Sonke kungenzeka ukuthi sizibuze ukuthi kungani izinja zine- impumulo emanzi. Kunemibono eminingi ngalokhu, noma impendulo ingatholakala ezifundweni ezenziwa ososayensi emashumini eminyaka amuva nje. Bayakuqinisekisa ukuthi lo mswakama ufeza umsebenzi wokusiza inja ukuthi ilawule izinga layo lokushisa futhi ibambe nephunga.
Amakhala la manzi, ajwayelekile kakhulu ezilwaneni ezincelisayo, ngokwesayensi abizwa ngokuthi i-rhinarium. Bahlala bemanzi ngenxa izindlala ezimbili eziseceleni Zinikeza uketshezi oluningi. Zitholakala ngaphakathi kwe- impumulo bese bekhipha amakhala ngepayipi elincane elingamasentimitha amabili. Ukukhotha ngakolunye uhlangothi kuyasiza ekugcineni lomswakama.
Ngokuphikisana nalokho kwesinye isikhathi okushiwoyo, okushiwo uketshezi akuyona ukujuluka, kepha mucous. Kuyasiza inja ukuncibilikisa amakhemikhali asemoyeni ukuze ikwazi ukumunca isikhumba se-truffle, okuyilapho amaseli athola iphunga khona. I-mucosa isebenza njengohlobo lwesicabucabu, ibamba izigidi zamamolekyuli, yona ikhethe kusengaphambili ukuthi iyiphi kuzoyiswa ebuchosheni.
Ngasikhathi sinye, lesi sikhwehlela sisiza isilwane ukuthi kulinganisa izinga lokushisa kwakho, ukuba yinto ehambisanayo nokuhefuzela. Kuvuna ukuqedwa kokushisa komzimba okweqile, njengoba kukhonjisiwe ezifundweni ezahlukahlukene, phakathi kwazo esingabala igama elenziwa ososayensi u-CM Blatt no-CR Taylor, obizwa nge- "Thermal panting in dogs: the latal gland gland, a source of water for cooling ngokuhwamuka », futhi yanyatheliswa ngumagazini wesayensi I-Science Magazine.
Ngakolunye uhlangothi, kukhona labo abathi ikhala elomile ezinjeni kuwuphawu lwesifo. Lokhu akudingeki kube njalo, ngoba lapho bephumule isifonyo sabo sihlala somile ngokwengeziwe, ngenkathi sisesimweni esisebenzayo i-mucosa ifihlwa kalula. Kodwa-ke, uma siqaphela ukuthi i-truffle yesilwane sethu asivamile ukuba manzi, kufanele vakashela udokotela wezilwane.
