Tiyeni tiphunzire za momwe magazi amayendera m'thupi lathu? (Njira Yoyendera Magazi)

Kodi mukudziwa kuti pali dongosolo lodabwitsa mkati mwa thupi lanu lomwe limagwira ntchito nthawi zonse, kaya mukugona, mukugwira ntchito, kapena mukusewera? Ndi dongosolo lozungulira magazi, lomwe limapereka moyo ku matupi athu ndikunyamula magazi m'thupi lonse. Monga dongosolo la mapaipi amadzi lomwe limapereka madzi mumzinda, limapereka michere ku selo iliyonse m'thupi lathu ndikuchotsa zinyalala. Tiyeni tikambirane izi mwachidule.

Kodi dongosolo la magazi m'thupi limeneli ndi chiyani?

Mwachidule, dongosolo lozungulira magazi ndi dongosolo lopangidwa ndi mtima wanu ndi mitsempha yamagazi . Anthu ena amalitchanso dongosolo la mtima. Mayina onsewa amatanthauza dongosolo lomwelo.

Ntchito yake yayikulu ndikugwiritsa ntchito magazi kupereka zakudya ku maselo mabiliyoni ambiri m'thupi lathu ndikuchotsa zinyalala m'maselo amenewo. Mwanjira ina, zili ngati njira yoyendera m'thupi lathu. Mtima wanu umagwira ntchito ngati pampu yayikulu, kupompa magazi m'thupi lonse kudzera mu netiweki iyi ya mitsempha yamagazi. Magazi awa amapereka mpweya ndi michere m'minofu yathu, minofu, ndi ziwalo zathu. Amanyamulanso zinyalala, monga carbon dioxide , zomwe zimapangidwa m'ziwalo izi ndikuzipereka ku ziwalo zomwe zingazichotse m'thupi.

Kodi ntchito zazikulu za dongosololi ndi ziti?

Pali ntchito zitatu zazikulu zomwe zimachitika ndi dongosololi.

• Kupompa magazi m'thupi lonse: Mtima wathu ukugunda usana ndi usiku, ngakhale titagona, ndipo umagwira ntchito imeneyi.
• Kupereka zofunika: Kupereka mpweya ndi zakudya ku ziwalo zathu, minofu, ndi minofu.
• Kuchotsa zinthu zosafunikira: Kusonkhanitsa ndi kuchotsa zinyalala monga carbon dioxide m'thupi.

Taganizirani ngati ulendo wosatha. Magazi, omwe amayamba mumtima, amayenda kudzera m'mitsempha ikuluikulu yamagazi (mitsempha) kupita ku ziwalo zathu. Kumeneko, pali netiweki ya mitsempha yamagazi yabwino kwambiri, yotchedwa capillaries, yomwe imapereka mpweya ndi michere ku maselo ndikusonkhanitsa zinyalala kuchokera ku maselo amenewo. Kenako, magazi okhala ndi zinyalalazo amabwerera kumtima kudzera mumtundu wina wa mitsempha yamagazi (mitsempha). Kuchokera mumtima, magazi amatumizidwa ku mapapo, komwe amabwezeretsedwa mpweya ndikubwerera kumtima, kuyambitsa ulendo watsopano. Izi zimachitika sekondi iliyonse yomwe mtima wanu ukugunda.

Dongosololi limapereka patsogolo kwambiri kupereka magazi ku ubongo ndi mtima wa thupi lathu. Chifukwa ngati magazi a mu ubongo asiya, mutha kutaya chikumbumtima pasanathe masekondi. Ngati magazi asiya kuyenda kwa mphindi zoposa zinayi, ubongo ukhoza kuwonongeka. Mofananamo, ngati mtima sulandira magazi omwe ukufunikira, sungathe kugwira ntchito yake yopompa bwino.

Kodi dongosolo la magazi limeneli limagwira ntchito bwanji?

Zonsezi zimachitika ndi mtima, mapapo, ndi mitsempha yamagazi kugwirira ntchito limodzi. Tiyeni tiwone momwe izi zimachitikira pang'onopang'ono.

1. Choyamba, ventricle yakumanja ya mtima wanu imapopera magazi opanda mpweya kupita ku mapapo anu. Magazi awa amayenda kudzera mu mtsempha waukulu wa m'mapapo, womwe ndi Pulmonary Artery.

2. Mkati mwa mapapo, mpweya wa carbon dioxide womwe uli m'magazi awa umatuluka ndipo umalowedwa m'malo ndi mpweya wochokera mumpweya umene timapuma.

3. Magazi awa, omwe tsopano ali odzaza ndi mpweya, amabwerera ku atrium yakumanzere ya mtima kudzera m'mitsempha ya m'mapapo.

4. Kuchokera ku atrium yakumanzere, magazi olemera mpweya amatumizidwa ku ventricle yakumanzere, yomwe ndi gawo lalikulu komanso lamphamvu kwambiri la mtima.

5. Mtsempha wa kumanzere umakoka mwamphamvu ndipo umapopera magazi odzaza ndi mpweya m'mitsempha kuti uwafalitse m'thupi lonse.

6. Mwanjira imeneyi, magazi omwe amazungulira thupi lonse amapereka mpweya ndi zakudya ku ziwalo ndi minofu, ndikusonkhanitsa zinyalala zomwe zili mmenemo.

7. Magazi awa (magazi opanda mpweya) omwe asonkhanitsa zinyalala ndi carbon dioxide amabwerera kumtima kudzera m'mitsempha.

8. Mtima umapompa magaziwa kubwerera m'mapapo kuti awadzaze ndi mpweya. Tikapuma, mpweya wa carbon dioxide umatulutsidwa.

Kuzungulira kumeneku ndi komwe kumachitika nthawi zonse. Njira yopita kwa magazi m'mapapo ndikutenga mpweya ndikubwerera kumtima imatchedwa pulmonary circulation . Mofananamo, njira yonyamulira magazi okhala ndi mpweya kuchokera mumtima kupita ku thupi lonse imatchedwa systemic circulation .

Kodi ziwalo zazikulu za dongosolo lozungulira magazi ndi ziti?

Monga tanenera kale, pali magawo anayi akuluakulu a dongosololi. Chilichonse chili ndi ntchito yakeyake. Kuti timvetse bwino izi, tiyeni tiwone tebulo ili.

Kodi ndi matenda ati omwe amakhudza dongosololi?

Mavuto ambiri m'thupi lathu la magazi amakhudzana ndi kutsekeka kapena kuchepa kwa ntchito ya mitsempha yamagazi. Mitsempha yamagazi ndi yomwe imapereka mpweya m'thupi lonse, kotero ngati pali kutsekeka kulikonse, mpweya umenewo umasokonekera.

Pansipa pali zinthu zina zomwe zimakhudza dongosololi.

• Kuthamanga kwa magazi : Kuthamanga kwa magazi kumawonjezeka pa makoma a mitsempha yamagazi pamene magazi akuyenda m'mitsemphamo.
• Cholesterol yambiri: Mafuta ambiri m'magazi amatha kusungidwa m'mitsempha yamagazi ndikuyitseka.
• Kusakhazikika kwa kugunda kwa mtima (Arrhythmia):Kugunda kwa mtima kosakhazikika kapena kayimbidwe kake.
• Matenda a mtima: Kuwonongeka kwa minofu ya mtima chifukwa cha kutsekeka kwa mtsempha wamagazi womwe umapatsa magazi kumtima.
• Mavuto a ma valve a mtima: Ma valve a mtima sakugwira ntchito bwino.
• Kulephera kwa mtima: Minofu ya mtima imafooka ndipo singathe kupopera magazi okwanira kupita ku thupi.
• Aneurysm: Kufooka kwa khoma la mtsempha wamagazi, zomwe zimapangitsa kuti lizitupa ngati baluni. Izi zimachitika kwambiri mu ubongo kapena mtsempha wamagazi.
• Stroke: Kutsekeka kapena kuphulika kwa mtsempha wamagazi womwe umapereka magazi ku ubongo.
• Atherosclerosis: Kuchepa kwa mitsempha yamagazi chifukwa cha kuyika kwa cholesterol ndi zinthu zina m'makoma a mitsempha.
• Matenda a mitsempha yamagazi: Matenda monga thrombosis ya mitsempha yakuya.

Kodi tingatani kuti magazi athu aziyenda bwino?

Pali zinthu zambiri zomwe mungachite kuti mtima wanu ndi mitsempha yamagazi yanu zikhale zathanzi. Izi ndi zinthu zosavuta zomwe mungawonjezere pa moyo wanu.

• Yesetsani kuchita masewera olimbitsa thupi nthawi zonse. Yesetsani kuchita masewera olimbitsa thupi kwa mphindi zosachepera 150 pa sabata. Kuyenda mwachangu, kuthamanga, kapena kukwera njinga ndi njira zabwino.
• Gonani bwino. Ndikofunikira kwambiri kugona mokwanira usiku uliwonse.
• Lamulirani kuthamanga kwa magazi. Ngati muli ndi kuthamanga kwa magazi, tsatirani malangizo a dokotala wanu komanso mankhwala anu molondola.
• Yang'anirani kuchuluka kwa cholesterol m'thupi lanu. Yang'anirani kuchuluka kwa cholesterol m'thupi lanu mwa kuchepetsa zakudya zokhala ndi mafuta ambiri.
• Pewani fodya kotheratu. Kusuta fodya kumawononga kwambiri mtima ndi mitsempha yamagazi.
• Idyani zakudya zopatsa thanzi pamtima. Idyani ulusi wambiri, ndiwo zamasamba, ndi zipatso. Chepetsani zakudya zokhala ndi mafuta ambiri.
• Khalani ndi kulemera kwabwino. Kusunga kulemera kwabwino malinga ndi kutalika kwanu n'kofunika kwambiri.
• Yang'anirani kuchuluka kwa shuga m'magazi mwanu. Ngati muli ndi matenda a shuga, yang'anirani bwino.
• Kuchepetsa nkhawa. Mutha kuchepetsa nkhawa pochita zinthu monga kusinkhasinkha, yoga, ndi zosangalatsa.

Kodi pali mitundu iwiri ya magazi, magazi ofiira ndi magazi abuluu?

Ayi. Dontho lililonse la magazi m'thupi lathu ndi lofiira.Magazi amapeza mtundu wofiira kuchokera ku puloteni yotchedwa hemoglobin m'maselo ofiira a magazi. Koma magazi okhala ndi mpweya ndi ofiira kwambiri, pomwe magazi opanda mpweya ndi ofiira owala komanso ofiirira. Mitsempha yomwe ili pansi pa khungu lathu imaoneka yabuluu chifukwa cha momwe kuwala kumayendera m'magawo a khungu. Koma mkati mwa mitsempha imeneyo muli magazi ofiira.

Kodi mitsempha yamagazi nthawi zonse imanyamula magazi okhala ndi mpweya?

Nthawi zambiri, inde. Koma pali chinthu chimodzi chapadera. Ndicho Mtsempha wa M'mapapo . Umanyamula magazi opanda mpweya kuchokera mumtima kupita m'mapapo. Mofananamo, Mtsempha wa M'mapapo umanyamula magazi okhala ndi mpweya wochokera m'mapapo kupita kumtima. Iyi ndi nkhani yapadera pomwe njirayi imapita mosiyana.
