Kodi munayamba mwadzifunsapo kuti ndi zinthu zingati zodabwitsa zomwe zimachitika m'thupi lathu? Monga momwe zilili ndi misewu mumzinda waukulu, matupi athu ali ndi mitsempha yamagazi yomwe imanyamula magazi m'thupi lonse. Dongosololi limaphatikizapo misewu ikuluikulu (mitsempha yamagazi), misewu yaying'ono, komanso misewu yaying'ono kwambiri yopita ku nyumba. Misewu yaying'ono imeneyo ndi yomwe timaitcha 'Capillaries'. Iyi ndi yomwe imapereka mpweya ndi michere ku selo iliyonse m'thupi lathu ndikusonkhanitsa zinyalala kumeneko. Chifukwa chake lero tikulankhula za mitundu yaying'ono, koma yofunika kwambiri ya mitsempha yamagazi, 'Continuous Capillaries'.
Mwachidule, kodi mitsempha yamagazi imeneyi ndi chiyani?
Tangoganizani mwayitanitsa chinthu pa intaneti. Galimoto yaikulu imachibweretsa mumzinda waukulu, kenako galimoto yaying'ono imachibweretsa mumzinda wanu, ndipo pamapeto pake mnyamata wonyamula katundu pa njinga amabwera n’kubweretsa phukusi pakhomo panu. Umu ndi momwe magazi amayendera m’thupi lathu. Mitsempha ikuluikulu ya magazi (mitsempha yamagazi) yomwe imanyamula magazi ochuluka okosijeni kuchokera mumtima ili ngati magalimoto. Magaziwo akafika m’ziwalo, amagawikana m’mitsempha yaying'ono. Pomaliza, mitsempha yamagazi ndi mitsempha yaying'ono kwambiri yomwe imapereka mpweya ndi zakudya ku selo iliyonse. Monga mnyamata wonyamula katundu uja.
Makoma a mitsempha yamagazi iyi amapangidwa ndi mtundu wapadera wa selo wotchedwa 'maselo a endothelial' . Maselo awa amalumikizana kwambiri ndipo amakonzedwa motsatizana, motero amatchedwa 'continuous'. Iyi ndi mtundu wofala kwambiri wa mitsempha yamagazi yomwe imapezeka m'thupi lathu.
Kodi pali mitundu ya mitsempha yopitilira iyi?
Inde, pali mitundu iwiri ikuluikulu. Kusiyana pakati pawo ndi kukula kwa mipata pakati pa maselo omwe amapanga makoma. Tiyeni tiwone zomwe zili.
| Mtundu wa capillary | Kufotokozera ndi malo |
|---|---|
| Mitsempha yamagazi yosapitirira yopanda mpweya | Mipata pakati pa maselo awa ndi yaying'ono kwambiri. Chifukwa cha izi, tinthu tating'onoting'ono tokha monga madzi, shuga, mahomoni, ndi mpweya timadutsamo. Monga sefa yomwe mumasefa kapu ya tiyi. Izi zimapezeka mu mitsempha yathu, pakhungu, ndi m'mapapo . |
| Mitsempha yamagazi yokhazikika mosalekeza | Izi zili ndi mabowo akuluakulu pang'ono, otchedwa 'fenestrations', pakati pa maselo. Izi zimathandiza kuti zakudya ndi zinthu zina m'magazi zidutse mwachangu. Izi zimapezeka mu impso zathu, m'matumbo ang'onoang'ono, ndi m'matenda a endocrine . |
Pali mtundu wina wotchedwa 'sinusoidal capillaries'. Sizipitirira, zomwe zikutanthauza kuti pali mipata yayikulu pakati pa maselo. Izi zimapezeka m'malo monga chiwindi, ndulu, ndi ma lymph nodes.
Kodi izi zimathandiza bwanji ziwalo m'thupi lathu?
Mitsempha yamagazi yaying'ono iyi ndi gawo lofunikira kwambiri pakugwira ntchito kwa ziwalo zambiri zofunika m'thupi lathu.
Amateteza ubongo
Ubongo wathu ndi chiwalo chomvera kwambiri. Sichingalowe ndi chilichonse. Chitetezo chimenecho chimaperekedwa ndi dongosolo lapadera la mitsempha yamagazi. Timachitcha 'chotchinga cha magazi ndi ubongo' . Chili ngati ofesi ya visa yolowera mdziko lina. Chimangolola zinthu zofunika kwambiri zomwe ubongo umafunikira, monga mpweya ndi madzi, kuti zilowe, ndipo chimaletsa poizoni ndi majeremusi m'magazi kuti asalowe mu ubongo. Izi zimapangidwa ndi mitsempha yamagazi yopanda mpweya yomwe tidakambirana kale.
Kubweretsa mahomoni pamalo oyenera
Mahomoni amapangidwa ndi ma endocrine glands m'thupi lathu. Mahomoni amenewa amafunika kupita ku ziwalo zoyenera m'thupi ndikuwongolera ntchito yawo. Ma capillaries amenewa amapereka 'ntchito yotumizira' mwa kuwonjezera mahomoni amenewo m'magazi ndikuwanyamula kupita nawo kumalo omwe mukufuna.
Amathandiza impso
Ma capillaries amenewa amagwira ntchito yofunika kwambiri pa njira yomwe impso zathu zimasefera magazi ndikupanga mkodzo. Panthawi yosefera, ma capillaries amenewa amathandizanso thupi kuyamwa zinthu monga madzi ndi sodium zomwe limafunikira.
Kusinthana kwa mpweya m'mapapo
Tikamapuma, mpweya umene timapuma umawonjezeredwa m'magazi, ndipo mpweya wa carbon dioxide womwe uli m'magazi umaperekedwa m'mapapo kuti utuluke kudzera m'mitsempha yaying'ono iyi m'mapapo.
Zimathandiza kugaya chakudya.
Tiyenera kugaya chakudya chomwe timadya ndikupereka zakudyazo ku maselo a thupi lathu. M'matumbo ang'onoang'ono, zakudyazi zimalowa m'magazi kudzera m'mitsempha yamagazi. Kenako, zakudyazo zimagawidwa m'thupi lonse.
Kodi ndi matenda ati omwe amakhudza mitsempha yamagazi iyi?
Ngakhale kuti ndi ofunika, pali matenda osiyanasiyana omwe angakhudze mitsempha yaing'ono yamagazi iyi. Ena mwa iwo akhoza kukhala matenda a majini omwe amapezeka pobadwa, pomwe ena angachitike pambuyo pake.
| Matenda a majini (obadwa nawo) | Matenda osakhala a majini (omwe amayamba pambuyo pake) |
|---|---|
| Kusokonekera kwa mitsempha ya m'mitsempha (AVM): Matenda omwe mitsempha ndi mitsempha ya m'mitsempha ya ubongo kapena msana zimakangana, zomwe zimapangitsa kuti mitsempha ya m'mitsempha isamayende bwino. | Ma capillaries osweka: Nthawi zina, kutsokomola kapena kusanza kungawononge mitsempha yamagazi yomwe ili pansi pa khungu. |
| Matenda a hemorrhagic telangiectasia: Matenda omwe amayamba chifukwa cha kukula kosazolowereka kwa mitsempha yamagazi yomwe ingayambitse kuphulika ndi kutuluka magazi mosavuta. | Matenda a Capillary leak: Matenda oopsa omwe kuthamanga kwa magazi kumatsika mwadzidzidzi. Izi zingafunike chithandizo cha ETU. |
| Matenda a Microcephaly-capillary malformation: Ma capillaries otambasuka mwa ana obadwa ndi mutu waung'ono. | Spider nevus: Matenda omwe amaoneka ngati kangaude wokhala ndi kadontho kakang'ono pakati ndi mitsempha yofiira yozungulira. Amafala kwambiri m'malo monga nkhope ndi khosi. |
| Kuwonongeka kwa maso: Kuwonongeka kwa maso chifukwa cha kutuluka kwa magazi kuchokera m'mitsempha yamagazi ya diso. | Vasculitis: Kutupa kwa mitsempha yamagazi. Izi zingayambitse mitsempha yamagazi kutsekeka kapena kuphulika. |
Asayansi akufufuzabe ngati kusintha kwa ntchito ya mitsempha yamagazi imeneyi kumakhudza matenda monga matenda a Alzheimer's, sitiroko, ndi matenda a mitsempha yamagazi .
Kotero, kodi tingasunge bwanji mitsempha yathu yamagazi kukhala yathanzi?
M'manja mwathu kusamalira mitsempha yamagazi yaing'ono koma yamtengo wapataliyi. Sitiyenera kuchita chilichonse chapadera pa izi. Chofunika kwambiri ndikukhala ndi moyo wabwino.
Zinthu zomwe mungachite nthawi zambiri:
- Pewani kusuta: Kusuta fodya ndiye mdani wamkulu wa mitsempha yamagazi. Choncho ngati mukusuta, yesani kusiya.
- Khalani okonzeka kuchitapo kanthu:Kuchita masewera olimbitsa thupi tsiku lililonse kumathandiza kwambiri kuti magazi aziyenda bwino.
- Khalani ndi kulemera kwabwino: Kunenepa kwambiri kumaika magazi m'mitsempha.
- Kuletsa kumwa mowa: Kumwa mowa mopitirira muyeso kumawononga mitsempha yamagazi.
Komanso, ngati muli ndi matenda monga matenda a shuga, kuthamanga kwa magazi , kapena cholesterol yokwera , tsatirani malangizo a dokotala wanu mosamala. Kulamulira matenda amenewa ndikofunikira kwambiri pa thanzi la mitsempha yamagazi.
Tetezani mitsempha yamagazi, makamaka pankhope:
Khungu la pankhope pathu ndi lofewa kwambiri, kotero mitsempha yamagazi kumeneko imatha kuwonongeka mosavuta.
- Mukatsuka nkhope yanu, itsukeni pang'onopang'ono, osaipukuta mwamphamvu.
- Onetsetsani kuti mwagwiritsa ntchito mafuta abwino oteteza ku dzuwa mukatuluka panja.
- Ngati muli ndi vuto la khungu monga rosacea , pitani kwa dokotala ndipo mupeze chithandizo choyenera.
Mwa kusamalira zinthuzi, mutha kusunga minofu ya m'mitsempha yamagazi, yomwe ndi tinthu tating'onoting'ono koma tofunikira kwambiri m'thupi lathu, kukhala ndi thanzi labwino. Ngati muli ndi vuto lililonse kapena kukayikira pankhaniyi, musazengereze kulankhula ndi dokotala wa banja lanu.
Uthenga Wopita Nawo Kunyumba
- Ma capillaries ndi mitsempha yaing'ono kwambiri m'thupi lathu. Ndiwo omwe amanyamula mpweya ndi zakudya ku maselo athu onse.
- Ma capillaries osalekeza ndi mtundu wofala kwambiri. Maselo awo amalumikizana mwamphamvu.
- Chotchinga cha magazi ndi ubongo, chomwe chimateteza ubongo, chimapangidwa ndi mitsempha yamagazi iyi.
- Zinthu monga kusuta fodya, kudya zakudya zosayenera, komanso kusachita masewera olimbitsa thupi zingakhudze thanzi la mitsempha yamagazi.
- Tingathe kuteteza mitsempha yamagazi yofunikayi mwa kukhala ndi moyo wathanzi komanso kuwongolera matenda monga matenda a shuga ndi kuthamanga kwa magazi.
