Mtima - Nchiyani ichi? ndi mtima wa munthu n'chiyani?

Mtima - ndi thupi waukulu wa munthu. Ndi mpope uwu mapampu magazi mu ziwiya. Malingana ngati mtima wanga ukugunda - munthu amakhala. Koma pamene tidzawukitsidwe kwa agwire ntchito zake zofunika - moyo adzaleka.

mpope mfundo

Akatswiri ofufuza wasonyeza kuti aliyense wa ulusi striated minofu - mtundu wa "mtima zotumphukira". kuchepetsa awo yotithandiza Kukwezeleza magazi. Ndi chifukwa chake zolimbitsa thupi zimapangitsa ntchito mtima zosavuta, koma chifukwa chilichonse ayenera M'malo mwake, kugwira ntchito mode mwadzidzidzi. Mwa njira, ichi ndi chimodzi mwa zinthu ambiri siudzalandilidwa ngathi lamulo ntchito zake zazikulu. Monga amadziwika, magazi akulowa capillaries (komwe kwambiri otsika kuthamanga) kwa msempha (kumene, Tikawonetsetsa mkulu). Kodi kusunga muyezo? Mtima - dongosolo lonse, ndipo mukhoza kunena, ndi changwiro. Chikhalidwe cha zonse ndinaganiza, ichi ndi muyezo anakhalabe chifukwa chakuti magazi kulowa capillaries kwa msempha umadutsa ziwiya magazi, ndipo kuumiriza anzawo nthawi ndi amachepetsa. Kenako amapita ku venules, ndi mwa iwo kale mu mitsempha.

mkombero mtima

Mtima - chiwalo kuti amachita ntchito yaikulu. Ndi mndandanda wa njira zosiyanasiyana amuzolengedwa, makina ndipo ngakhale magetsi. Zonse izi zikuchitika mwa mkombero umodzi yosangalala ndi chidule, ndi chifukwa tsiku lawo pa anachita ambiri. Asayansi amati mtima anthu wakhazikika pa maola 16, maola 24 ndipo 8 - yafupika. Tikumbukenso chidwi kuwirikiza kawiri wina chidwi. anthu ochepa mukudziwa kuti msinkhu, chiwerengero cha mabala amene anapanga mtima yafupika. Ndiko kuti, pafupipafupi amachepetsa. Mtima wa munthu, amene zaka kuposa zaka 60, yafupika nthaŵi 80 pa mphindi. Koma 125 kumenyedwa / mphindi - muyeso wa mwana wazaka. Pa moyo, galimoto yathu yaikulu yafupika biliyoni 3.1 - Munthu akhoza kungowauzira kuganiza za izo, monga chithunzi kwambiri! Ndipo potsiriza, mmodzi kwambiri chodabwitsa zoona. Mtima - ndi thupi yomwe lonse miyoyo yathu pa 250 miliyoni malita a magazi! Icho chimagwira ntchito kwenikweni chachikulu. Choncho muyenera kusamalira thanzi lawo, ndipo makamaka - kuti mtima, nthawi zonse kupereka ndi mavitamini ndi mchere.

Mtima mantha System

Thupi la munthu - ndi imodzi yothandizira mitsempha. Ndipo mitima yawo ndi kuchita ambirimbiri. Ngakhale kuti innervation limba amachokera ku thunthu wachifundo komanso mitsempha vagus, komabe ali ndi chilangizo kwenikweni. Malemeredwe akupezeka malangizo kuchokera pamwamba mpaka mfundo pansi mu septum interatrial. chizindikiro Izi ndiye ankadutsa otchedwa atrioventricular mfundo (ndi kumalire a atria ndi ventricles). Ndipo komaliza "mfundo" - ziri ventricles. Mbendera chimakwirira onse a thupi lake.

mtima ndi wotani?

Real mtima, ndi chithunzi chimene ziribe kanthu kochita ndi fano limene limapezeka mu ulaliki wa munthu aliyense pa kutchulidwa kwa maonekedwe ake ngati phirilo zooneka thupi ndi mitsempha pafupi ndi mitengo ikuluikulu venous. Ngati kufotokoza mwa mawu, izo akufanana pang'ono priplyuschennoe dzira ndi m'mphepete pang'ono wakuthwa pansi ndi dongosolo ziwiya lalikulu pamwamba. Ngati ife kulankhula za akalumikidzidwa ndi makulidwe, apa tisaiwale kuti ali osiyana munthu aliyense. Izo zimatengera thupi, kugonana, msinkhu ndi thanzi. Lili mtima pakati pa chifuwa, koma uli chifupi ndi kumanzere. Izi zidalira pa makhalidwe munthu wa thupi; pakuti ena yapadera kwambiri, ena - si choncho. Mumadziwika ndi milandu matenda imene mtima wa lili kumanja. Komabe, galasi ili makonzedwe a matupi ndi anthu ziwalo n'zochepa.

Kapangidwe ka thupi

Choncho, kodi mtima, zikuonekeratu, ndi chimene chimaoneka - kwambiri. Koma si zinthu zonse muyenera kudziwa za thupi ili. Tiyeneranso kudziwa za mfundo za icho chiri. Choncho, mtima - chiwalo dzenje, koma pali ochuluka monga anayi mphako, akuchita ikukoka ntchito. atria awiri ndi ventricles awiri - ndiwo Gawo la izo. Wachiwiri awa - kwambiri yaikulu. Palpitations basi minofu awo misa, kapena kukhala enieni kwambiri, ndi thandizo la ventricle kumanzere. Mwa njira, ndi atria, iwo ogwirizana ndi mabowo limene linaperekedwa ndi valavu. ndi udindo wa chigawo chachiwiri chiyani? Matenda osiyanasiyana zochepa otukuka akulu khoma, koma iwo tadulidwa. Mwachitsanzo, mu ufulu kulowa magazi venous, ndi lamanzere - wolumikizira. Ngati mwamvetsetsa funso za mfundo zimenezi mtima, ndiye ife tikhoza kunena chinthu chimodzi motsimikiza: onse zipangizo, mitsempha, mitsempha ndi mavavu olumikizidwa kwa mzake, ndipo io thupi wapadera, amene munthu akhoza kukhalapo.

matenda a mtima

Mwatsoka, mtima - uyu si munthu lopitirira zoyenda makina. thupi ili mosalekeza ntchito ndi maonekedwe a kubadwa anthu mpaka mpweya wake womaliza padziko lapansi. Kale za mmene ntchito izo anachita. Anthu ena osati ngofunika aliyense ichi ndi wapanikizika mtima wanga. Other palimodzi kuyiwala za linakhalapo n'kusiya thanzi lawo. N'zosadabwitsa kuti matenda a mtima kwambiri masiku ano. Amachitiridwa ndi chiwerengero chachikulu cha anthu. Ndipo pamene zizindikiro ambiri palibe vuto lililonse koyamba, zizindikiro. Thukuta, mwachitsanzo. Kapena edema. Ngati munthu amadwala kulephera congestive mtima, madzimadzi anapitiriza mu thupi. Chifukwa cha ichi, ndipo pali edemas. Kuwonjezeka lakuthwa kulemera kapena, Tikawonetsetsa kuchepetsa ake amasonyeza matenda a mtima. Kufupika kwa mpweya - chizindikiro china. Kumene, iwo anatinso mu matenda a m'mapapo (COPD kapena mphumu) Komabe, kulephera mtima chimaimira. Chifuwa ululu kufalikira kwa pamimba, khosi, nsagwada, mikono, kapena zigawo zina za thupi - ichi ndi chifukwa nkhawa. Usaope kupita kwa dokotala. Ndi mtima kuti trifled ndi chifukwa sachedwa matenda ndi mankhwala ndi osafunika kwambiri. Apo ayi, ndiye kuti zikhoza kukhala mochedwa kwambiri.
