabwino, tsopano tiyeni tiwone zomwe zikuchitika mkati mwa mtima uwu. Izi zili ngati nkhani yaying'ono.

1. Choyamba, mtima umapompa magazi okhala ndi mpweya wochuluka kupita ku gawo lililonse laling'ono la thupi lathu, lotchedwa maselo (monga tinthu tating'onoting'ono tomwe timapanga matupi athu). Maselo amenewa amafunikira mpweya wochuluka kuti agwire ntchito ndikukhala ndi moyo.

2. Mpweya ukangoperekedwa ku maselo, magazi amabwerera kumtima. Koma tsopano magazi amakhala ndi mpweya wochepa, ndipo m'malo mwake amakhala ndi zinyalala zambiri kuchokera ku maselo, makamaka carbon dioxide .

3. Tsopano mtima umatumiza magazi amenewa omwe alibe mpweya wokwanira, okhala ndi mpweya woipa wa carbon dioxide m'mapapo kuti ayeretsedwe. Zili ngati kuwatumiza ku malo ochapira zovala.

4. M'mapapo, mpweya wa carbon dioxide m'magazi umachotsedwa ndipo umalowedwa m'malo ndi mpweya watsopano. Ndi mpweya umenewu umene timalandira tikamapuma.

5. Tsopano, magazi oyera, okhala ndi mpweya akubwerera mumtima.

6. Kenako mtima umapopa magaziwo m'thupi lonse kachiwiri.

Kuzungulira kumeneku kumachitika mosalekeza, kosatha. Kuli ngati kuzungulira kozungulira. Tangoganizirani zomwe zingachitike ngati izi zitayima ngakhale kwa sekondi imodzi! Ndicho chifukwa chake mtima ndi chimodzi mwa ziwalo zofunika kwambiri m'thupi lathu.

Kodi dongosolo lozungulira magazi limeneli ndi chiyani? Njira zomwe zimayenda m'thupi lonse!

Chabwino, takambirana za mtima. Tsopano tiyeni tiwone momwe magazi omwe amapopedwa ndi mtima amayendera thupi lonse. Ndicho chimene timachitcha kuti dongosolo lozungulira magazi . Izi zili ngati netiweki ya misewu m'dziko lathu. Misewu yonse ikuluikulu, misewu yaying'ono, ndi njira zopita kufupi zimagwirira ntchito pamodzi kuti zipange dongosololi. Timatcha misewu iyi kuti mitsempha yamagazi kapena mitsempha yamagazi .

Pali mitundu iwiri ikuluikulu ya mitsempha yamagazi iyi:

• Mitsempha yamagazi: Iyi ndi mitsempha ikuluikulu yomwe imanyamula magazi kuchokera mumtima. Mitsempha iyi imanyamula magazi oyera okhala ndi mpweya wochuluka omwe amapopedwa ndi mtima kupita nawo mbali zonse za thupi. Makoma awo ndi okhuthala pang'ono chifukwa amafunika kupirira kuthamanga kwa magazi kuchokera mumtima.
• Mitsempha: Iyi ndi mitsempha yamagazi yomwe imasonkhanitsa magazi kuchokera m'mbali zosiyanasiyana za thupi ndikubweza kumtima . Magazi awa nthawi zambiri amakhala ndi mpweya wochepa komanso amakhala ndi mpweya woipa wambiri ndi zinyalala zina.

Chinsinsi china chaching'ono: Ma Capillaries

Pakati pa mitsempha ndi mitsempha, pali netiweki ya mitsempha yaing'ono kwambiri, yopyapyala, yosakhuthala kuposa tsitsi limodzi. Mitsempha imeneyi imatchedwa ma capillaries . Ili ngati misewu yaying'ono yochokera m'misewu ikuluikulu kupita ku nyumba. Mpweya ndi zakudya zimasinthidwa pakati pa maselo, ndipo zinyalala zimasonkhanitsidwa kuchokera ku maselo kupita m'magazi kudzera m'mitsempha iyi. Izi zikutanthauza kuti iyi ndiye malo ofunikira kwambiri osinthira magazi.

Kodi timapeza chithandizo chotani kuchokera ku dongosololi?

Ntchito zomwe mtima ndi kayendedwe ka magazi zimatipatsa n'zochuluka kwambiri. Taonani izi:

1. Kupereka mpweya: Monga tanenera kale, selo lililonse m'thupi lathu limafunikira mpweya kuti likhale ndi moyo ndi kugwira ntchito. Mpweya umenewu umaperekedwa ku selo lililonse ndi dongosololi, ngati kuti ukubweretsedwa kunyumba.

2. Kugawa zakudya: Chakudya chomwe timadya chimapatsa matupi athu mphamvu ndi kukula. Chakudyachi chikagayidwa, zakudya monga mavitamini, mapuloteni, ndi mafuta zimanyamulidwa m'thupi lonse kupita komwe magazi amafunikira.

3. Kunyamula Mahomoni : Mahomoni ndi mankhwala omwe amalamulira ntchito iliyonse m'thupi lathu. Mwachitsanzo, mahomoni amenewa amakhudza zinthu monga momwe timakulira ndikukula, komanso momwe timalamulira malingaliro athu . Mahomoni amenewa amasamutsidwanso kupita ku ziwalo zofunika za thupi ndi magazi.

4. Kuchotsa zinyalala: Maselo athu akamagwira ntchito, amapanga zinyalala. Zili ngati utsi wochokera ku fakitale. Chimodzi mwa zinyalala zazikulu ndi carbon dioxide. Magazi amatenga zinyalalazi kuchokera ku maselo n’kuzitengera ku ziwalo (monga mapapo ndi impso) zomwe zimazichotsa m’thupi.

Ndikofunikira kwambiri kuti kuyenda kwa magazi nthawi zonse kukhale kopita mbali imodzi . Kuli ngati msewu "wopita mbali imodzi". Pali njira zosiyana za magazi okhala ndi mpweya, ndi njira zosiyana za magazi okhala ndi mpweya wa carbon dioxide. Kupanda kutero, chilichonse chingasokonezeke ndikuyambitsa chisokonezo chachikulu, eti?

Kodi tiyenera kuteteza dongosolo labwino ili?

Inde, ndithudi! Tangoganizirani mavuto angati ngati pampu yamadzi ndi mapaipi amadzi m'nyumba mwanu atasweka? Momwemonso mtima ndi mitsempha yamagazi. Ngati izi sizigwira ntchito bwino, thupi lathu lonse lidzakhala m'mavuto.

Chifukwa chake, ndi udindo wathu kusunga dongosolo lamtengo wapatalili kukhala labwino.Zinthu zosavuta monga kudya zakudya zopatsa thanzi, kuchita masewera olimbitsa thupi tsiku ndi tsiku, kupewa zizolowezi zoipa monga kusuta fodya , komanso kukhala osangalala zingathandize kwambiri kuti mtima wathu ndi kayendedwe ka magazi zikhale zathanzi. Ngati muli ndi matenda enaake, monga matenda a shuga kapena kuthamanga kwa magazi , ndikofunikiranso kuwaletsa bwino malinga ndi upangiri wa dokotala.

Tiyeni tikumbukire zomwe tidakambirana lero?

Chabwino, nazi zinthu zofunika kwambiri zomwe muyenera kukumbukira kuchokera pa zomwe takambirana lero:

• Mtima ndi makina odabwitsa omwe amapopa magazi m'thupi lathu lonse, ndipo amagwira ntchito nthawi zonse.
• Pakugunda kulikonse kwa mtima, magazi okhala ndi mpweya wambiri amayendayenda m'thupi lonse, kenako magazi okhala ndi mpweya wambiri wa carbon dioxide amabwerera kumtima, amatsukidwa ndi mapapo, ndipo ulendowo umayambiranso. Kuzungulira kumeneku kumapitirira.
• Dongosolo lozungulira magazi ndi gulu la mitsempha yamagazi (mitsempha, mitsempha, ndi mitsempha yamagazi) yomwe imanyamula magazi kuchokera pamtima kupita ndi kuchokera m'thupi.
• Dongosolo ili ndi komwe maselo a thupi lathu amalandira mpweya, zakudya, ndi mahomoni , ndikuchotsa zinyalala m'maselo.
• Dongosolo lonseli limagwira ntchito bwino kwambiri, ngati misewu yopita mbali imodzi .

Kotero, mwaona kufunika kwa mtima uwu komanso momwe magazi amayendera mkati mwa thupi lathu. Chifukwa chake, kudziwa izi ndikuyesetsa kusunga dongosololi kukhala lathanzi kungakuthandizeni kwambiri. Ngati muli ndi mafunso ena, mutha kufunsa dokotala popanda mantha.
