Igazi emjikelezweni womzimba libuyela endlini yolwazi
Impendulo ithi: Ithwalwa nge-carbon dioxide iye enhliziyweni nge-atrium elungile.
Umzimba unesimiso sokujikeleza kwegazi lapho usebenzisa igazi eligcwele isikhutha, elibuyiselwa enhliziyweni ngemva kokuhlaziya izicubu nokuthola umoya-mpilo.
Igazi eligcwele i-carbon dioxide lithunyelwa ku-atrium efanele, bese litholwa ku-ventricle efanele, ukuze inhliziyo isebenze ukulimpompa futhi emaphashini ukuze ithole umoya-mpilo.
Le nqubo iyenzeka unomphela emzimbeni, futhi kubalulekile ukugcina impilo yomuntu.
