Umbhobho ligama eliqhelekileyo lenxalenye iphela. Ngokubanzi yenziwe lilungu elinye okanye nangaphezulu. Umbhobho yinxalenye yokugqibela yenkqubo yokutshiza kunye nelona candelo libaluleke kakhulu. Umgangatho wayo uchaphazela ngokuthe ngqo isiphumo sokutshiza.

I-orifice ibhekisa kwindawo ephuma kuyo amanzi. Uninzi lwee-orifices zemilomo yesetyhula. Ngokwethiyori, encinci ubukhulu be-orifice yombhobho, kufutshane nefom yokutshiza kukunkungu, inkulu i-orifice, kunye nokuhamba kokutshiza. Mkhulu, ngakumbi njengemvula enkulu okanye kwanemvula enkulu. Imilo yesitshizi yemilomo yemilomo igqitywa ngokudityaniswa kobume be-orifice kunye nolwakhiwo lwangaphakathi lwemilomo. Isantya esiphezulu sokujikeleza kolwelo, kwaye ukuba i-orifice isetyhula, imilo yejet yikhowuni epheleleyo. Ukuba ii-grooves ezimbini ezimile nkqo ezimiswe ngu-V zinqunyiwe kwi-orifice setyhula, imilo yejet iya kuba sisikwere. (Ubume bePyramidi). Kuyabonakala ukuba i-orifice inefuthe elikhulu kwimilomo.

Singumenzi wemilomo yobungcali ovela eTshayina, uyilo lwemilomo etyebileyo kunye namava okuvelisa, ukusombulula zonke iingxaki kukhetho lwemilomo, ulungiselelo kunye nesicelo sakho. Ukuba ufuna ukufumana ikowuteshini esezantsi yemveliso, nceda uzive ukhululekile ukuqhagamshelana nathi.
