Inima este \u00eemp\u0103r\u021bit\u0103 \u00een dou\u0103 p\u0103r\u021bi, care sunt separate de un perete muscular (septul). Exist\u0103 dou\u0103 camere pe fiecare parte a inimii, un atriu deasupra \u0219i un ventricul dedesubt. Partea dreapt\u0103 a inimii prime\u0219te s\u00e2nge s\u0103rac \u00een oxigen din corp, prin vase numite vene. Ea pompeaz\u0103 s\u00e2ngele \u00een pl\u0103m\u00e2ni, unde acesta este \u00eembog\u0103\u021bit cu oxigen. Partea st\u00e2ng\u0103 a inimii prime\u0219te acest s\u00e2nge de la pl\u0103m\u00e2ni \u0219i \u00eel pompeaz\u0103 \u00een toate organele corpului prin vasele numite artere. \u00cencepe de la cea mai mare arter\u0103, care se nume\u0219te aort\u0103. Valvele dintre atrii \u0219i ventricule se numesc valvele atrioventriculare (valva mitral\u0103 din st\u00e2nga, valva tricuspid\u0103 din dreapta). Acestea \u00eempiedic\u0103 s\u00e2ngele s\u0103 curg\u0103 \u00een direc\u021bia gre\u0219it\u0103. Valva pulmonar\u0103 \u0219i valva aortic\u0103 controleaz\u0103 ie\u0219irea s\u00e2ngelui din ventriculul drept \u0219i respectiv st\u00e2ng. Valvele se deschid atunci c\u00e2nd se atinge o anumit\u0103 presiune \u00een ventricul, permi\u021b\u00e2nd astfel s\u00e2ngelui s\u0103 curg\u0103 \u00een pl\u0103m\u00e2n (din ventriculul drept) sau \u00een corp \u0219i organele sale (din ventriculul st\u00e2ng).<\/p>\n
Inima este un mu\u0219chi care pompeaz\u0103 de 60 p\u00e2n\u0103 la 80 de ori pe minut, \u00eentreaga ta via\u021b\u0103. Prin urmare, are nevoie de cantit\u0103\u021bi mari de oxigen \u0219i nutrien\u021bi pentru a func\u021biona \u00een mod corespunz\u0103tor. Arterele coronare alimenteaz\u0103 inima cu s\u00e2ngele extrem de necesar.<\/p>\n","protected":false},"excerpt":{"rendered":"
