Kodi ma valve a mtima ndi chiyani? Tiyeni tikambirane mwachidule!

Mtima wanu uli ngati injini yodabwitsa yomwe imagwira ntchito mosalekeza. Ntchito yayikulu ya injini iyi ndikupopera magazi m'thupi lanu lonse. Tangoganizani, kuti ntchitoyi ichitike bwino, magazi ayenera kuyenda mbali imodzi, ndendende. Sangayende chammbuyo. Kuti ntchitoyo ichitike bwino, pali dongosolo labwino kwambiri la zipata mkati mwa mtima. Mu zamankhwala, timatcha zipata izi kuti ma valve a mtima . Lero tikulankhula za ma valve ang'onoang'ono awa, koma ofunikira kwambiri pa moyo wanu.

Kodi ma valve a mumtima amagwira ntchito bwanji? Ndi njira yodabwitsa bwanji!

Kuti timvetse izi, choyamba tiyeni tione mwachidule Aufbau, kapena kapangidwe ka mtima. Mtima wanu uli ngati nyumba yokhala ndi zipinda zinayi. Pali zipinda ziwiri pamwamba ndi ziwiri pansi. Timazitcha Atria ndi Ventricles.

• Chipinda chapamwamba kumanja: Atrium Yakumanja
• Chipinda chapansi kumanja: Ventricle Yamanja
• Chipinda chapamwamba kumanzere: Atrium Yakumanzere
• Chipinda chapansi kumanzere: Kumanzere kwa Ventricle

Tsopano, pakati pa zipinda izi, ndi pakati pa mitsempha ikuluikulu yamagazi yomwe imanyamula magazi kuchokera m'zipinda, pali ma valve, kapena zipata zinayi. Izi zimapangidwa ndi minofu yopyapyala koma yolimba kwambiri. Timatchanso timabukuti kapena cusps.

Tangoganizirani momwe dontho la magazi limayendera m'thupi lanu.

1. Choyamba, magazi omwe agwiritsidwa ntchito m'thupi ndipo alibe mpweya wokwanira (tiwatche kuti magazi abuluu kuti timvetsetse mosavuta), amachokera m'thupi lonse ndipo amasonkhana m'chipinda chapamwamba kumanja, ndiko kuti, atrium yakumanja .

2. Kenako, valavu yoyamba, valavu ya tricuspid, imatsegulidwa. Kenako, magazi omwe ali m'chipinda chapamwamba amalowa m'chipinda chapansi, ventricle yakumanja . Magazi akalowa, valavu iyi imatseka mwamphamvu, osalola magazi kuti abwerere mmwamba.

3. Tsopano ventricle yakumanja imakoka mwamphamvu, kutanthauza kuti imapopa, ndikukankhira magazi opanda mpweya kudzera mu valavu yachiwiri. Imeneyo ndi valavu ya m'mapapo . Magazi awa amapita mwachindunji ku mapapo. Chifukwa chiyani? Kuti apeze mpweya.

4. M'mapapo, magazi awa amakhala ndi mpweya wabwino . Tsopano magazi awa ndi atsopano, ofiira okhala ndi mpweya. Magazi awa amabwerera kumtima. Koma nthawi ino amabwera kumanzere.

5. Magazi olemera mpweya amenewa amasonkhana m'chipinda chapamwamba kumanzere, ndiko kuti, atrium yakumanzere .

6. Kenako, valavu yachitatu, valavu ya mitral, imatsegulidwa. Kenako, magazi okhala ndi mpweya wochuluka kuchokera ku chipinda chapamwamba amalowa mu chipinda chapansi, ventricle yakumanzere . Ichi ndi chipinda champhamvu kwambiri mumtima.

7. Pomaliza, ventricle yakumanzere imapopa mwamphamvu kwambiri. Kenako valavu yachinayi komanso yofunika kwambiri, valavu ya aortic, imatsegulidwa.Akatsegula, magazi odzaza ndi mpweya amapopedwa mu aorta, mtsempha waukulu kwambiri wamagazi m'thupi. Kuchokera pamenepo, magazi amafalikira m'thupi lonse, kuyambira mutu mpaka kumapazi.

Phokoso la "lub-dub" lomwe mumamva mumtima mwanu kwenikweni ndi phokoso la ma valve anayi awa omwe akutseguka ndi kutsekedwa motsatizana. Kodi sizodabwitsa?

Ma valve anayi mumtima ndi zomwe amachita

Tiyeni tsopano tiwone ma valve anayi awa mwatsatanetsatane. Iliyonse ya iwo ili ndi malo ake, mawonekedwe ake, ndi ntchito yake yapadera.

Ndi matenda ati omwe angakhudze ma valve a mtima?

Nthawi zina ma valve amenewa sagwira ntchito bwino. Izi zikutanthauza kuti mtima uyenera kugwira ntchito molimbika kuposa masiku onse kuti upompe magazi omwe thupi limafunikira. Pakapita nthawi, mtima ukhoza kutopa.

Pali zifukwa zingapo zomwe zimachititsa kuti mavuto a valve achitike:

• Ukalamba: Pamene tikukalamba, ma valve amenewa, monga ziwalo zina za thupi, amatha kusintha.
• Matenda a mtima obadwa nawo: Anthu ena amabadwa ndi zolakwika zina za valve (mwachitsanzo, kuchepa/kuwonjezeka kwa chiwerengero cha valve, kusintha kwa mawonekedwe awo). Timatcha izi (matenda a mtima obadwa nawo) .
• Matenda: Matenda ena a bakiteriya amatha kuwononga mwachindunji ma valve a mtima.
• Matenda ena: Matenda monga matenda a shuga, kuthamanga kwa magazi, ndi matenda ena a mtima amathanso kuwononga ma valve.

Pali mitundu itatu ikuluikulu ya mavuto a valavu omwe angakhudze valavu iliyonse.

Kodi mungadziwe bwanji ngati pali vuto ndi valavu? Zizindikiro zake ndi ziti?

Chodabwitsa n'chakuti anthu ena akhoza kukhala ndi vuto ndi imodzi mwa ma valve awo a mtima koma osawonetsa zizindikiro zilizonse . Popeza matenda a ma valve amakula pakapita nthawi, zizindikiro zimayamba kuonekera akamakula.

Kawirikawiri, dokotala wanu ndiye woyamba kuzindikira vuto la valavu. Chizindikiro choyamba ndi phokoso lachilendo lomwe amamva akaika stethoscope pachifuwa panu, lotchedwa heart murmur . Komabe, kumva kulira kwa mtima sikutanthauza nthawi zonse kuti pali vuto. Nthawi zina, pamakhala "kulira kwa mtima kosalakwa" komwe sikuli koopsa.

Komabe, ngati zizindikiro zotsatirazi zikupezeka, vuto likhoza kukhala valavu:

• Kupweteka pachifuwa: Kupweteka komwe kumamveka ngati kulimba kapena kutsekeka pachifuwa.
• Chizungulire ndi kukomoka: Kumva mwadzidzidzi kuzungulira kapena kutaya chidziwitso.
• Kutopa: Kumva kutopa kwambiri, kusakhala ndi moyo, ngakhale osagwira ntchito iliyonse.
• Kugunda kwa mtima: Kumva ngati mtima wako ukugunda mofulumira ndipo chifuwa chako chikugwedezeka.
• Kupuma movutikira: Kuvutika kupuma, makamaka pochita masewera olimbitsa thupi, kuyenda mtunda waufupi, kukwera masitepe, kapena kugona pabedi.
• Kutupa: Kutupa m'makolo, mapazi, miyendo, kapena nthawi zina m'mimba.

Kodi mungatani kuti mtima ukhale wathanzi ndi matenda a valavu?

Ngati dokotala wanu atsimikiza kuti muli ndi matenda a mtima, pali zinthu zambiri zomwe mungachite kuti mukhale ndi moyo wathanzi.

• Pewani kusuta fodya kotheratu. Kusuta fodya ndi mdani wamkulu wa mtima.
• Yesani kuthamanga kwa magazi ndi kuchuluka kwa mafuta m'thupi nthawi zonse ndipo muziyang'anira bwino. Imwani mankhwala omwe dokotala wanu wakupatsani.
• Khalani ndi zakudya zabwino pa mtima . Chepetsani zakudya zokhala ndi mafuta ambiri, mchere, ndi shuga. Phatikizani ndiwo zamasamba, zipatso, masamba obiriwira, ndi nsomba zazing'ono muzakudya zanu.
• Kuchita masewera olimbitsa thupi nthawi zonse.Komabe, ndikofunikira kwambiri kufunsa dokotala wanu masewera olimbitsa thupi omwe akuyenererani.
• Pitani kwa dokotala nthawi zonse kuti akakupimeni. Iye akhoza kuyang'anira vuto la mtima wanu ndikukupatsani malangizo ofunikira.
• Musanayambe chithandizo cha mano kapena opaleshoni ina, dokotala wanu angakulangizeni kuti mumwe mankhwala opha tizilombo toyambitsa matenda . Chifukwa cha izi ndi chakuti mabakiteriya omwe amalowa m'thupi nthawi imeneyi amatha kuwononga ma valve ofooka.
• Musaiwale kuuza madokotala onse omwe akukuthandizani, kuphatikizapo dokotala wa mano, kuti muli ndi vuto la valavu ya mtima.

Nthawi iliyonse mukafuna kuonana ndi dokotala

Ngati muli ndi vuto la valavu ya mtima, muyenera kusamala kwambiri ndi matenda a mtima (endocarditis) . Chifukwa chake, ngati muli ndi zizindikiro za matenda monga malungo, kupweteka kwa thupi, ndi kupweteka pakhosi, imbani dokotala nthawi yomweyo. Musangoganiza kuti ndi chimfine wamba.
