The nemamiriro mwoyo

Hazvina chakavanzika kuti mwoyo - mukuru nhengo mumuviri womunhu. Kunyange zvazvo chii vanhu, basa mwoyo unoratidzwa sezvaakaita wayo womukati ehurumende uye kwokunze chimiro. Heart - akaramba kushanda yainakidza injini, izvo pumps midziyo rakawanda ropa. Single madziro chokubuda ropa kunosimbiswa mwoyo mavharuvhu, izvo akasvinudzwa pasi nevamwe rimwe divi. The pomwoyo zvibvumirano zvakarurama uye zvakajeka, ndichinzwa zadzisa kusimba guru. All ake upenyu mwoyo womunhu anoshanda nguva dzose, izvo chokwadi inotsigira upenyu uhwu.

Constant muviri zvidzidzo kana muviri kuti mwoyo nesimba, uye sezvo migumisiro pomwoyo rakanamwa. Zvisinei, sezvo vanokwanisa ichiwedzerwa ventricles. ropa rose kana mwoyo tsandanyama waneta kubasa uye havagoni haangavawani anopinda mhango anogona kuva congestive mwoyo akawedzera uye mwoyo nokukundikana. Kuti tinzwisise azvaiitwa nani, zvinokosha yakawanda yokunyatsoongorora chinhu chakadai "nemamiriro womwoyo."

The kwokunze nemamiriro mwoyo

Kazhinji, kana shoko "mwoyo" munhu achifungidzira mwoyo duku mutsvuku kubayiwa nokuda nomuseve Cupid. Zvisinei, kana maonero akadaro, ndiyo nyaya here? Chokwadika kwete.

Heart zvitarisiko - cône, flattened ari anteroposterior negwara. The nemamiriro mwoyo zvinoreva akasiyanisa pakati nechigadziko uye kumusoro. Base - nevazukuru chikamu kuti akarayira kurudyi, kumusoro uye zvishoma shure, rokumusoro - yakaderera tapered mugove ukuwo, rinotungamirirwa kuruboshwe, pasi uye zvishoma mberi.

Pamusoro pemvura muviri ichi tinogona kuziva miganhu dzakawanda dzakasiyana uye grooves kuti zvinoumba midziyo ropa. Remasangano vavo vane mazita avo pachavo. Izvi Somuenzaniso, in coronal sulcus, izvo kunosvika transversely kuti akabatana mwoyo uye zvimwewo delimitation Pointer ventricles uye atria. Uyezve, pose mwoyo une rwemberi uye pamberi interventricular grooves - zvimwewo zviratidzo ventricular miganhu. Pano zvakare nhema mwoyo midziyo. Vose, pane growths maviri pamusoro pemvura mwoyo - the atria nzeve.

The womukati nemamiriro mwoyo

Inside mwoyo zvaoma. Chinhu chokutanga unofanira kuteerera kudzidza maumbirwo mwoyo, ndiye chokwadi kuti pane mavharuvhu mana, kuona kufamba ropa iri mberi negwara uye chinonditadzisa chidzoke ano. Tricuspid uye mitral atrioventricular mavharuvhu kuparadzanisa ventricles kubva atria, pulmonary uye kutsemuka semilunar mavharuvhu - ventricles huru arteries. Vose vari vasiyana fibrous marangwanda mwoyo. Heart furemu ine kwazvo gobvu connective rinenge riri kutsigira kuti tsandanyama uye mavharuvhu.

Kazhinji, kutsanangura mamiriro kwomwoyo, zvakakosha kuziva kuti mwoyo chaizvo rine makamuri mana kuruboshwe atrium, kurudyi atrium, kuruboshwe ventricle uye zvakarurama ventricle. Vose dzakaparadzaniswa partitions. The akasiya atrium zvinosanganisira pulmonary tsinga kupinda kurudyi - negomba. Kubva kuruboshwe uye zvakarurama ventricles dziri pulmonary tsinga uye vachikwira yeropa, ukuwo. The rworudyi atrium uye rworuboshwe ventricle kuvhara hombe kuparadzirwa, kuruboshwe atrium uye yakarurama ventricle - chiduku denderedzwa.

Pemvura mwoyo makamuri mavharuvhu yomukati vari mudungwe pamwe paiva vainzi masero endothelial - endocardium. In subendocardial zvinyama ine fibroblasts, collagen uye kwakavharwa nenyama fibers, tsinga, mutsinga, ari conductive zvemamiriro ezvinhu. Ndakatengesa ichi myocardial zvinyama - the tsandanyama guru rukoko anoumbwa cardiac tsandanyama masero. Cherechedza kuti kunze myocardium kunoitika rukoko mafuta uye connective rinenge anofukidza tsinga kuenda tsandanyama rukoko mwoyo, mwoyo nemidziyo zvikuru.

nemamiriro mwoyo - a anonakidza uye inokosha kuripo kwevanhu. Chete nokuenzanisa kusvikira pakuguma vose nuances mumagazini ino, unogona kunzwisisa zviri mukati muviri wedu uye sei kutsigira upenyu hwevanhu.
