Kuye ngenjongo nesakhiwo sawo, izintambo zikagesi zingahlukaniswa ngezinhlobo ezihlukahlukene, okuhlanganisa{0}}amakhebuli anamandla kagesi aphansi,{1}}amakhebuli aphezulu{1}}, izintambo zokulawula, namakhebuli okuxhumana. Lezi zintambo zisetshenziswa kakhulu ekuhlinzekeni kukagesi emadolobheni, ekukhiqizeni izimboni, nasekudluliseleni ezokuxhumana.
Ekuphakeleni kukagesi emadolobheni, izintambo zikagesi zinomsebenzi obalulekile wokuhlinzeka ngogesi kubahlali namabhizinisi. Njengoba zigqitshwe ngaphansi komhlaba noma phezulu, lezi zintambo zidlulisela ugesi ophehlwa yizikhungo zikagesi ezindaweni ezihlukahlukene zokusetshenziswa, okuqinisekisa ukusebenza okuvamile kwamadolobha. Izintambo zikagesi nazo zidlala indima ebalulekile ekukhiqizweni kwezimboni. Baxhuma amadivaysi ahlukahlukene, baqinisekise ukusebenza kahle kwemigqa yokukhiqiza nokuthuthukisa umkhiqizo. Ekudluliselweni kwezokuxhumana, izintambo zikagesi zisetshenziselwa ukudlulisa amasignali kanye nedatha, okuqinisekisa ukuxhumana okungavimbekile.
