Kunamahemuhemu ukuthi izinja zinjengabanini bazo. Ukufana kwangaphandle kwesinye isikhathi kuyamangaza, kepha ososayensi base-Australia baqhubekise futhi banquma ukucubungula umsebenzi wenhliziyo nge-pair of "Master + inja ayithandayo."
Amabili ngakomabili lenja yomnikazi ehlukaniswe ngokuxhuma ze-cartiodeators kubo abahlanganyele ekuhlolweni. Ngemuva kwalokho baphinde babumbane, futhi ukubonwa nokubalwa kwaqhubeka. Kwavela ukuthi izinhliziyo zezilwane ezifuywayo nabantu, yize zilwa ngamandla ahlukile, kepha zisenzeka ngesigqi esisodwa, futhi ngaphakathi kwephethini eyodwa yenhliziyo.
UMia Cobb umcwaningi ovela eMelbourne Universitat waphetha ngokuthi lapho umuntu esebenzisa isikhathi nenja yakhe, ngenxa yokwehluka kwenhliziyo esheshayo, ukushaya kwenhliziyo yabantu kwehlisa kancane, kulandela isigqi senhliziyo yokushaya kwenhliziyo. Lo mphumela unethemba elikhulu ngesimo sonke se-cardiosystem yomuntu.
Iqiniso ngukuthi umsebenzi wenhliziyo uthonywa kakhulu yingcindezi kanye nenani elikhulu lezinto ezingokomzwelo ezithinta izinga lokushaya kwenhliziyo, futhi ukwehla kwalesi sigqi kusiza kakhulu. Konke okunye, izinja zisiza umzimba ukuthi umelane nentuthuko ye-glaucoma ngendlela efanayo yemilingo.
