Kodi munayamba mwadzifunsapo momwe magazi amayendera m'thupi lanu lonse komanso momwe amasungira kuthamanga kwa magazi kosalekeza? Tili ndi mtundu wa mtsempha wamagazi m'thupi mwathu womwe ndi waung'ono kwambiri kotero kuti sungawonekere ndi maso, koma wamphamvu kwambiri. Lero tikulankhula za ngwazi zazing'ono izi, Arterioles.
Mwachidule, kodi ma arterioles awa ndi chiyani?
Ma arterioles ndi mitsempha yaing'ono kwambiri, yopyapyala. Ali ngati nthambi zomwe zimatuluka m'mitsempha ikuluikulu yamagazi m'thupi lathu, mitsempha. Taganizirani kuti ndi misewu yaying'ono yam'mbali yomwe imatuluka m'misewu ikuluikulu n'kupita m'nyumba. Ma arterioles awa ndi omwe amanyamula magazi kuchokera mumtima kupita ku minofu ndi ziwalo za thupi lathu.
Ma arterioles awa amalumikizana ndi mitsempha yaing'ono yamagazi. Timawatcha kuti ma capillaries. Ma capillaries ndi mitsempha yopyapyala kwambiri yamagazi, monga ulusi wa ukonde wa kangaude. Apa ndi pomwe zinthu zofunika kwambiri zimachitika. Ali ngati malo osinthirana. Magazi amapereka mpweya ndi michere ku minofu, ndipo minofuyo imatenga zinyalala monga carbon dioxide kubwerera m'magazi. Pambuyo pa kusinthana kumeneku, mitsempha yaying'ono (ma venules) imalumikizana ndi mitsempha iyi kuti inyamule magazi odzaza ndi zinyalala kubwerera kumtima.
Kotero, ma arterioles ndi mgwirizano wofunikira kwambiri pakati pa mitsempha yamagazi ndi mitsempha yamagazi.
Kodi ntchito yaikulu ya ma arterioles ang'onoang'ono awa ndi yotani?
Ngakhale kuti izi ndi zazing'ono, zimathandiza kwambiri pakulamulira kuyenda kwa magazi ndi kuthamanga kwa magazi m'thupi lathu.
- Kuthamanga kwa magazi ndi kuwongolera kuyenda kwa magazi: 80% ya kukana kwa kuyenda kwa magazi m'thupi lathu kumayendetsedwa ndi ma arterioles awa. Mwachidule, mitsempha yaying'ono yamagazi iyi imatsimikizira momwe magazi amathamangira mwachangu, molimbika, komanso kuchuluka kwa magazi komwe amapopedwa kupita ku chiwalo chilichonse. Izi zimachitika mwa kukokana ndikumasula minofu yomwe ili m'makoma awo. Zili ngati kukanikiza chitoliro chamadzi kuti chiwongolere kuyenda kwa madzi. Umu ndi momwe kuthamanga kwa magazi athu kumasungidwira pamlingo wokhazikika.
- Kuthandiza pakusinthana kwa magazi: Monga tanenera kale, mitsempha imagwira ntchito ngati "mkhalapakati" pakati pa mitsempha ikuluikulu ndi mitsempha yaying'ono kwambiri, ikugwira ntchito ngati mlatho wosinthirana mpweya, zakudya, ndi zinyalala.
Kodi ma arterioles amathandiza bwanji ziwalo zina?
Ma arterioles amapezeka m'thupi lathu lonse, ndipo amathandiza pafupifupi chiwalo chilichonse. Nazi zitsanzo zina.
| Chiwalo | Momwe Ma Arterioles Amathandizira |
|---|---|
| Khungu | Tikamva kuzizira, mitsempha yamagazi iyi imapindika ndikusunga magazi mkati mwa thupi. Izi zimatenthetsa thupi. Tikamva kutentha, imatambasuka ndikutumiza magazi ambiri pakhungu, zomwe zimatulutsa kutentha m'thupi. |
| Impso | Pali mitundu iwiri ya ma arterioles omwe amabweretsa magazi kupita ndi kuchokera ku glomerulus mu impso. Mitundu iyi imatambasuka ndi kufupika, kulamulira liwiro lomwe magazi amasefedwa ndi impso. |
| Mapapu | Ma arterioles amenewa amachepa kuti achepetse kuyenda kwa magazi kupita kumadera a m'mapapo omwe ali ndi mpweya wochepa ndikutumiza magazi kumadera omwe ali ndi mpweya wochuluka. Izi zimathandiza kuti mpweya wambiri womwe umalowa m'magazi ukhale wambiri. |
| Ubongo | Ubongo ukafuna magazi ambiri, ma arterioles amakula, zomwe zimapangitsa kuti magazi ambiri ayende. |
Ndi matenda ati omwe amakhudza ma arterioles?
Popeza ma arterioles nawonso ndi mitsempha yamagazi, matenda aliwonse omwe amakhudza mtima ndi kayendedwe ka magazi amathanso kuwakhudza.
| Matenda | Kufotokozera kosavuta |
|---|---|
| Kuthamanga kwa magazi (BP) | Kuthamanga kwa magazi kwa nthawi yayitali. |
| Kusuta | Mankhwala omwe ali mu utsi amawononga mitsempha yamagazi. |
| Cholesterol yambiri | Kuyika mafuta m'mitsempha yamagazi. |
| Kuchuluka kwa atherosclerosis | Makoma a mitsempha yamagazi amakhala olimba komanso okhuthala. |
| Vasculitis | Kutupa/kutupa kwa makoma a mitsempha yamagazi. |
| Kuundana kwa magazi (Thrombosis) | Magazi amaundana mkati mwa mitsempha ya magazi. |
| Matenda a shuga | Shuga wambiri ungawononge mitsempha yamagazi ing'onoing'ono. |
Matendawa amawononga makoma a mitsempha yamagazi, zomwe zimapangitsa kuti isathe kugwira kapena kukulitsa bwino. Izi zimakhudza kuthamanga kwa magazi komanso kuyenda kwa magazi.
Kodi mungadziwe bwanji ngati pali vuto? - Zizindikiro
Zizindikiro za matenda omwe amakhudza ma arterioles zimasiyana malinga ndi matendawa. Nazi zitsanzo zodziwika bwino.
| Udindo | Zizindikiro zooneka |
|---|---|
| Vasculitis (kutupa kwa mitsempha yamagazi) | Kuchepetsa thupi, kutentha thupi, kutopa, ziphuphu pakhungu ndi mabala. |
| Magazi amaundana | Ngati chili m'mapapo, chimavuta kupuma, ngati chili mumtima, ndi kupweteka pachifuwa, ngati chili muubongo, ndi vuto kulankhula, ngati chili m'miyendo, chikutupa m'miyendo. |
| Matenda a m'mapapo (COPD) | Kuvuta kupuma, kupuma movutikira, kukhosomola pafupipafupi. |
Chithandizo ndi njira zokhalira ndi thanzi labwino
Dokotala wanu adzakupatsani chithandizo ndi upangiri kuti dongosolo lanu lonse la mtima, kuphatikizapo mitsempha yanu yamagazi, likhale lathanzi.
| Mankhwala Ochiritsira | Zinthu zomwe mungachite nokha (Kusintha kwa Moyo) |
|---|---|
| Mankhwala oletsa kuthamanga kwa magazi. | Kuchepetsa mchere kuchokera muzakudya. |
| Mankhwala ochepetsa mafuta m'thupi. | Kuchepetsa zakudya zokhala ndi mafuta ambiri (mafuta, zakudya zokazinga, nyama yokazinga). |
| Mankhwala oletsa kutupa kwa matenda monga vasculitis. | Kuchita masewera olimbitsa thupi nthawi zonse. |
| Malangizo oti musiye kusuta fodya. | Kupewa kwathunthu fodya. |
| Kusunga kulemera koyenera komwe kungakuyenerereni. |
Sitingaganizire kwambiri za ma arterioles ang'onoang'ono komanso ogwira ntchito molimbika awa m'miyoyo yathu ya tsiku ndi tsiku, koma ndi ofunikira kwambiri pakulamulira kuyenda kwa magazi ndi kuthamanga kwa magazi. Zakudya zabwino komanso kuchita masewera olimbitsa thupi nthawi zonse kungathandize kuti dongosolo lanu lonse la mtima likhale bwino. Popeza matenda ena sasonyeza zizindikiro zilizonse kumayambiriro, ndikofunikira kuonana ndi dokotala wanu kuti akakuwoneni nthawi zonse . Mwanjira imeneyi, mutha kupeza vuto laling'ono lisanakhale lalikulu.
Uthenga Wopita Nawo Kunyumba
- Ma arterioles ndi mtundu wa mtsempha wamagazi waung'ono kwambiri koma wamphamvu kwambiri womwe umalamulira kuthamanga kwa magazi ndi kuyenda kwa magazi m'thupi lathu.
- Zizolowezi za moyo monga chakudya chomwe mumadya, kuchita masewera olimbitsa thupi, komanso kupewa kusuta fodya zimakhudza kwambiri thanzi la mitsempha yamagazi iyi.
- Popeza matenda ena sasonyeza zizindikiro kumayambiriro, ndikofunikira kwambiri kupita kuchipatala nthawi zonse.
- Ngati muli ndi nkhawa kapena kukayikira kulikonse pa thanzi lanu, musazengereze kulankhula ndi dokotala wanu za vutoli.
