Imbali

Ukuthuthuka kwezimbali kuyindlela eyinkimbinkimbi futhi ebalulekile emijikelezweni wokuphila kwezitshalo eziqhakazayo. Ezitshalweni eziningi, izimbali ziyakwazi ukukhiqiza Amangqamuzana obulili obubili. Impova, engakhiqiza amangqamuzana obulili abesilisa, ithuthwa phakathi kwezingxenye zesilisa nezesifazane zezimbali ngokuthutha impova. Ukuthuthwa kwempova kungenzeka phakathi kwezitshalo ezihlukene, njengokuthuthwa impova, noma phakathi kwezimbali esitshalweni esifanayo noma ngisho nembali efanayo, njengokukhishwa impova. Ukuhamba kwempova kungabangelwa izilwane, njengezinyoni nezinambuzane, noma izinto ezingaphili njengomoya namanzi. Umbala nesakhiwo sezimbali kusiza inqubo yempova.
