Kunzwa chinhu chakakosha kumhuka. Inovabatsira kuona zvikara, kutsvaga mhuka, kutaurirana, uye kufamba nharaunda yavo. Mhuka dzakashanduka hunyanzvi hwekunzwa hwakasiyana zvichienderana nekwadzinogara uye nemararamiro. Dzimwe mhuka, dzakaita sezviremwaremwa nema dolphin, dzakashandura kugona kushandisa echolocation kufamba kwadziri. Imbwa nekatsi, dzinova mhuka dzinovaraidza dzakakurumbira, dzakagadzirawo hunyanzvi hwekunzwa hunovabatsira kutaurirana nevaridzi vadzo uye nenyika yakavatenderedza.
Anatomy yeNzeve: Manzwiro Imbwa neKatsi
Imbwa nekatsi zvine maitiro akafanana enzeve, asi pane zvimwe zvakasiyana. Mhuka dzose dziri mbiri dzine mativi matatu panzeve dzadzo: nzeve yokunze, nzeve yapakati, uye nzeve yomukati. Nzeve yekunze ndiyo ine basa rekuunganidza masaisai eruzha, ukuwo nzeve yepakati ichikudza ruzha nekuitumira mukati menzeve. Nzeve yomukati ndiyo iyo inzwi rinogadziriswa uye rinotumirwa kuuropi. Imbwa dzine nzeve refu kupfuura katsi, izvo zvinodzibatsira kutora ruzha kubva kure. Katsi, kune rumwe rutivi, dzine chimiro chakatanhamara chekunzwa, icho chinodzibatsira kuwana manzwi nenzira kwayo.
