Kapangidwe ka mtima

Ndi palibe chinsinsi kuti mtima - limba waukulu mu thupi la munthu. Ngakhale chimene anthu, ntchito ya mtima anasonyeza pamene pa uliri mkati ndi mawonekedwe akunja. Mtima - mosalekeza zikugwira ntchito tikuyamba injini, amene mapampu ziwiya zedi magazi. Single amaganiza otaya magazi anaonetsetsa mavavu mtima, amene anatsegula opanikizika mu njira imodzi. The Mapangano mtima minofu molondola komanso momveka bwino, kumverera zimamuchulukira amazipanga lalikulu. moyo wake wonse mtima wa munthu ntchito mosalekeza, amene mfundozo moyo uno.

Zonse makalasi zolimbitsa thupi kapena zolimbitsa mtima kugwira ntchito molimbika, ndipo monga chotsatira cha minofu mtima wasindikizidwa. Komabe, monga mphamvu kwambiri chifukwa ventricles. Ngati minofu mtima wotopa kuchokera ku ntchito sangathe kuwapeza mwazi wonse akulowa M'mimbamo angathe congestive kukulitsa mtima ndi matenda a mtima. Kumvetsetsa njira izi, m'pofunika wofufuza chinthu chotero monga "kapangidwe ka mtima."

Kapangidwe kunja mtima

Kawirikawiri, pamene liwu lakuti "mtima" munthu akuganizira yaing'ono wofiira mtima anamulasa ndi muvi Cupid. Komabe, ngati maganizo, ndi n'zoona? Kumene ayi.

akalumikidzidwa mtima - phirilo flattened mu anteroposterior malangizo. Kapangidwe ka mtima zikusonyeza kusiyana pakati m'munsi ndi pamwamba. Base - gawo yaitali kuti walangizidwa lamanja, ndi pang'ono kumbuyo, chapamwamba - m'munsi tapered gawo, motero, opita ku lamanzere, pansi ndi pang'ono patsogolo.

Pamwamba pa thupi tikhoza kuona protrusions zosiyanasiyana ndi grooves kuti apange Mitsempha. Yaikulu ya iwo ali ndi maina awo. Mwachitsanzo, coronal sulcus chimene chimafika transversely kwa olamulira a mtima komanso kunja ventricles delimitation Cholozera ndi atria. Komanso, pamwamba pa mtima ali kumbuyo ndi kutsogolo interventricular grooves - zizindikiro kunja malire yamitsempha yamagazi. Pano komanso kugona ziwiya mtima. Onse, pali mbali ziwiri pamwamba pa mtima - makutu atria.

Kapangidwe mkati mwa mtima

Mkati mtima n'kovuta kwambiri. Chinthu choyamba muyenera kulabadira kuphunzira kapangidwe ka mtima, ndi chakuti pali mavavu anayi, kuonetsetsa kayendedwe ka magazi mu njira kutsogolo ndiponso kupewa ulendo wake wobwerera panopa. Tricuspid ndi mitral mavavu atrioventricular nadzawasankhula ventricles ku atria, m'mapapo mwanga ndi kung'ambika mavavu semilunar - ventricles ya mitsempha lalikulu. Onse a iwo amagwira kwa mafupa fibrous za mtima. chimango mtima imakhala minofu wandiweyani connective, umene ndi kuthandiza minofu ndi mavavu.

Ambiri ananena kapangidwe ka mtima, nkofunika kuona kuti mtima kwambiri imakhala ya zipinda zinayi izi: atrium kumanzere, atrium lamanja, kumanzere ventricle ndi ventricle bwino. Onse a iwo ankasiyana partitions. The atrium kumanzere zikuphatikizapo mtsempha m'mapapo mwanga mu bwino - dzenje. Ku lamanzere ndi lamanja ventricles zili mtsempha wamagazi m'mapapo mwanga ndi kukwera msempha, motero. The atrium lamanja ndi kumanzere ventricle kutseka lalikulu kufalitsidwa, ndi atrium anachoka ndi ventricle bwino - ndi yaing'ono bwalo.

Pamwamba mkati mwa zipindazo mtima ndi mavavu Ng'ona ndi wosanjikiza otchedwa maselo za indofeliyamu - endocardium. Mu minofu subendocardial munali fibroblasts, kolajeni ndi ulusi zotanuka, mitsempha mitsempha, zinthu conductive a dongosolo. Chimaposa izi m'mnyewa wamtima minofu - minofu wandiweyani wosanjikiza wapangidwa ndi maselo mtima minofu. Onani kuti kunja myocardium kumachitika wosanjikiza mafuta ndi minofu connective, lomwe lili ndi mitsempha kupita minofu wosanjikiza mtima, mtima ndi ziwiya lalikulu.

Kapangidwe ka mtima - chidwi kwambiri ndi zofunika mphindi mu thunthu la munthu. Only comprehended mpaka mapeto a mokoma onse m'magazini ino, inu mukhoza kumvetsa zimene ziri mkati thupi lathu ndi mmene zamoyo anthu.
