Yin zubar da jinin ta cikin zuciya bai zama mai sauƙi ba kamar yadda yake iya gani. Zuciya itace kwayar halitta, ta yin amfani da ɗakuna hudu, huɗu hudu , da jini masu yawa don samar da jini ga jiki. Hanyoyin da ke gudana ta hanyar zuciya yana da mahimmanci, tare da jini yana motsawa cikin zuciya, to, huhu, kafin ya dawo cikin zuciya.
Jinin ya dawo cikin zuciya daga jiki ta hanyar manyan jini guda biyu wanda ake kira cava mafi girma da kuma ƙananan baya.
Wannan jini yana ɗauke da iskar oxygen kadan, kamar yadda yake dawowa daga jiki inda ake amfani da oxygen.
Jinin da ya fara shiga cikin dama. Daga nan sai ya gudana ta hanyar tarin gado a hannun dama ventricle. Lokacin da zuciya ta yi zafi, ventricle ya zubar da jinin ta hanyar kwarjin kwakwalwa cikin kwakwalwa. Wannan maganin yana da mahimmanci: Abin sani ne kawai a cikin jikin mutum wanda ke ɗauke da jini mai kwakwalwa.
Jigilar ƙwaƙwalwar jini tana ɗauke da jini ga huhu inda yake "samo oxygen", kuma ya bar cikin huhu kuma ya koma cikin zuciya ta hanyar kwayoyin huhu. Jinin ya shiga hagu na hagu, to sai ya sauka ta cikin bazawar hawan ciki cikin ventricle hagu. Hakanan hagu na hagu ya zubar da jini ta hanyar kwandon ruwa, kuma a cikin kwari, jini wanda zai kai ga sauran jikin.
Ciki, ba haka ba ne?
Wannan zai iya sauƙaƙe: Ba tare da bawullan, hanzarin zuciya ba zai iya inganta karfi ko matsa lamba ba.
Zai zama kamar yin famfo sama da taya mai laushi tare da babbar rami a cikinta. Kuna iya buge duk abin da kuke so, amma taya ba zai taba fadi ba. A cikin zuciya, jini zai shiga cikin ɗakin, kuma kawai ya shiga cikin ɗakin kuma fitar da bawul din a ƙasa, ko sama a cikin kuskuren hanya duk lokacin da ventricle yayi kokarin zub da jini.
Maimakon haka, bawul din saman saman kowace ventricle yana buɗe don bada izinin cikawa, yayin bawul din a kasa ya tabbatar da jinin ba zai fita ba. Lokacin da ventricle ya cika, ɗigon ɓangaren sama ya rufe kuma ƙaho na kasa ya buɗe. Cikin ventricle yana zubar da jinin da karfi ta hanyar basho. Ainihin, shafuka suna riƙe da jinin da ke gudana cikin daidaitaccen jagora ta hanyar zuciya.
Don taƙaita:
Jinin ya bar zuciya kuma ya tafi kyallen takalmin jiki don samar da iskar oxygen kuma ya aikata wasu ayyuka da suke taimakawa rayuwa. Blood sa'an nan kuma ya koma cikin zuciya. Na farko, jinin yana gudana a hannun dama, ya wuce ta bashin tricuspid, kuma ya sa hanyar shiga cikin hannun dama na ventricle. Daga nan sai motsa ta hanyar kwarjin kwakwalwa, a cikin rikici na huhu zuwa ga huhu. Bayan ɗaukar oxygen a cikin huhu, jinin yana motsa daga cikin huhu a cikin kwakwalwan huhu, a cikin hagu na hagu, ta hanyar basirar motsi, kuma a cikin motsi mai hagu wanda ya motsa jini ga jiki ta hanyar kwandon ruwa. Da zarar jinin ya fita daga zuciya yana cikin filin da yake gudana zuwa sassa daban-daban na jiki.
