Kodi mukudziwa mitsempha yamagazi yaying'ono koma yamphamvu (Arterioles) m'thupi lathu?

Kodi munayamba mwadzifunsapo momwe magazi amayendera m'matupi athu? Mu ulendowu womwe umatengera magazi kuchokera mumtima kupita ku ziwalo zonse za thupi, pali magulu ang'onoang'ono koma ofunikira kwambiri omwe amachita gawo losawoneka. Amatchedwa `(Arterioles)`. Mwachidule, awa ndi mitsempha yamagazi yaying'ono kwambiri. Lero, tikambirana za `(Arterioles)` awa, ntchito yomwe amagwira, komanso momwe angawasungire athanzi.

Kodi `(Arterioles)` ndi chiyani? Kodi ali kuti?

Chabwino, tiyeni choyamba tiwone zomwe `(Arterioles)` (zotchedwa `arterioles') izi zili. Mukudziwa kuti magazi amayenda kuchokera mumtima mwathu kupita ku thupi kudzera m'mitsempha ikuluikulu yamagazi, kutanthauza mitsempha. Mitsempha ikuluikulu imeneyo imagawidwa m'njira zazing'ono kwambiri, zopyapyala zamagazi, osati ngakhale zokhuthala ngati tsitsi. Imatchedwa `(Arterioles).` Monga misewu yaying'ono yam'mbali yomwe imagawanika ndi msewu waukulu. `(Arterioles)` awa ndi njira zazing'ono kwambiri, zopyapyala zamagazi zomwe zimanyamula magazi kupita ku `(Capillaries)`. Tangoganizirani, `(Capillaries)` awa ali ngati malo osinthira magazi. Pamenepo ndi pomwe minofu ndi ziwalo za thupi lathu zimalandira mpweya ndi michere yomwe zimafunikira kuchokera m'magazi, ndipo zinyalala zomwe zili m'minofu imeneyo zimabwerera kumagazi. Kuti zithandize kusinthaku, mitsempha yaying'ono kwambiri, yotchedwa ma venules (iyi ndi yomwe imanyamula magazi kubwerera kumtima), imalumikizidwanso ndi mitsempha iyi. Ndiye, kodi ma arterioles awa ali kuti? Kwenikweni, kulikonse m'thupi lathu! Chifukwa selo lililonse ndi minofu m'thupi lathu zimafunikira mpweya ndi michere. Chifukwa chake, njira zazing'onozi zimafalikira mthupi lonse ngati netiweki. Mwachidule, kukula kwa ma arterioles ndi pafupifupi ma micrometer 100 mpaka 7. Ndiko kuti, mtengo wake ndi wochepa kwambiri, pafupifupi ma millimeter 0.30 mpaka 0.01. Kukhuthala kwa khoma ndi pafupifupi ma millimeter 0.02. Ngakhale ndi zazing'ono, ntchito yawo ndi yayikulu kwambiri.

Kodi ntchito yaikulu ya `(Arterioles)` ang'onoang'ono awa ndi yotani?

`(Arterioles)` ang'onoang'ono awa amachita zambiri kuposa momwe mukuganizira. Chofunika kwambiri ndikulamulira kuyenda kwa magazi ndi kuthamanga kwa magazi m'thupi lathu lonse. Tangoganizani, `(Arterioles)` awa amapanga 80% ya kukana komwe kumachitika magazi akamayenda kudzera m'mitsempha yamagazi ya thupi lathu! Mwanjira ina, njira zazing'onozi zimayang'anira ndikulamulira momwe magazi athu amayendera mwachangu komanso ndi mphamvu yomwe magazi athu amayendera m'thupi lonse, komanso kuchuluka kwa magazi omwe amapita ku minofu yathu nthawi iliyonse. Kodi mukudziwa momwe izi zimachitikira? Makoma a `(Arterioles)` ali ndi minofu. Minofu iyi imatha kufupika (kulimbitsa) ndikukulitsa (kukula). Monga momwe kukanikiza chitoliro chamadzi kumasintha liwiro la madzi.

• Ma ``(Arterioles)`` amenewa amatha kupirira kupanikizika kwa magazi ochokera mumtima.
• Amathanso kufinya magazi pamene akuyenda kuchokera mumtima kupita ku ziwalo zina za thupi. Umu ndi momwe kuthamanga kwa magazi kosalekeza komanso kokhazikika kumakhalira.

Chinthu china n’chakuti imagwira ntchito ngati cholumikizira pakati pa mitsempha ikuluikulu ndi mitsempha yaying’ono kwambiri, kutanthauza kuti imagwira ntchito ngati "wapakati". "Arterioles" zimenezi zimathandiza kupereka mpweya ndi zakudya kuchokera ku mitsempha ikuluikulu kupita ku minofu kudzera m'mitsempha yotereyi, komanso kusonkhanitsa zinyalala kuchokera ku minofu kudzera m'mitsempha yamagazi ndikuzipereka ku mitsempha, yotchedwa "Venule".

Kodi `(Arterioles)` zimathandiza bwanji ziwalo zathu zina?

Monga ndanenera kale, `(Arterioles)` amapezeka m'thupi lonse, kotero amathandiza chiwalo chilichonse m'thupi lathu. Nazi zitsanzo zina:

• Pakhungu lathu: Ena mwa ma `(Arterioles)` amafinya ndipo amathandiza kuti magazi azilowa m'thupi. Kenako timamva kuzizira pang'ono, ndipo thupi limakhala lofunda. Komanso, ma `(Arterioles)` pakhungu akamakula (kukulirakulira), amawonjezera kuyenda kwa magazi kupita ku khungu ndi miyendo. Kenako kutentha kuchokera m'thupi kumatuluka, ndipo timamva kuzizira.
• Impso : Glomerulus ( mtsempha wamagazi waung'ono womwe umasefa magazi) m'impso umalumikizidwa ndi netiweki ya mitsempha yamagazi yotchedwa afferent arterioles. Izi zimatha kukula, zomwe zimapangitsa kuti magazi ambiri asefedwe. Ma arterioles a efferent amanyamulanso magazi kuchokera ku glomerulus.
• Mapapu : Mapapu akamalephera kulandira mpweya wokwanira, ma arterioles amachepa. Izi zimapangitsa kuti magazi asunthidwe kuchoka m'malo omwe ali ndi mpweya wochepa ndikulunjika kumadera omwe ali ndi mpweya wochuluka.
• Ubongo: Ma arterioles mu ubongo amatha kukulirakulira, zomwe zimapangitsa kuti magazi aziyenda bwino kupita ku ubongo. Izi zimathandiza ubongo kulandira mpweya wabwino komanso zakudya zabwino.

Zinthu zodabwitsa zokhudza `(Arterioles)`!

Pali zinthu zodabwitsa kwambiri zokhudza "Arterioles" ang'onoang'ono awa.

Choyamba n’chakuti selo lililonse losalala la minofu mu arteriole lili ndi neuron yakeyake, kapena selo la mitsempha. Kawirikawiri, maselo angapo a mitsempha amasonkhana pamodzi kuti atumize zizindikiro ku maselo ambiri a minofu. Koma apa, selo lililonse la minofu limalandira uthenga mwachindunji!

Izi zikutanthauza kuti ngati mitsempha yathu yalandira chizindikiro choti ikule kapena kuchepetsa kukula kwa `(Arteriole)`, imatha kuchita izi mwachangu komanso molondola kwambiri. Izi zimathandiza kuwongolera kuthamanga kwa magazi ndi kuchuluka kwa magazi omwe akuyenda bwino kwambiri. Chinthu china chodabwitsa ndichakuti ngati kukula kwa `(Arteriole)` kwachepetsedwa kufika theka, ndiko kuti, ngati kwapindidwa pakati ndendende, kuchuluka kwa magazi omwe akuyenda mkati mwake kumachepa kufika pa gawo limodzi mwa khumi ndi zisanu ndi chimodzi (1/16)! Izi zikutanthauza kuti ngakhale kusintha pang'ono kwa dayamita kumakhudza kwambiri kuchuluka kwa magazi omwe akuyenda.

Kodi `(Arterioles)` amapangidwa ndi chiyani?

Ma Arterioles si machubu okha. Ndi njira zosinthasintha, zokhuthala zopangidwa ndi minofu. Ichi ndichifukwa chake amatha kusunga kuthamanga kwa magazi ndikulamulira kuchuluka kwa magazi omwe amayenda kudzera mwa iwo. Ndi minofu yambiri kuposa mitsempha. Izi zili choncho chifukwa amafunika kufinya ndikukula bwino kuti athe kupirira kuthamanga kwa magazi komwe mtima umapopa komanso kuwongolera kuyenda kwa magazi. Ma Arterioles ali ndi zigawo zitatu zazikulu: 1. Tunica intima: Iyi ndi gawo lamkati kwambiri. Lili ndi maselo a epithelial. Gawoli limalumikizana ndi gawo la minofu pakati. 2. Tunica media: Iyi ndi gawo lapakati. Lili ndi maselo osalala a minofu ndi minofu yotanuka. Ma arterioles amafinya ndikufalikira chifukwa cha gawoli. 3. Tunica adventitia: Iyi ndi gawo lakunja kwambiri. Lili ndi minofu yolumikizana, ulusi wa collagen, ndi malekezero a mitsempha.

Kodi ndi matenda ati omwe amakhudza `(Arterioles)`?

Ma arterioles ndi mitsempha yamagazi. Chifukwa chake, matenda omwe amakhudza dongosolo lathu la mtima amathanso kukhudza ma arterioles. Nazi zina mwa matenda otere:

• Kuthamanga kwa magazi : Kuthamanga kwa magazi nthawi zonse kumawononga ma arterioles.
• Kusuta : Kusuta kumawononga mkati mwa mitsempha yamagazi ndipo kumachepetsa kusinthasintha kwake.
• Cholesterol yambiri: Pamene kuchuluka kwa cholesterol m'magazi kukukwera, kumatha kusonkhana m'mitsempha yamagazi, zomwe zimapangitsa kuti mitsempha yamagazi ichepetse. Izi zimatchedwa atherosclerosis.
• Matenda Osatha a M'mapapo Oletsa Kutsekeka ( COPD ): Matendawa amatha kukhudza ma arterioles m'mapapo.
• Matenda otupa m'matumbo
• Kuundana kwa magazi `(Thrombosis)`
• Matenda a nyamakazi
• Matenda a cystic fibrosis
• Vasculitis: Izi zikutanthauza kutupa ndi kutupa kwa makoma a mitsempha yamagazi.
• Arteriolosclerosis: Mapuloteni omwe amaikidwa m'makoma a mitsempha yamagazi, makamaka m'ma arterioles a impso.
• Kukwapula pang'ono:Zingachitike chifukwa cha kutsekeka kwa "Arteriole" kapena "Aneurysms" (kuphulika kwa mtsempha wamagazi).
• Matenda a shuga otchedwa diabetes-related microangiopathy: Matenda a shuga amachititsa kuwonongeka kwa ma arterioles, omwe amasowa mpweya.

Chofunika kwambiri n’chakuti, makoma a ma arterioles akawonongeka, sangathe kugwedezeka kapena kukulirakulira bwino. Izi zimakhudza kwambiri kuthamanga kwa magazi ndi kuyenda kwa magazi.

Kodi zizindikiro zofala za matenda okhudzana ndi `(Arterioles)` ndi ziti?

Zina mwa zizindikiro za matenda omwe amakhudza ma arterioles ndi monga:

Vasculitis (kutupa kwa mitsempha yamagazi)

• Kuchepetsa thupi
• Malungo
• Kumva kutopa nthawi zambiri
• Ziphuphu pakhungu, monga ziphuphu ndi mabala

`(COPD)` (Matenda Osatha a M'mapapo Oletsa Kutsekeka)

• Kuvuta kupuma
• Kupuma movutikira
• Kutsokomola pafupipafupi

Magazi amaundana

• Kuvuta kupuma (ngati magazi oundana ali m'mapapo kapena mumtima)
• Kupweteka pachifuwa (ngati pali magazi oundana mumtima)
• Kuvutika kulankhula (ngati magazi ali ndi magazi oundana mu ubongo)
• Kutupa m'miyendo (magazi ambiri amayamba kuuma m'mitsempha ya miyendo)

Matenda otupa m'matumbo

• Kupweteka m'mimba
• Kutuluka magazi (ndi ndowe)
• Kutsegula m'mimba
• Kusanza ndi kusanza

Ngati muli ndi zizindikiro izi, ndikofunikira kwambiri kufunafuna upangiri wa dokotala.

Njira zowunikira thanzi la `(Arterioles)`

Dokotala wanu angagwiritse ntchito njira zosiyanasiyana zojambulira kuti aone thanzi la mitsempha yanu yamagazi. Zina mwa izi ndi izi:

• CT angiogram: Izi zitha kujambula zithunzi zatsatanetsatane za mitsempha yamagazi, kuphatikizapo ma arterioles.
• MR angiogram: Iyi ndi njira yowoneranso mitsempha yamagazi pogwiritsa ntchito mafunde a maginito.
• Doppler ultrasound: Izi zimatha kuona liwiro ndi kapangidwe ka magazi kudzera m'mitsempha yamagazi.

Mayeso awa amatha kuzindikira kutsekeka kulikonse kapena kuwonongeka kwa ma arterioles.

Kodi mankhwala a `(Arterioles)` ndi otani?

Dokotala wanu angakulembereni mankhwala othandiza kuti mtima wanu ugwire bwino ntchito - kuphatikizapo mitsempha yanu yamagazi - kuphatikizapo mitsempha yamagazi.

• Mankhwala oletsa kuthamanga kwa magazi.
• Mankhwala ochepetsa cholesterol.
• Mankhwala ochepetsa kutupa (monga matenda monga "Vasculitis").
• Kusiya kusuta fodya ndi njira yofunika kwambiri yothandizira komanso yopewera matenda.

Malangizo Osavuta Okhala ndi Moyo Wathanzi wa Arteriolar System

Mukhoza kusunga ma `(Arterioles)` anu athanzi mwa kutsatira zizolowezi zosavuta izi:

• Chepetsani kuchuluka kwa mchere womwe mumadya.
• Chepetsani zakudya zokhala ndi mafuta ambiri okhuta.(Zinthu monga mafuta, zakudya zokazinga, nyama yonenepa)
• Kuchita masewera olimbitsa thupi nthawi zonse. Kuyenda kwa mphindi zosachepera 30 patsiku ndikwabwinonso.
• Musagwiritse ntchito zinthu zosuta fodya. Siyani kusuta fodya kotheratu.
• Khalani ndi kulemera koyenera komwe kungakuyenerereni.

Pomaliza, zinthu zoti muzikumbukira

Kotero, tsopano mukumvetsa kufunika kwa ma `(Arterioles)` ang'onoang'ono, osaoneka awa ndi ofunika kwambiri m'thupi lathu. Ndiwo omwe amasamalira kuyenda kwa magazi ndi kuthamanga kwa magazi m'thupi lathu. Sitingaganizire kwambiri za iwo, koma amachita ntchito yabwino mwakachetechete.

Mukadya zakudya zopatsa thanzi, kuchita masewera olimbitsa thupi nthawi zonse, komanso kukhala ndi moyo wabwino, mutha kusunga dongosolo lanu lonse la mtima, kuphatikizapo "Arterioles," lomwe ndi labwino.

Matenda ena a mtima ndi mitsempha yamagazi sangakhale ndi zizindikiro zilizonse kumayambiriro. Chifukwa chake, ndikofunikira kwambiri kupita kuchipatala nthawi zonse. Kenako, ngati pali vuto lililonse, likhoza kuzindikirika lisanakhale vuto lalikulu. Samalirani '(Arterioles)' yanu, adzakusamalirani bwino!
